Abstract:

针对驾驶员在快速路下错出口匝道,未能第一时间到达理想的地面道路等情况,对城市快速路指路系统进行一系列的优化设计,最大限度地发挥指路系统的作用。同时,以宁波北外环快速路为例,将设计理念运用于实践。经过优化设计后的指路系统为车辆驾驶员提供全面准确的道路信息,引导车辆高效出行,进而有效缓解地面道路的交通压力。
According to the situation that drivers pick wrong off-ramps on the expressways and fail to reach the perfect ground roads in the first time, the paper takes a series of optimization on the guiding system of urban expressways in order to make it work at maximum limit. At the same time, illustrated by the example of Ningbo north external ring, this paper takes design concepts into practice. The optimized guiding system offers overall and accurate road information, guides vehicles to trip efficiently, and effectively mitigates traffic pressure of ground roads.
