Definitions
- Recommendation speeds per highway / road section which, based on a rapid management of all current and statistical traffic data, recalculated in very short time intervals and output to the road users.
- the present invention is in the field of congestion avoidance in a highway / road network. More specifically, this invention is a computer-implemented method which is in the real-time domain of influencing traffic within a highway / road network.
- the currently used methods / methods for controlling the congestion problem are mostly based on estimation methods for determining the current traffic condition. Furthermore, the control strategies offered by these methods / methods include the indication of alternative routes or the use of relatively rigid traffic control devices mounted on certain points of a highway / road network, possibly with the aid of
- This computer-implemented invention pursues a very subtle and differentiated approach to the analysis or digital reconstruction / mapping and influence of real-time traffic flow on road / highway sections:
- One approach of the present invention is a 1-1 real-time Reconstruction / mapping of the current traffic flow on road / motorway sections using a fine sensor network.
- this computer-implemented invention pursues a more direct, finer and more effective intervention strategy: Based on the 1-1 real-time reconstruction / mapping of the current traffic flow, this invention determines at short intervals in addition to traffic variables such as
- Recommendation speeds for selected highway / road sections using forecasting and analysis tools are recommended speed limits that can be adhered to to prevent a predicted critical traffic condition or to prevent the extension of a recognized critical traffic condition - critical traffic conditions include congestion and congested traffic. These recommendation speeds are provided and stored for transmission to the road users by means of traffic signs, in-car information systems, navis etc. in a server / computer system.
- the approach of the present invention is to provide any road user with a recommended speed in real time, at any time and in any location in a highway / road network, in real time, to adhere to a predicted critical traffic condition or
- sensors All highways, part of the motorway network or road network are provided with sensors. These sensors are at a distance of several meters along the direction of travel e.g. attached to crash barriers, guide posts or other mounting options, see Fig. 1-100.
- the series of linearly arranged one behind the other per direction of travel sensors we call a 'sensor array'.
- the sensors may be minimal or simple devices capable of detecting a vehicle ahead, for example by ultrasound, electromagnetic waves or otherwise.
- the signals generated in this way are stored in a storage medium / server B Fig.2-210 or database system (DBS) D Fig.2-220 with information about the respective sensor and the time of reception or generation of this signal collected and stored.
- DBS database system
- Storage medium / server B is to be regarded as part of system A - see Fig.2.
- This server group can also consist of a server system.
- the server system A contains in particular a modern database system (DBS) D Fig.2-220.
- DBS database system
- DBMS database management system
- the database management system (DBMS) of the database system D should be able to process large amounts of data analytically or numerically in a very short time. This is with in-memory based DBS's such as e.g. SAP HANA - possible.
- the signals of the above-mentioned sensors can be indirectly transferred to the server system D, but also directly to Fig.2-215.
- Each area of a motorway / road network - can be any size, contiguous or discontinuous - provided with the sensors described above defines a table whose number of columns corresponds to the number of tracks or the number of sensor rows see Fig. 1 per direction and off There are as many lines as there are sensors in the sensor rows on the respective motorway / road network.
- the possible entries in this table should be either 0 or 1 or comparable Boolean entries in the sense of 'no' or 'yes'. In the following, we will select the value range ⁇ 0,1 ⁇ representative of the possible Boolean entries, see Fig. 3.
- DBT database table
- a D be the DBT of a chosen motorway / road network.
- the entries of AD are denoted by A (k, l). This means in summary that each field A (k, l) is assigned a sensor.
- the entries of A D are all initial, ie 0.
- the sensors detect preceding vehicles. In the case of detection, information is sent directly or indirectly to the server system D Fig.2-220.
- the corresponding field A (k, l) receives the entry 1.
- This field is filled with the entry 1 for a 'very short time' T Abb.4-410 - eg in the seconds or milliseconds range then set to 0 if no further signal for A (k, l) has arrived.
- Each of these microintervals Mj Fig.4-430 has a lower and an upper limit Uj, Fig.4-415 and Oj, Fig.4-420.
- Fig.4-420 of a microinterval M i5 Fig.4-430 we obtain (with a short delay due to the data transmission) the DBT Ai Fig.4-440 with entries Aj (k, 1) see Fig. 3.
- Traffic specifics such as traffic density, current speed, etc. are determined section by section, Fig.6-620. These current traffic specifics but also the raw data ⁇ A, ⁇ can be stored in a statistical / historical DBS C Fig.2-230 Fig.2-225, Fig.6-625 or Fig.6-615.
