Hierarchical indication system and method for crossroad vehicle traffic

Abstract

The invention relates to a hierarchical indication system and method for crossroad vehicle traffic. The system comprises a primary indication system and a secondary indication system which are arranged along a crossroad entrance lane, wherein the primary indication system is arranged between the secondary indication system and a crossroad, the primary indication system comprises a primary stop line, multiple strands of primary running lanes, a traffic flow identification device and variable traffic mark lines, the primary stop line is arranged at the foremost end of a travelling direction, thetraffic flow identification device is arranged at a front end of the primary stop line, each variable traffic mark line is arranged on each strand of primary running lane, the secondary indication system comprises a secondary stop line, multiple strands of secondary running lanes, a traffic flow identification device and variable traffic mark lines, the secondary stop line is arranged at the foremost end of the travelling direction, the multiple strands of secondary running lines are continued with the primary running lanes, the traffic flow identification device is arranged at a front end ofthe secondary stop line, and each variable traffic mark line is arranged on each strand of secondary running lane. With the system provided by the technical scheme, the vehicle passing efficiency ofa road at the crossroad can be improved, and the congestion condition is reduced.

Description

technical field [0001] The invention relates to the technical field of road traffic, in particular to a system and method for classifying vehicle traffic at an intersection. Background technique [0002] With the development of cities, traffic congestion has increasingly become a great obstacle affecting people's travel efficiency. Traffic jams are more likely to occur near intersections due to lower traffic speeds at intersections. Especially the roads in the central urban area where it is not suitable to widen the intersection to increase the number of lanes due to the limitation of road space conditions, the congestion is particularly severe. At present, the traditional intersections mainly rely on the traffic lights at the intersections for traffic indication. In the case of a limited number of dedicated traffic lanes in each direction, it may cause a large number of vehicles to queue up in some lanes, even when the traffic lights change. Phase, that is, after changing...

Problems solved by technology

At present, the traditional intersections mainly rely on the traffic lights at the intersections for traffic indication. In the case of a limited number of dedicated traffic lanes in each direction, it may cause a large number of vehicles to queue up in some lanes, even when the traffic lights change. Phase, that is, after changing the current traffic direction indicator signal, there are still some vehicles in the lane that have not passed in time, which will affect the rear vehicles that can pass according to the current traffic signal signal, further aggravate the congestion and reduce the traffic efficiency
