Intersection with optimized settings and traffic control method of the intersection

Abstract

The invention relates to an intersection with optimized settings. Central double solid lines or an isolated column are / is displaced and arranged to form the intersection with more exit lanes and few entrance lanes; each of a left traffic lane and a right traffic lane is newly provided with a stop line at a distance away from the stop line of the intersection, and an exit or an entrance is arranged behind each stop line; and a car lane dividing line of one exit lane is changed to the central double solid lines or the isolated column, at least one traffic lane is always kept on the left of the car lane dividing line to serve as the exit lane, and the traffic lane on the right is set to a dual-function traffic lane. The dual-function traffic lane and the right traffic lane can be used as the exit lane or the entrance lane for related driving cars under the situation of separated traffic control time. The invention further provides a traffic control method, phase positions are divided into four groups based on a signal machine or a signal control center arranged at the intersection with the optimized settings, each group has four phase positions for connecting with corresponding signal lamps of the intersection, and the four groups in traffic are sequentially and cyclically executed, so that the entrance and the exit lanes of the passage intersection can be increased to the greatest extent, the passing capacity and the passing quantity are improved, the jam can be effectively relieved, and the traffic delay, the oil consumption and the pollution can be reduced.

Description

technical field [0001] The invention belongs to the field of traffic engineering, and in particular relates to an optimally set crossing and a traffic control method thereof. Background technique [0002] Road traffic congestion is a problem in every city. The traffic capacity and traffic volume of intersections are not large, which is the main reason for traffic congestion. The best way to solve intersection congestion is to widen intersections and set more lanes than road sections. However, there is no land for widening lanes at intersections. Existing two-way more than the crossing of road of four lanes is more through tightening design, and one-way is set as entrance road one more than road section lane, is equally one more than exit road. The patent application with the application number 2007101440780 is to open an exit at the position where the double solid line in the center of the existing intersection or the separation barrier is a distance away from the stop line...

AI Technical Summary

Problems solved by technology

This setting and traffic control method seem to increase the traffic lanes at the intersection, but the signal cycle time is longer. In each signal cycle, the vehicles that arrive at the intersection at the same time are artificially divided into two parts, and the vehicles that pass later have to wait to pass first. The green light time of the vehicle, the delay time of driving at the intersection is more, and the fuel consumption and pollution are also greater

[0004] Driving in the direction you want to go before reaching the intersection needs to change lanes, and drivers who drive from the upstream intersection have the feeling of rushing to the green light at the next intersection, so there are often speeding and speeding phenomena in the road section, and there are often traffic jams and random lane changes and other bad behaviors, which often cause congestion and even accidents, so that road traffic is always in a bad cycle

If there are straight left-turn entrances in each direction of the intersection, the above-mentioned bad behaviors and the congestion and even accidents caused by them will be mostly avoided. However, due to the limited lanes at the existing intersections, it is impossible to set up straight left-turn entrances at each intersection.
