Embodiment Construction

[0055] Aiming at the level intersections between the ring roads and urban roads on the outskirts of the city, the ring road is the main channel for trucks to enter the expressway, so there will be a large number of trucks turning left on the urban arterial road to enter the ring road. The operating efficiency of an intersection depends on the saturated flow rate released by vehicles; compared with passenger cars, trucks have the characteristics of large volume, low speed, and poor maneuverability. As the proportion of freight vehicles increases, the interference between passenger and freight vehicles will intensify, which will inevitably greatly affect the left turn release efficiency of the intersection under the condition of mixed passenger and freight vehicles. The present invention considers setting up special left-turn lanes for trucks to reduce the interference of mixed traffic of passengers and goods, and increase the turning radius of left-turn trucks to ensure efficien...

Abstract

The invention belongs to the technical field of intersection canalization design. In order to make up the blank of the research field of a special left-turning lane for a truck and provide a basis for arranging the special left-turning lane for the truck at intersection, the invention adopts the technical scheme that a method for arranging the special left-turning lane for a separating type truck comprises the following steps of: (1) judging if arranging the special left-turning lane for the truck according to the calculation for a critical condition for arranging the special left-turning lane for the truck; (2) analyzing a right arranging condition for the special left-turning lane for the truck; (3) analyzing an auxiliary condition for a separating type left-turning lane; and (4) performing intersection signal timing on the special left-turning lane for the separating type truck. The method provided by the invention is mainly applied to the intersection canalization design.

Description

technical field [0001] The invention belongs to the technical field of channelization design at level intersections, and relates to a method for setting a separate left-turn lane dedicated to trucks at a signal-controlled intersection, and specifically relates to a method for setting a separate left-turn lane dedicated to trucks. Background technique [0002] Aiming at the level intersections between the ring roads and urban roads on the outskirts of the city, the ring road is the main channel for trucks to enter the expressway, and there will be a large number of trucks turning left on the urban arterial road to enter the ring road, and the types of trucks mainly include large Trucks, container trucks, trailers, etc. Compared with passenger cars, trucks have the characteristics of large volume, low speed and poor maneuverability. As the proportion of freight vehicles increases, the interference between passenger and freight vehicles will intensify, which will inevitably gr...
