METHOD, NETWORK ENTITY AND COMMUNICATION SYSTEM FOR
INCREASING TRAFFIC SECURITY
The present invention relates to the area of traffic
security, particularly to the area of detection of
endangered traffic situations.
Nowadays, most people own mobile communication devices like
cell phones, smartphones, mobile computers or others, and
carry at least some of these devices with them almost all
the time. These devices are frequently not switched off,
and therefore remain continuously in communication
connection with the wireless communication network. Hence,
the mobile communication devices are registered in the
wireless communication network, and data exchange from
and/or to the cell phones can be established easily and
rapidly, assuming that resources in the wireless
communication network are available. Typical mobile
communication devices comprise at least one input device,
e.g. a keypad or a microphone, suitable for data input into
the mobile communication device, and at least one output
device, e.g. a speaker or a display, and are enabled to
exchange data with the wireless communication network.
Wireless communication networks like GSM, UMTS, LTE, or
others are nowadays available at almost any place around
the world. These wireless communication networks provide an
infrastructure, which can be used by mobile communication
devices suitable for use in these wireless communication
networks to transmit and receive any kind of data, nowadays
primarily voice data. The communication networks can be
used at any time, including traffic situations, where users
frequently can even actively use their mobile communication
devices, e.g. their cell phones.
The term traffic situation refers to any kind of situation,
where multiple traffic participants are present in a
certain area and at least one of them is moving, which
occurs in many situations. Such traffic situations include
a person waiting at a bus stop, pedestrians walking along
the road, or a group of children playing next to the road,
where an interaction with other traffic participants may
occur at any time. Traffic situations also refer to
situations where traffic participants are using means of
transport, e.g. a car or a bicycle, and even to use of
self-driven vehicles. In such traffic situations, the
traffic participant can be in an endangered situation
without taking notice, e.g. when a car is approaching a
location of a traffic participant, and the car is not yet
visible or audible. Traffic participants comprise persons,
persons in combination with a means of transport and a
self -driven means of transport.
It is an object of the present invention to provide a
method, a network entity, and a communication system for
increasing traffic security, which can be easily used and
applied, and allow alerting traffic participants in case of
endangered traffic situations rapidly and reliably.
This object is achieved by the independent claims.
Advantageous embodiments are given in the dependent claims.
In particular, the present invention provides a network
entity for increasing traffic security for use in a
wireless communication network, comprising a receiving unit
adapted to receive via the wireless communication network
information from a first mobile communication device, a
processing unit adapted to process the information received
from the first mobile communication device for detecting an
endangered traffic situation, and a transmission unit
adapted to transmit an alerting message via the wireless
communication network to at least one second mobile
communication device in vicinity of the first mobile
communication device upon detection of an endangered
traffic situation.
The present invention also provides a method for increasing
traffic security by use of a wireless communication
network, comprising the steps of receiving information from
a first mobile communication device via the wireless
communication network, processing the information received
from the first mobile communication device for detecting an
endangered traffic situation, and transmitting an alerting
message via the wireless communication network to the at
least one second mobile communication device in vicinity of
the first mobile communication device upon detection of an
endangered traffic situation.
The present invention provides a further method for
increasing traffic security using a communication system
comprising a wireless communication network, a first mobile
communication device for providing information, and at
least one second mobile communication device in vicinity of
the first mobile communication device, comprising the steps
of processing the information from the first mobile
communication device to detect an endangered traffic
situation, transmitting an alerting message via the
wireless communication network to the at least one second
mobile communication device in vicinity of the first mobile
communication device upon detection of an endangered
traffic situation, and generating a user alert on the at
least one second mobile communication device upon reception
of the alerting message.
Furthermore, the present invention provides a communication
system comprising a wireless communication network, a first
mobile communication device, and at least one second mobile
communication device, whereby the communication system is
adapted to perform the above method.
