Problems solved by technology

It is neither scientific nor clear about the number of cars that can be accommodated on urban roads, nor can it solve the current situation of congestion.
It is also inhumane, which limits the urgent need of car owners to use the car, and cannot arrange travel time, travel routes and mileage according to their own needs
At the same time, when the peak congestion period comes, there is nothing to do

Embodiment Construction

[0012] 1. Calculation method for roads that can accommodate vehicles:

[0013] (1), lane mileage=road mileage*number of lanes of this road.

[0014] (2), distance between vehicles = vehicle body length + distance from the vehicle in front.

[0015] (3), capacity = lane mileage / travel distance*saturation rate.

[0016] (4), total capacity = sum of each capacity.

[0017] The total vehicle capacity is the number of vehicles that can be accommodated on all roads in the city. The limit is to limit the number of travel vehicles within the range of the capacity that can be accommodated.

[0018] 2. Calculation method of restricted distance for restricted vehicles:

[0019] (1), total mileage of traffic flow = total capacity * vehicle speed * daily time limit

[0020] (2), the total mileage to be divided = the total mileage of the traffic flow * (1-the percentage of the unrestricted vehicle volume and the total vehicle volume).

[0021] (3), monthly mileage of restricted cars =...

Abstract

The invention belongs to the technical field of city road passage and particularly relates to a jam problem solving passage method for city roads. The method is mainly characterized by comprising the steps of limiting flow, wherein the traffic flow is limited according to the number of vehicles which can be contained by the roads in a city; limiting mileage, wherein the traveling mileage of a single vehicle is limited according to the mileage of the roads in the city; limiting time, wherein time periods are limited according to the rush hours of the traffic flow. The method has the main advantages that the city roads as the limited road resource can be distributed to each limited vehicle fairly and justly; a vehicle owner can flexibly adjust and reasonably arrange the journey and travel time of the owner according to the distributed mileage of the vehicle, and the right is prevented from being violated; the traffic flow is limited according to the number of vehicles which can be contained by the roads in the city, and therefore traffic jam is relieved.

Description

technical field [0001] The invention belongs to the technical field of urban road traffic, and relates to a traffic method for unblocking urban roads. Background technique [0002] As urban road congestion becomes more and more serious, urban road traffic operators have introduced a series of congestion relief policies and taken corresponding measures. For example, limit travel with odd and even numbers, buy cars by lottery, increase congestion charges, improve traffic facilities, etc. Although these have played a certain role, they are not a long-term solution. Urban road resources are limited and constant, while the increase of urban vehicles is unlimited and variable, and it is constantly changing every day and every month. It is neither scientific nor clear about the number of cars that can be accommodated on urban roads, nor can it solve the current situation of congestion. It is also inhumane, which limits the urgent needs of car owners to use cars, and cannot arran...
