Road programming method based on speeds

Abstract

The invention provides a road programming method based on speeds. The method comprises the steps of: collecting road network data in a programming region; obtaining control node important degrees according to the road network data, and determining the road network scale of each level of control nodes; obtaining a running speed of the road network, and determining the design speed of the road network; according to the design speed and road network parameters, carrying out traffic programming. According to the invention, in a set time target in the programming region, the road network scale of each level of control nodes is calculated and determined according to the important degrees, and the running speed of the road network is obtained, and levels of routes are determined based on the road network functions, the design speed, the traffic amount, the economic factor and the like, and the orientation is determined based on geographical factors and natural environment factors, the travelling time is saved, the travelling efficiency is improved, the travelling experience is enhanced, regional connection is more close, the economic development is facilitated under a high-efficiency transportation environment, and the social life standard is improved.

Description

technical field [0001] The invention relates to the traffic field, in particular to a speed-based road planning method. Background technique [0002] The development of road traffic directly restricts the development of the country's economy and the improvement of people's living standards. With the rapid development of road traffic in my country in recent years, the topic of traffic has directly become a hot topic in society. With the continuous expansion of traffic demand, it is particularly important to plan the traffic network reasonably. At present, the traffic planning methods in our country are mainly divided into the following two types: the four-stage method and the capacity method. The four-stage method uses four steps of traffic generation, traffic distribution, traffic mode division, and traffic flow distribution to plan the target year for each road flow in the planning area. The capacity method uses the limitation of the maximum capacity of the road bottlenec...

AI Technical Summary

Problems solved by technology

The capacity method uses the limitation of the maximum capacity of the road bottleneck to control the traffic distribution of the road network, which is more suitable for bridges and tunnels, so it has certain limitations

At the same time, the above two methods are planned from the perspective of supply and demand balance, but they can only plan the level and form of a certain road section according to the allocated traffic flow. When a certain road section cannot meet the traffic flow demand, it will become a potential bottleneck section. Thus affecting the operating efficiency of a larger area or even the entire road network, greatly increasing the travel time

Neither of the existing two methods can guarantee the stability of running time in the whole region, therefore, a new speed-based road planning method is urgently needed to solve the above problems
