Embodiment 1

[0029] This embodiment provides a method for acquiring road traffic information, such as figure 1 As shown, the method includes:

[0030] 101. Establish the corresponding relationship between the bus lines and the roads in the electronic map.

[0031] Wherein, the corresponding relationship is the distance between adjacent stations on the same bus line, the route, the positional relationship between the stations and the starting point of the road.

[0032] 102. Acquiring the consumption data of the all-in-one card on the bus card-swiping machine.

[0033] Wherein, the consumption data includes device address ID, line ID, station ID, and time, and the device ID is the unique ID of the credit card machine on the bus.

[0034] 103. Group the consumption data with the same device ID and vehicle ID into one group.

[0035] Wherein, the consumption data of the same device ID are arranged in order of time, that is, among the consumption data, the consumption data with the earlier ...

Embodiment 2

[0051] This embodiment provides a method for acquiring road traffic information, such as image 3 As shown, the method includes:

[0052] 301. Obtain bus line data.

[0053] Wherein, the bus line data is the line table, station table and equipment table of all bus lines, the line table includes line ID, line name, total number of stations, station ID list, line shape, and the station table includes station ID, Site name, site coordinates, the device table includes device ID, line ID.

[0054] 302 . Map the route shape of each bus route in the bus route data and the positions of all stations included in the bus route to an electronic map.

[0055] Such as Figure 5 As shown, for example, line L1 corresponds to road sequence r1, r2, r3, r4, r5, r6, r7, r8, station S1 corresponds to road sequence r1, station S2 corresponds to road sequence r3, station S3 corresponds to road sequence r6, and station S4 corresponds to Road sequence r8.

[0056] 303. Calculate the length of the...

Abstract

The embodiment of the invention discloses a method and device for acquiring road traffic information, and solves the problem of incomprehensive coverage of traffic information when a floating car technology is adopted to provide traffic information. The method comprises the following steps: corresponding a bus route onto an electronic map, and calculating the effective running time between two adjacent stations according to the card swiping time of the all-purpose card; and finally, calculating the road average travel time according to the effective running time and the road sequence length corresponding to the effective running time. The method and the device are applicable to the field of intelligent traffic systems.

Description

technical field [0001] The invention relates to the field of intelligent traffic systems, in particular to a method and device for acquiring road traffic information. Background technique [0002] Intelligent Transportation System (ITS for short) is established by effectively integrating advanced information technology, data communication transmission technology, electronic sensing technology, electronic control technology and computer processing technology into the entire ground traffic management system. It is a real-time, accurate and efficient integrated transportation management system that plays a role in a wide range and in all directions. [0003] The main goal of intelligent transportation is to realize the modernization of the entire urban transportation system, and the key link in the modernization of urban transportation is to provide real-time dynamic traffic information services to alleviate traffic congestion. The real-time traffic information of the road has...