- the data situation described above allows us, for example, at the end of certain time periods (Z Fig.4-400, ZR Fig.5-500, ...) from the previously collected and / or cached data (database tables) traffic-specific parameters such as density, flow rate, etc. by analytical, numerical or statistical methods for a certain, not so remote time (eg in 2, 5, 10 minutes, half an hour in the future) to predict.
- traffic-specific parameters such as density, flow rate, etc.
- analytical, numerical or statistical methods for a certain, not so remote time (eg in 2, 5, 10 minutes, half an hour in the future) to predict.
- Fig.6-660 determined for relevant areas of the motorway / road network, whose consideration counteracts the emergence of these critical traffic conditions or formulated in other words, to maintain the traffic in an optimal way and thus stifles the development of critical traffic conditions in the bud or prevented their expansion.
- recommendation rates can be determined using simulation / forecasting algorithms Fig.6-650. These recommendation rates should be determined in a balanced / reasonable way u. A. taking into account the maximum permissible speed on the respective motorway / road sections. For example, default values from a statistical database system Fig.6-645 can be used to determine these recommendation speeds, which are validated using simulation algorithms.
- traffic conditions which lead to critical traffic conditions via simulation algorithms, can be stored in the following form in a statistical / historical database (DB), Fig. 6-635:
- the traffic state variables calculated for these traffic conditions such as density,
- Historical statistical recommendation speeds can then be used to automatically determine current recommendation speeds in the server system, Fig.6-645.
- the traffic state variables determined periodically in real time can be compared with the data on critical traffic states stored in the statistical / historical DB C by means of suitable comparison algorithms, FIGS. 6-635: Should a traffic condition be found in this DB which is sufficient is close to the traffic state variables calculated in real time, so can the stored
- the statistical / historical DB can be preconfigured with data of critical traffic conditions, i. That this DB can be fed in advance with statistical theoretical traffic conditions, which would lead to critical traffic conditions - to this recommendation speeds are linked.
- Comparative algorithms using a statistical DB ultimately lead to the Recommendation speeds.
- simulation algorithms can be used without the use of comparison algorithms or comparison algorithms without the use of simulation algorithms.
- the recommendation speeds determined for each motorway / road section of the selected Autobahi road network and period which can be determined in a short time via the server system D Fig. 2220 or the statistical / historical DB C Fig. 2-230, are sent to the respective highway - / road sections sent Fig.7 and by the driver via a mobile app / "application", a navigation device Fig.7-710, an in-car information system Fig.7-720 or external information systems Fig.7-700 or in another form Fig.7-730 be noted in relatively short intervals.
- the goal is to reduce congestion enormously.
- the above-described method of traffic flow mapping on a part of a motorway / road network section can be used to calculate recommendation speeds in sections for the resolution of this traffic condition and for the above described use (output on signs, in-car information systems, etc.).
- Highway network and networks of large / long roads are the focus of this idea. This is because:
- the approach of the present invention is to any road user at any time and anywhere in a highway / road network if necessary, provide a recommended speed in real time, adherence to which prevents the prediction or avoidance of the extension of a detected critical traffic condition.
- the central idea of this paper is the determination of recommendation speeds, by the transmission of the traffic flow into a very fast processing DBMS and the forecast of the traffic flow obtained from the collected data and the return of the recommendation speeds to the road users.
- this computer-implemented invention pursues a very subtle and differentiated approach to the analysis or digital reconstruction / mapping and influencing of the real-time traffic flow on road and / or highway sections.
- the previously known methods are mostly based on estimation methods for determining the traffic condition.
- One approach of the present invention is a 1 -1 real-time reconstruction / mapping of the actual traffic flow on road and / or highway sections by means of a fine sensor network.
- this computer-implemented invention pursues a more direct, finer and more effective intervention strategy:
- a method implemented as a software determines at short intervals, in addition to traffic variables such as flow speed and traffic per motorway / road section, recommendation speeds for selected motorway sections. These recommendation speeds are recommended speed attitude to prevent forecasting or avoiding the extension of a recognized critical traffic condition. These recommendation speeds are provided and stored for transmission to the road users by means of traffic signs, in-car information systems, navis etc. in a server / computer system.
- This invention includes a very fine process that tackles the problem of congestion at the root and counteracts the emergence of critical traffic conditions.
- this invention represents a real complement to the action portfolio of modern traffic management.
