作为替代小汽车出行的备选之一,骑车方式越来越深入美国交通决策领域,相应研究应运而生。1概要对一个以吸引尽可能多的人使用为目的的自行车路网而言,其最基本的属性应该是低交通压力网络的连通性——即为骑车者的O-D出行提供无需假借交通压力大得难以容忍的道路,且无需不必要绕道距离的可能路径。目标是研制低压力网络连通性的测量手段、评价与 As an alternative to the car travel alternative, cycling way more and more into the field of US transportation decision-making, the corresponding study came into being. 1 SUMMARY The most basic attribute of a bicycle network for the purpose of attracting as many people as possible is the connectivity of a low-traffic stress network - that is, there is no need for under-the-counter traffic pressure for rider OD travel A path that is too big to tolerate and does not require a possible path to detour distances. The goal is to develop low pressure network connectivity measurement methods, evaluation and
