Technical Field

The invention belongs to the technical field of intelligent traffic, and particularly relates to a median strip in the middle of a road.

Background

The traffic volume is a random number, and the traffic volume at different time and different places is changed, namely the space-time distribution characteristic of the traffic volume. The separation of the working and residential areas in cities usually results in a very uneven distribution of the bidirectional traffic flow on roads, especially during the morning and evening rush hours, and the tide phenomenon is obvious, which provides a chance for the generation of variable lanes.

The center bank means a strip facility for dividing a roadway, which is provided in a longitudinal direction of the roadway, for dividing bidirectional traffic and preventing glare, and the center bank will occupy a certain road width. In a conventional road traffic study: some scholars adopt a movable central partition belt, some scholars propose to adopt a portal frame for signal control, and some scholars propose to adopt a variable spike lamp for lane change. However, the movable central separator requires special instruments for movement, and the emptying time is also relatively long; the portal frame cannot ensure that a driver can observe the direction of the traffic lane in real time; although the variable spike lamp can provide real-time traffic guidance for a driver, it cannot prevent glare caused by light during night driving.