Basic idea of the invention is to automatically detect an
endangered traffic situation by use of the information from
the first mobile communication device and to automatically
generate the user alert at the at least one second mobile
communication device. The endangered traffic situation can
be any traffic situation with an increased probability of
accidents. Generally speaking, endangered traffic
situations can occur in case some of the participants are
not aware of others and/or cannot react on other traffic
participants in an appropriate way. Accordingly, the
detection of an endangered traffic situation comprises
detection of such a particular endangered traffic
situation, e.g. when an accident between traffic
participants using the first mobile communication device
and the at least one second mobile communication device is
automatically predictable with a certain probability. Upon
detection of an endangered traffic situation, the traffic
participant in vicinity to the first mobile communication
device, who is user of the at least one second mobile
communication device, can be alerted by a sending an
alerting message via the wireless communication network to
generate a user alert on the second mobile communication
device, so that the traffic participant using the at least
one second mobile communication device can take care on the
endangered traffic situation, and in particular on the
traffic participant using the first mobile communication
device. Hence, the endangered traffic situation can be
resolved .
The processing of the information can be done within the
network entity, which does not underlie limitations in
respect to computational power, as may be the case for the
first mobile communication device.
The terms first and second mobile communication device
refer to essentially any kind of a mobile communication
device, particularly mobile phones. The difference between
the first and the second mobile communication device is
preferably a logical difference based on whether the
information for detection of the endangered traffic
situation is generated, or the user alert is generated.
Accordingly, any mobile communication device can act at the
same time as first and second mobile communication device.
The second mobile communication device may be a mobile
communication device associated to a means of transport,
e.g. a car, which is either built-in or connected via cable
or a wireless communication link, e.g. via Bluetooth
thereto. Accordingly, the second mobile communication
device may provide the alert via a warning interface to a
dashboard or an in-car multi-media device of the car. When
the at least one second communication device is in
communication connection with the wireless communication
network, i.e. the second communication device is registered
in the wireless communication network, the alerting message
can easily be sent to the at least one second mobile
communication device. Time consuming prior establishment of
a communication connection or registration of the at least
on second mobile communication device for purpose of
transmitting the alerting message is not required. With
more than one second mobile communication device present in
the vicinity of the first mobile communication device, the
alerting message can be sent to multiple or all second
mobile communication devices simultaneously.
This way, traffic security can be increased, since almost
any participant in the traffic situation is equipped with a
mobile communication device, so that no additional devices
are required for detecting the endangered traffic situation
and/or for sending the alerting message to the second
mobile communication device for generating a user alert.
Wireless communication networks are widely available almost
anywhere around the world.
For processing the information and generating the user
alert, software applications can be installed on available
mobile communication devices to convert them into first and
second mobile communication devices. Particular mobile
communication devices do not have to be provided.
At the first mobile communication device, any suitable
input device can provide information, which is processed to
detect an endangered traffic situation.
Vicinity can depend on the traffic situation or can be
defined independently, e.g. by the first mobile
communication device and the second mobile communication
device being located in the same cell of the mobile
communication network.
In a preferred embodiment the processing unit is adapted to
process the information from the first mobile communication
device for performing a classification of the first mobile
communication device. For example, children or elderly
people can generally be considered to be in an endangered
traffic situation, since they may not react in traffic
situations as expected by other traffic participants,
thereby endangering themselves and/or other traffic
participants. Children, who are playing, are usually not
aware of cars passing by on a road next to them, so that
they will likely enter or cross the road without taking
prior notice of these cars. Similarly, persons having
reduced vision will not recognize endangered situations in
advance. Furthermore, traffic participants may be
physically handicapped, so that even after recognizing an
endangered traffic situation they will not be able to leave
this situation appropriately. Accordingly, the detection of
an endangered situation can comprise classifying a traffic
participant using the first mobile communication device as
a general source of endangered traffic situations based on
the information of the first mobile communication device.
In a preferred embodiment the processing unit comprises at
least one neural network and/or a hidden Markov model
adapted to process information from the first mobile
communication device. Classification tasks can be easily
handled by neural networks. Preferably, a multilayer
perceptron is used to receive the information from the
first mobile communication device and to provide as output
classification probabilities, which can be trained from a
database using for example a back propagation algorithm to
detect endangered traffic situations. The neural networks
can process simultaneously different kinds of information
from the first mobile communication device, or just a
single kind of information. Availability of kinds of
information depends on the first mobile communication
device .
