Problems solved by technology

The disadvantage is that it cannot accurately reflect the real feelings of traffic congestion. In some special cases such as extreme weather, traffic control, and regional crossing, the difference between the evaluation results and the actual feelings is large, and it cannot truly reflect the feelings of the public.

Abstract

The invention discloses a calculation method based on urban road congestion index. The method comprises the following steps: step 1, calculating the arithmetic mean value of the road section speed; step 2, calculating the road section speed standard deviation; step 3, calculating the average speed of the road section ; Step four, calculate the traffic flow factor of the road section; Step five, calculate the lane number factor of the road section; Step six, calculate the extreme weather factor of the road section; Step seven, calculate the traffic control factor of the road section; Step eight, calculate the congestion index of the road section; Nine, calculate the congestion index of the area; step ten, divide the congestion index. The method of the present invention replaces the algorithm of calculating the traffic congestion index of the road network with the average speed and the number of vehicles as the main parameters, and considers the weight of other factors such as the number of lanes, road design speed, extreme weather, traffic control, etc., so that the congestion index is closer to people. congestion perception.

Description

technical field [0001] The invention relates to traffic operation index, in particular to a calculation method based on urban road congestion index. Background technique [0002] With the development of the city, the urban road environment is becoming more and more complex. The main components of the complex factors are: the increase of motor vehicles, the increase of non-motor vehicles (tricycles, bicycles, animal-drawn vehicles), the increase of new energy vehicles, urbanization, Defects in the bearing capacity of the original roads (motor vehicle lanes and non-motor vehicle lanes), population increase, irregular construction of existing buildings and future buildings, irregular green belts, unreasonable distribution of underground trenches, increased street lamps, and improper design of cross-section sidewalks Reasonable. [0003] The above factors have resulted in insufficient carrying capacity of urban roads, and road congestion occurs more or less in each city, and th...
