Improvement method for traffic organization of three-lane road and crossing

Abstract

Improvement method for traffic organization of three-lane road and crossing belongs to city road design and traffic management field, applying the road sectional distribution type of footway, automobile way and bicycle way, regulating the order of the automobile way and bicycle way, optimizing the crossing traffic organization with the method that laeotropic automobile turns around the block and the bicycles are lead farther, improving the capacity of the city grade crossing and the road average speed in the condition of two-phase crossing signal control in the crossing. The invention can be used for city road network modification and road network construction.

Description

technical field [0001] The invention belongs to the technical field of urban road design and traffic management. It involves road section design, intersection traffic management and control. Background technique [0002] The traditional road section traffic organization is: sidewalk, bicycle lane (come), motor vehicle lane (come), motor vehicle lane (go), bicycle lane (go), sidewalk. According to whether there is a green belt between the bicycle lane (coming), motor vehicle lane (come), motor vehicle lane (go), and bicycle lane (go), it can be divided into one board, two boards, three boards, and four boards. Four basic section organization modes. In my opinion, no matter what the specific section form is, the cross-section traffic organization on the road is the same. In this explanation, three-panel road is used to refer to this road section traffic organization form, which is hereinafter referred to as traditional three-panel road; narrowly defined three-panel road The...

AI Technical Summary

Problems solved by technology

Foreign experts have also realized that under the condition of large bicycle traffic, the current (such as HCM) method seriously overestimates the traffic capacity of road level intersections

[0007] 2. Deterioration of the micro-land development model

[0010] The section size of the three-panel road is large, which will inevitably make it difficult for pedestrians to cross the street

However, one slab road and three slab roads with dividers are difficult to provide such a safety island.

[0011] 3. High cost of road widening

However, the three-slab road in the narrow sense with green separation belts faces the problem of demolition of green roads, the problem of street lights shifting, and the cost of widening motor vehicle lanes increases.

[0013] 4. Impairment of road traffic capacity

[0049] ②The traditional three-slab road and the existing road network system are not suitable for long-distance traffic diversion and neighborhood detour

[0052] However, there are many traffic attraction points on both sides of the main road, and the OD points of motor vehicles and non-motor vehicles have a high degree of overlap, which is very prone to the phenomenon of superposition of functions of motor vehicles and non-arterial roads