In a preferred embodiment the information from the first
mobile communication device comprises audio information
extracted from a microphone as input device. For example,
traffic sound may indicate an endangered situation, e.g.
sound of a braking car. Also, sound of playing children can
be used to classify a traffic participant carrying the
first mobile communication device as a playing child.
Similarly, a user of a first mobile communication device,
who is having a communication, either person-to-person or
via the first mobile communication device, is also likely
to focus on the communication and to be rather careless
about traffic situations.
In a preferred embodiment the information from the first
mobile communication device comprises mobility information
extracted by a GPS-receiver and/or an acceleration sensor
as input device. Mobility information refers to any kind of
information regarding movement of the first mobile
communication device and therefore regarding movement of a
traffic participant carrying the first mobile communication
device. Information regarding movement comprises speed and
direction of a movement and/or strength and direction of an
acceleration, which can be extracted directly or derived
from position information. For example playing children
frequently run around with a movement pattern frequently
changing speed and direction, suitable for classifying them
accordingly. In contrast, an adult pedestrian is generally
proceeding in a certain direction with a relatively
constant velocity, as a different pattern. Such typical
movement profiles can be automatically recognized. In
contrast, a person who is not moving will most probably not
cause an endangered traffic situation. Also detection of
acceleration that will conduct a traffic participant into a
particular danger can be detected.
In a preferred embodiment the information from the first
mobile communication device comprises position information
of the first mobile communication device. Children, who are
playing on a playground far away from a road, cannot cause
endangered traffic situations, since they are in a separate
area. On the other hand, a child, who is approaching a road
with high velocity, is likely to enter the road causing an
endangered traffic situation. The other way round, a car,
which is moving in a pedestrian area, can also be detected
as a cause of an endangered traffic situation. Any kind of
a violation of traffic code, which can be detected by
evaluating position information, can be considered as an
endangered traffic situation. Also an unexpected
acceleration detected by the acceleration sensor can
indicate such an endangered traffic situation. Even though
usually a person who is not moving does not cause an
endangered traffic situation, this can be the case when a
pedestrian is not moving on the middle of a road.
In a preferred embodiment the information from the first
mobile communication device comprises user information
entered via a user interface as input device. This refers
to any kind of information in respect to the person using
the first mobile communication device. E.g. different
buttons can be implemented as user interface for indicating
that the owner of the first mobile communication device is
for example a child, a bicycle rider or a driver of an
emergency vehicle like a police car or an ambulance,
thereby enabling a self -classification of the traffic
participant. Also, the user interface can comprise an
emergency button, indicating e.g. a temporary medical
emergency of the respective traffic participant, so that
his current participation in the particular traffic
situation causes an endangered traffic situation.
The information processed for detecting an endangered
traffic situation may be unprocessed or pre-processing
information, which may already contain a dimensionality
reduction. It may be information relevant for detection of
an endangered traffic situation, which is carved from the
information as gathered by the input devices. The preprocessed
information may be compressed information reduced
in size .
In a preferred embodiment the receiving unit is adapted to
receive mobility information of the first mobile
communication device from the wireless communication
network, and the processing unit is adapted to additionally
process the mobility information of the first mobile
communication device for detecting an endangered traffic
situation. Mobility information of the first mobile
communication may comprise position and/or movement
information as described above. With the wireless
communication network providing this information, it can be
processed for detecting an endangered traffic situation,
although the first mobile communication device does not
provide this information. Mobility information can be
provided e.g. by means of assisted GPS (A-GPS) or
triangulation techniques.
In a preferred embodiment the receiving unit is adapted to
receive mobility information of the at least one second
mobile communication device via the wireless communication
network, and the processing unit is adapted to additionally
process mobility information of the at least one second
mobile communication device for detecting an endangered
traffic situation. The mobility information may be provided
from the second mobile communication device itself or the
mobile communication network. The principles described
above in respect to processing mobility information apply.
Preferably, mobility information of the first and the
second mobile communication device are both processed, so
that particular endangered traffic situations may be
detected .
