Embodiment 1

[0027] Such as Figure 1-Figure 3 As shown, the free overtaking lane is composed of auxiliary overtaking lanes (new lanes on the same side of a two-lane highway) and overtaking lanes (original lanes).

[0028] In two-lane road sections with heavy traffic volume and frequent overtaking, add a certain length of lane according to the local terrain conditions. Between the overtaking lane and the opposite lane, the "yellow line" is used to separate the traffic flow of the original lane from the traffic flow of the opposite lane, and the traffic flow of this lane is prohibited to use the opposite lane to overtake; at the entrance of the auxiliary overtaking lane, the overtaking lane and the auxiliary lane "White solid lines" are used between the overtaking lanes to guide the original convoy to the auxiliary overtaking lane through signs and markings, and give way to the original lane. After the vehicle enters the auxiliary overtaking lane, the traffic marking between the auxiliary ...

Abstract

The invention provides a method for setting a free overtaking lane on a two-lane highway. The free overtaking lane is composed of an auxiliary overtaking lane added on a local section of a two-lane highway and an original same-direction lane used for overtaking. Protect the safety of drivers on two-lane highways. This method gives the design length of the free overtaking lane, the length of the diverging and converging transition sections and the design width of the free overtaking lane. Compared with the prior art, the construction cost of the present invention is lower, and the traffic signs and markings are cleverly used to solve the traffic conflict problem caused by drivers using the opposite lane to overtake on a two-lane highway; without occupying too much land resources Under the premise of the road, the operation benefit and safety benefit of the two-lane highway are effectively improved. Simultaneously, the invention can also be used for temporary parking of broken-down vehicles and accident vehicles on a two-lane highway, effectively solving the traffic congestion caused by vehicle breakdown and accidents on a two-lane highway.

Description

technical field [0001] The invention relates to a method for setting free overtaking lanes on a two-lane highway. Background technique [0002] Two-lane highway is the most common road form in my country's highway network. Each lane can only serve traffic in one direction. Vehicles must use the opposite lane to overtake, and only when there is sufficient headway in the opposite lane. And when the safe overtaking sight distance can be guaranteed, the driver has the opportunity to change lanes and overtake, otherwise he can only passively follow the vehicle in front all the time. Due to the significant difference in the performance of motor vehicles in my country, the overtaking demand can still appear frequently on roads with little traffic volume; the demand for overtaking on roads with large traffic volume increases significantly, and increases with the increase of traffic volume. Since there is no available lane for overtaking in this direction on a two-lane highway, only ...
