| Abstract | The purpose of this research is to compare two new at-grade transportation networks that do not require traffic signals. The Chet network and the Eichler network are compared in the perspective of traffic mobility. The Chet network is a hexagonal network with one-way and two-way links uniquely arranged as the sides of hexagonal blocks. Eichler network is similar to a grid network but has a unique arrangement of one-way and two-way links to form several intersection layouts with specific turning movements where there are no conflicts. In previous researches, it was proved the Chet network has potential to improve traffic mobility when comparing to a typical grid network. In this research, instead of comparing with a typical grid network, the Chet network is compared with another unique network to avoid conflict movements at intersection; i.e., the Eichler network. A microscopic traffic simulator is used as a tool to compare the two networks by accounting for individual vehicle behaviors. The challenge is to come up with equivalent settings to fairly compare the two networks. 30 test scenarios were modeled and simulated by varying five network configurations and six levels of demand. Numerical results indicate advantages of the Chet network in term of mobility. Discussions on other perspectives are also provided and guide for future research. |