In a preferred embodiment the transmission unit is adapted
to transmit the alerting message as a broadcast message to
second mobile communication devices in vicinity to the
first mobile communication device via the wireless
communication network. The broadcast message allows
alerting multiple traffic participants simultaneously and
therefore in an efficient way.
In a preferred embodiment the transmission unit is adapted
to transmit the alerting message containing mobility
information of the first mobile communication device. With
the mobility information, the second mobile communication
device can evaluate the alerting message received from the
base station to decide whether a user alert has to be
generated or not. For example, in case of a second mobile
communication device used by car driver, an endangered
traffic situation can be irrelevant, when the car is not
moving. Second mobile communication devices close by the
first mobile communication device, so that the detected
endangered traffic situation is relevant for them, thereby
defining vicinity, may be detected, so that the alerting
message can be transmitted to these second mobile
communication devices.
In a preferred embodiment the wireless communication
network is arranged in a cell structure with one base
station serving mobile communication devices located in a
cell, and the step of transmitting an alerting message via
the wireless communication network to the at least one
second mobile communication device in vicinity of the first
mobile communication device comprises transmitting the
alerting message to at least one second mobile
communication device served by the same base station as the
first mobile communication device. Accordingly, the serving
base station is indicating vicinity between the first and
the second mobile communication device.
In a preferred embodiment the step of evaluating
information from the first mobile communication device to
detect an endangered traffic situation comprises evaluating
the information within the first mobile communication
device, and the step of transmitting an alerting message
via the wireless communication network to the at least one
second mobile communication device comprises sending the
alerting message from the first mobile communication
device. Once the endangered traffic situation has been
detected, the alerting message can be transmitted rapidly
from the first mobile communication device to the wireless
communication network, so that a time delay due to transfer
of the information to the network does not occur and the
detection of the endangered traffic situation is
independent from resources of the wireless communication
network. The information can be processed by an application
running on the first mobile communication device. Since
data transmission in wireless communication networks
usually generates costs to the user, this is a costsensitive
way for alerting second mobile communication
devices .
In a preferred embodiment the step of processing
information from the first mobile communication device
comprises evaluating information within the first mobile
communication device and transmitting an evaluation result
to an alerting device of the wireless communication
network, and the step of transmitting an alerting message
via the wireless communication network to the at least one
second mobile communication device comprises sending the
alerting message from the alerting device. Also the network
entity as described above can be used as alerting device.
The principles of the processing unit of the network entity
can be applied to a processing unit of the first mobile
communication devices for performing a detection of an
endangered traffic situation within the first mobile
communication device.
In a preferred embodiment the communication system
additionally comprises a network entity as described above,
whereby the communication system is adapted to perform the
above described method for use in the network entity. The
network entity can be a component of the wireless
communication network or be connected thereto.
Although some feature have been described with reference to
an apparatus, it is obvious for a person skilled in the art
that these feature can be similarly applied to the above
method, and vice-versa.
Some embodiments of apparatus and/or methods in accordance
with embodiments of the present invention are now
described, by way of example only, and with reference to
the accompanying drawings, in which:
Fig. 1 shows a schematic view a communication system for
increasing traffic security according to a first
embodiment of the invention, and
Fig. 2 shows a detailed schematic view illustrating a
first mobile communication device of the
communication system of Fig. 1 ,
Fig. 3 shows a detailed schematic view illustrating a
network entity according to the first embodiment,
Fig. 4 shows a schematic view illustrating a
communication system for increasing traffic
security by detection of an endangered traffic
situation according to a second embodiment, and
Fig. 5 shows a detailed schematic view illustrating a
first mobile communication device of the
communication system of Fig. 4 ,
A first embodiment will be described with respect to
Figures 1 to 3 .
Fig. 1 schematically shows a communication system 2 0
comprising a wireless communication network 21, a first
mobile communication device 1 , which is denoted MSI, and at
least one second mobile communication device 2 , which is
denoted MS2 . The wireless communication network 2 1
comprises a base station 3 , also denoted as BS, defining a
cell 4 of the wireless communication network 20, and a
network connection 13, which is indicated by the cloud
denoted IP. The Mobile communication devices 1 , 2 are
served by base station 3 of cell 4 . Although only one
second mobile communication device 2 is shown in Fig. 1 by
way of example, multiple second mobile communication
devices 2 can be located within the cell 4 . The
communication system 2 0 according to this embodiment is
based on the UMTS or LTE-standard .
