Bus priority large circular intersection

Abstract

The invention provides a bus priority large circular intersection. Bus lanes and inductive signal lights are arranged on the bus priority large circular intersection. In the straight direction of a bus, the bus lanes are arranged inside entrance and exit lanes, and the bus lanes are connected with the bus lanes within a roundabout. The inductive signal lights are arranged at the intersection of aisland line and the bus lane. The control mode of the inductive signal lights is that after the bus is detected 100 meters away from the intersection, the signal light flashes yellow and turns red three seconds later in the direction of the roundabout. After the bus enters the central roundabout, a red light on the side of the entrance lane turns green. After the bus leaves the intersection, the red light on the side of the exit lane turns green. When no bus passes, the inductive signal light remains green. The bus priority large circular intersection influences on the traffic of other vehicles at a lower degree, the bus priority in the circular intersection can be effectively guaranteed, and the overall operation efficiency of traffic flow is improved by reducing the conflict between a huge bus and interwoven vehicles, and thus the influence of the bus priority on the social vehicles is compensated.

Description

technical field [0001] The invention relates to the fields of traffic organization and vehicle-road coordination, in particular to a large roundabout with priority for public transportation. Background technique [0002] Due to various reasons, large roundabouts exist widely in major cities in China. Roundabouts have advantages in reducing direct vehicle conflicts and ensuring continuity of traffic flow. At present, from national to local levels, a consensus has been formed on the development strategy of public transport priority. How to ensure the priority of buses at roundabouts belongs to the category of bus priority strategy. Due to the length of the bus, it is difficult for the bus to interweave with other vehicles at the roundabout, which affects the overall efficiency. Contents of the invention [0003] To address the above problems, the present invention provides a bus-priority large-scale roundabout, which can effectively guarantee the priority of buses in the ...
