Problems solved by technology

[0002] Due to the limitations of early urban planning, many urban road constructions are difficult to meet the ever-increasing traffic volume, and urban arterial roads bear a huge traffic load, and most of the intersections on the main roads of the urban road network in my country are signal-controlled intersections, respectively. When single-point signal control is performed, vehicles frequently stop at intersections, which leads to traffic problems such as low efficiency of road network operation and travel delays

Embodiment 1

[0067] The present invention provides a kind of urban road green belt decision support method based on floating car technology, comprising the following steps:

[0068] S1: According to the obtained data information of a plurality of floating cars, an intersection location set is obtained, and the intersection location set includes intersection locations of multiple traffic lights;

[0069] The S1 is specifically:

[0070] Acquiring data information of multiple floating vehicles, said data information including vehicle number, position, speed and time point;

[0071] According to the data information of the plurality of floating cars, obtain the positions where the speed of all floating cars is 0, and obtain the position set;

[0072] According to the location set, multiple suspected intersection locations are obtained;

[0073] Sequentially obtain the average stay time of all floating vehicles within the preset distance range from each suspected intersection position, and i...

Embodiment 2

[0090] The present invention provides a decision support terminal for urban road green wave zone based on floating car technology, which includes a memory, a processor, and a computer program stored on the memory and operable on the processor. When the processor executes the program, it realizes The following steps:

[0091] S1: According to the obtained data information of a plurality of floating cars, an intersection location set is obtained, and the intersection location set includes intersection locations of multiple traffic lights;

[0092] The S1 is specifically:

[0093] Acquiring data information of multiple floating vehicles, said data information including vehicle number, position, speed and time point;

[0094] According to the data information of the plurality of floating cars, obtain the positions where the speed of all floating cars is 0, and obtain the position set;

[0095] According to the location set, multiple suspected intersection locations are obtained;...

Embodiment 3

[0113] 1. Use the on-board information terminal of the floating vehicle to collect the vehicle number u, position l, speed v, and time point t with a fixed time period T during the vehicle's driving process to obtain the driving data sequence, and pass the collected driving data sequence through mobile cellular communication technology is sent to the data center;

[0114] 2. The data center analyzes the speed of driving, extracts intersection nodes with a vehicle speed of 0 and a large number of vehicles (more than 100,000 vehicles), and saves the position of this node in the traffic light intersection set R;

[0115] 3. Determine whether the average residence time of vehicles at each intersection node is within the preset time range (0-3 minutes); if not, delete the intersection node; if so, perform step 4;

[0116] 4. Determine the traffic light intersection, and save the traffic light intersection node in the set R1;

[0117] 5. The data center analyzes the driving data, e...

Abstract

The present invention provides a method and a terminal for urban road green wave band decision support based on a floating vehicle technology. The method comprises the following steps of: obtaining acrossing position set according to obtained data information of a plurality of floating vehicles, wherein the crossing position set comprises crossing positions of a plurality of traffic lights; according to the crossing position set, obtaining a plurality of road sections; according to the data information of the plurality of floating vehicles, calculating average time of all the floating vehicles passing through each road section, and calculating one traffic flow of each road section; and if one difference of average time of each two adjacent road sections is in a preset first time range andone difference of traffic flows of each two adjacent road sections is in a preset flow range, determining that each two adjacent road sections are road sections being suitable for achieving a green wave band. The method and the terminal for urban road green wave band decision support based on the floating vehicle technology can provide an accurate green wave band road section for various trafficinformation service system so as to effectively improve pass capability of a main road in an urban area, reduce the vehicle parking rate and the traffic delay and guarantee operation efficiency of a road network.