As best shown in Figure 2 , the first mobile communication
device 1 comprises a microphone 5 , a GPS-receiver 6 , an
acceleration sensor 7 , and a manual warning button 8 as
input devices. The manual warning button 8 in this
embodiment is a button indicating whether a person, i.e. a
traffic participant, carrying the first mobile
communication device 1 is a child or not.
Information extracted from these input devices 5 , 6 , 7 , 8
is passed to pre-processing unit 9 . The pre-processing unit
9 comprises an audio feature extraction unit 10 and a
mobility feature extraction unit 11, which are logical
units within the pre-processing unit 9 . The audio feature
extraction unit 10 receives audio information from the
microphone 5 , and the mobility feature extraction unit 11
receives location information from the GPS receiver 6 and
acceleration information from the acceleration sensor 7 ,
and combines the provided information, which is partly
redundant, to reliably provide information regarding
position, velocity and acceleration of the first mobile
communication device 1.
The information from the audio feature extraction unit 10
and the mobility feature extraction unit 11 is combined
together with the information from the manual warning
button 8 in the pre-processing unit 9 , which performs a
pre-processing of the information, already containing a
dimensionality reduction of the data, carving out relevant
information for further processing, and data compression.
This pre-processed information is transferred from the
first mobile communication device 1 via the wireless
communication network 2 1 to a network entity 14, which is
shown in detail in Fig. 3 . The network entity 14 comprises
a receiving unit 15, which receives the information via the
base station 3 and the network connection 13.
The wireless communication network 2 1 in this embodiment
performs an independent determination of the position of
the first mobile communication device 1 . The wireless
communication network 2 1 performs the detection using
triangulation and/or assisted GPS (A-GPS) . This is
particularly important for first mobile communication
devices 1 not having a GPS-receiver 6 . For first mobile
communication devices 1 having a GPS-receiver 6 , the
detection of the location of the first mobile communication
device 1 by the wireless communication network 2 1 provides
redundant information.
The network entity 14 further comprises a processing unit
16, which is implemented as a neural network combining a
multi-layer perceptron with a back-propagation algorithm.
Accordingly, the processing unit 16 processes audio
information from the microphone 5 , mobility information
from the first mobile communication device 1 based on its
GPS-receiver 6 and acceleration sensor 7 , and the
information from the manual warning button 8 , and the
mobility information of the first mobile communication
device 1 from the wireless communication network 21. The
processing unit 16 comprises a neural network and a hidden
Markov model adapted to process the information from the
first mobile communication device 1 to detect an endangered
traffic situation by way of classification.
Upon detection of an endangered traffic situation the
network entity 14 transmits from its transmission unit 17
an alerting message via the wireless communication network
2 1 to multiple second mobile communication devices 2 , as
indicated in Fig. 1 . The alerting message in this
embodiment contains mobility information of the first
mobile communication device 1 , particularly location
information and movement information, for further
evaluation by the second mobile communication device 2 .
The alerting message is sent to the base station 3 of the
cell 4 serving the first mobile communication device 1 .
Since the alerting message is sent to the base station 3
serving the first mobile communication device 1 , the
respective base station 3 is supposed to be the closest
base station 3 and to cover the vicinity of the first
mobile communication device 1 . As indicated in Fig. 1 , the
base station 3 sends the alerting message to all second
mobile communication devices 2 within the cell 4 a s a
broadcast message.
The second mobile communication device 2 , which is not
shown in detail, comprises a GPS-receiver for providing
mobility information, i .e. location and movement
information. The second mobile communication device 2
evaluates its own mobility information and generates the
user alert under consideration of the received alerting
message as a general user alert, when the distance between
the first and second mobile communication devices 1 , 2 is
below a given threshold. Accordingly, a user of the second
mobile communication device 2 can react upon the user alert
and participate in resolving the endangered traffic
situation .
