基于单向二分路的综合开发模式探索

城市不断发展,交通环境却每况愈下。通过对现有多种交通组织方式和用地开发模式进行梳理,寻找标本兼治缓解交通拥堵的模式,即单向二分路综合开发模式。该模式的特点有:道路系统为小地块、密路网、结合单向二分路模式;开发模式采用TOD模式结合城市综合体开发;交通流组织模式为主干路建设BRT系统。结合实际案例对比不同容积率和商住比情况下该模式道路承载力大小;模拟主干路在该模式与传统模式下通行能力优劣;对该模式与传统模式道路主要指标差异进行比较。通过与传统路网进行比较,显示出这一模式的优越性。

Comprehensive Development Based on One-Way Couplet

As the cities are experiencing expansion, they have been suffering an even worse traffic conges-tion. Through a review on a variety of existing types of transportation organizations and land development modes, this paper makes an attempt to use one-way couplet mode for easing traffic congestion. A couple of characteristics of such the mode are highlighted as follows:1) the roadway network is patched, dense, and featuring in one-way binary network; 2) the development pattern is more suitable to implementation of TOD with HOPSCA;and 3) BRT system is highly recommended in arterial roadways. The case study is ad-opted to compare network capacity of the traditional mode and the new mode in case of different plot ra-tios and commercial-residential rate. The traffic capacity of arterial roadways in the traditional mode and the new mode are simulated. The difference of roadway indices between the two modes are compared. The results show that the new mode shows superiority over the traditional mode.
