Method and system for modeling and processing vehicular traffic data and information and applying thereof

A recommended route is searched by the use of traffic information collected in the past. A map/statistical traffic data storage device 3 stores map data including link data of respective links constituting roads on a map, and statistical data including travel time or moving speeds of the respective links determined by statistical values of traffic information collected in the past. Said statistical data is classified every condition of collection of traffic information. A navigation device searches a recommended route from a departure position to a destination by using the map data stored in the map/statistical traffic data storage device and statistical data corresponding to a day type and a weather type which constitute conditions of search, out of statistical data stored in the map/statistical traffic data storage device 3.

A navi-server which is provided with information from a traffic information providing center, and presents and provides information made on the information to a terminal is characterized by being equipped with a first storage means storing the information provided from the traffic information providing center; a traffic jam statistical making means which makes traffic jam statistical information including traffic jam information in a predetermined point and a predetermined zone as well as a reliability of the traffic jam information, based on information stored in the first storage means; and a second storage means storing information made by the traffic jam statistical making means, wherein the navi-server presents and provides the information stored in the second storage means to the terminal, based on a request of the terminal and at a predetermined timing

Display method of navi-server and navigation

A system and method for self-optimizing traffic flow using shared vehicle information that utilizes multiple controllers in dynamic communication to optimize the flow of traffic. The system and method utilizes one or more traffic synchronization controllers (TSCs) (receivers) that receive information from one or more vehicle based transmitters called vehicle information agents (VIAs) and/or a network of traffic control devices (TCDs) associated with the traffic synchronization controllers to determine a variety of information related to traffic within a geographic region, including volume, speed, destination, intended route of the vehicle, as well as other vehicle related information, in order to determine the optimal flow of traffic within the region. The system and method then transmits traffic control signals to the various traffic control devices within the region or adjacent regions in order to optimally control the flow of traffic. The system and method may also share information amongst traffic synchronization controllers within the network in order to optimize the flow of traffic over a larger region.

System and Method for Self-Optimizing Traffic Flow Using Shared Vehicle Information

PROBLEM TO BE SOLVED: To improve the usefulness of a road map displaying device by easily visibly displaying the statistical traffic snarl information in a desired time zone on a desired day of the week so that the present or future traffic condition can be predicted and a driving plan can be made easily. SOLUTION: In a road map memory, statistic traffic snarl information data are stored by correlating the data with each day of the week and each time zone. The statistical traffic snarl information data are obtained by statistically processing the past traffic snarl data. When a traffic snarl information displaying mode is instructed and a day of the week and a time zone are designated (S1), the statistical traffic snarl information data on the designated day of the week and time zone are read out (S3) and traffic snarl marks are superposed on a road map near and along the corresponding road for display (S4).

PROBLEM TO BE SOLVED: To prepare a map database including the newest road regulation information by collecting positional information from a vehicle traveling on a road and collecting the passage number of vehicles traveling on the road by using a link matching method. SOLUTION: A position detection signal from a vehicle 2 traveling on the road is received, the traveling locus of the vehicle 2 is obtained on the basis of the received detection position of the vehicle 2, the traveling locus of the vehicle is matched with a link on the map database, the number of vehicles passed is totalized in each link matched with a plurality of vehicles, and a link of which the number of vehicles passed is less than a threshold is judged as traffic regulation.

Method for determining traffic regulation, and method and program for determining regulation service route

PROBLEM TO BE SOLVED: To collect information about a travel track of a vehicle, to perform dangerous traveling decision of the vehicle based on the information, and to provide warning information to the vehicle or a peripheral vehicle. SOLUTION: Track data of the vehicle traveling on a road are collected (S1), a lane and a road section wherein the vehicle travels are specified by use of a road map database storing road section date in each the lane based on the collected track data of the vehicle (S2), it is detected whether a travel direction of the specified lane of the road section and a traveling direction of the vehicle accord or not (S3), it is decided that the vehicle reversely travels when they are opposite directions (S4), and reverse traveling warning information is outputted when the decision of the reverse traveling is performed (S5, S9).

PROBLEM TO BE SOLVED: To accurately decide traffic information such as a traffic jam degree by considering waiting for a traffic light to change to obtain an accurate travel time when obtaining travel time information by use of information of a probe vehicle. SOLUTION: Position/speed data of the vehicle traveling in a road section are collected (S1), a traffic light waiting time and a frequency of the waiting for the traffic light to change in the road section of the vehicle are calculated based on a collected speed V of the vehicle (S6), and the traffic light waiting time is subtracted from the travel time of the road section (S8) to calculate the net travel time of the road section, and the traffic information such as the traffic jam degree of the road section is decided based on the net travel time (S10).

PROBLEM TO BE SOLVED: To accurately obtain traffic volume in a free flow (non-congestion) state. SOLUTION: Speed data of a vehicle traveling in a road section are collected (S3), and the traffic volume of the road section is estimated by use of prescribed relation between the traffic volume and speed based on the collected speed (S4). The estimated traffic volume is corrected based on one of an occurrence frequency or an occurrence time interval of acceleration/deceleration of the vehicle traveling in the road section, a maximum value of an absolute value of an acceleration of the vehicle traveling in the road section, variation of the speed of the vehicle traveling in the road section, and a lane change frequency of the vehicle traveling in the road section (S8, S9). The correction is based on prediction that a road is congested (not congested) as the occurrence frequency of the acceleration/deceleration is larger (smaller) when the correction is performed based on the occurrence frequency of the acceleration/deceleration of the vehicle, for example. Calculation accuracy of the traffic volume can be improved. COPYRIGHT: (C)2009,JPO&INPIT