In a modified embodiment, only part of the information from
the first mobile communication device 1 , i.e. information
from the input devices 5 , 6 , 7 , 8 , is transmitted from the
first mobile communication device 1 to the network entity
14. The remaining part of the extracted information is
processed within the first mobile communication device 1 ,
and the evaluation result is transmitted via the wireless
communication network 2 1 to the network entity 14.
In a further alternative embodiment, the network entity 14
receives at its receiving unit 15 mobility information from
second mobile communication devices 2 via the wireless
communication network 21. The processing unit 16
additionally processes the mobility information of the
second mobile communication devices 2 for detecting an
endangered traffic situation. Accordingly, the network
entity 14 identifies a set of second mobile communication
devices 2 , which are involved in the endangered situation
due to their position relative t o the first mobile
communication device 1 , and transmits the alerting request
to these second mobile communication devices 2 via the
wireless communication network 21.
In a further modified embodiment, the network entity 14 is
an integral part of the wireless communication network 2 .
A second embodiment of a communication system 2 0 is shown
with reference to Figures 4 and 5 . Like components of the
communication system 2 0 are denoted with same reference
numerals .
As shown in Fig. 4 , the communication system 2 0 comprises a
wireless communication network 21, from which only a base
station 3 is shown, a first mobile communication device 1
and at least one second mobile communication device 2 in
accordance with the first embodiment. The wireless
communication network 2 1 in this embodiment is a network
according to the GSM-standard.
In accordance with the first mobile communication device 1
of the first embodiment, the first mobile communication
device 1 of the second embodiment, which is best seen in
Fig. 5 , comprises a microphone 5 , a GPS receiver 6 , an
acceleration sensor 7 and a manual warning button 8 as
input devices, which are identical to the afore-mentioned
input devices 5 , 6 , 7 , 8 . The first mobile communication
device 1 further comprises a processing and evaluation unit
25, which comprises an audio feature extraction unit 10 and
a mobility feature extraction unit 11 in accordance with
the first embodiment. The processing and evaluation unit 25
also comprises a processing unit 16 in accordance with the
processing unit 16 of the network entity 14 of the first
embodiment. Although located i n the first mobile
communication device 1 , the implementation and behavior of
the processing unit 16 is identical to the already
described processing unit 16.
After the detection of the endangered traffic situation,
the first mobile communication device 1 transmits an
alerting message to the wireless communication network 21.
In particular, the first mobile communication device 1
transmits the alerting message to base station 3 of its
cell 4 . The respective base station 3 is assumed by
definition to be the closest base station 3 , since it
serves the first mobile communication device 1 , although
other base stations 3 may be located geometrically closer
to the first mobile communication device 1 , depending e.g.
on communication conditions and characteristics of the
wireless communication network 21. Base station 3 is
further assumed to cover the vicinity thereof, since second
mobile communication devices 2 close by the first mobile
communication device 1 are probably served by the same base
station 3 . The alerting message in this embodiment contains
mobility information of the first mobile communication
device 1 . As indicated in Fig. 4 , the base station 3 sends
the alerting message to all second mobile communication
devices 2 within the cell 4 as a broadcast message.
As already described with reference to the first
embodiment, a user alert at the second mobile communication
device 2 is only generated under evaluation of its mobility
information. The user alert is generated depending on
whether the mobility information of the first and second
mobile communication device 1 , 2 indicates that the mobile
communication devices 1 , 2 will approximate each other
closer than a predefined threshold.
In an alternative embodiment, the base station 3 comprises
a not shown alerting unit, which receives an evaluation
result for the detection of an endangered traffic situation
from the first mobile communication device 1 . The alerting
unit then generates the alerting message and sends it to
all second mobile communication devices 2 within the cell 4
as broadcast message.
The present inventions may be embodied in other specific
apparatus and/or methods. The described embodiments are to
be considered in all respects as only illustrative and not
restrictive. In particular, the scope of the invention is
indicated by the appended claims rather than by the

within the meaning and range of equivalency of the claims
are to be embraced within their scope.
