A new at-grade transportation network without conflict movement at intersections

Abstract

This research aims to propose a new form of transportation network, the Chet network, to facilitate vehicular flow within a new area of built environment. One- and two-way links are uniquely arranged to form hexagonal blocks, such that vehicles can move from one place to another without facing any conflict in movement at intersections. The proposed network maintains a low-cost at-grade infrastructure, but does not require stop signs or traffic signals, which can delay traffic. Hence, the mobility performance of the proposed network is expected to be better than that of a traditional grid network. A proof-of-concept is conducted through microscopic traffic simulation, in order to take into account individual driving behaviors. The numerical results are very impressive. Discussions regarding practical issues are also provided. Nevertheless, the Chet network is original. It can be considered as an innovative design that could change the way of how people live and travel.
