Embodiment Construction
[0018] The invention distinguishes the driving characteristics of the vehicles in the port area and investigates the driving data to establish an intersection simulation model suitable for collecting and distributing ports. The average control delay of the vehicle is obtained through the simulation results, so as to determine its service level. have better pertinence
[0019] The purpose of the invention is to overcome the above-mentioned deficiencies of the prior art, and in combination with the traffic characteristics in the port area, propose a comprehensive evaluation method facing the crossing of the port gathering and transportation port. For this reason, the scheme adopted by the present invention is as follows:
[0020] (1) According to the characteristics of large vehicles in the port area, it is possible to analyze the influence of different models on vehicle acceleration, which is actually speed.
[0021] (2) Analyzing the process of vehicles decelerating in advanc...

The invention belongs to the technical filed of road evaluation. Aiming to combine the characteristics of harbour district transportation, the invention provides an evaluation method for standard of service at crossings in a gathering and transportation port. The technical scheme adopted by the invention is characterized in that the evaluation method relating to the standard of service at crossings comprises the following steps: 1, analyzing the accelerated speed of a vehicle in a port area; 2, analyzing the influence of signal lights on the vehicle action; 3, determining the car following rule; 4, determining the lane changing rule of the vehicle; and 5, modeling to obtain a simulation result, then counting the average delaying of the vehicles, determining the standard of service at the crossings and giving the corresponding improvement advice. The method provided by the invention is mainly used for the road evaluating occasions.
Description
technical field [0001] The invention belongs to the technical field of road evaluation, and in particular relates to a comprehensive evaluation method of intersection saturation flow rate and service level. Background technique [0002] A level intersection is an area formed by two or more roads intersecting at the same level. Its function is to connect the roads to form a road network, so that traffic flows in different directions can gather, interweave and diverge in this area. When the traffic volume develops to exceed the capacity that the self-organization of the intersection can handle, it is directed by setting up external traffic signals, and the traffic signals are used to allocate traffic rights of traffic in different directions on each road section in time. At this time, it is possible to pass this The maximum traffic flow at the intersection is the capacity of the signalized intersection, which is the sum of the capacities of all entrance sections. [0003] In ...
