A new at-grade transportation network without conflict movement at intersections
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.
期刊介绍:
Transportmetrica B is an international journal that aims to bring together contributions of advanced research in understanding and practical experience in handling the dynamic aspects of transport systems and behavior, and hence the sub-title is set as “Transport Dynamics”.
Transport dynamics can be considered from various scales and scopes ranging from dynamics in traffic flow, travel behavior (e.g. learning process), logistics, transport policy, to traffic control. Thus, the journal welcomes research papers that address transport dynamics from a broad perspective, ranging from theoretical studies to empirical analysis of transport systems or behavior based on actual data.
The scope of Transportmetrica B includes, but is not limited to, the following: dynamic traffic assignment, dynamic transit assignment, dynamic activity-based modeling, applications of system dynamics in transport planning, logistics planning and optimization, traffic flow analysis, dynamic programming in transport modeling and optimization, traffic control, land-use and transport dynamics, day-to-day learning process (model and behavioral studies), time-series analysis of transport data and demand, traffic emission modeling, time-dependent transport policy analysis, transportation network reliability and vulnerability, simulation of traffic system and travel behavior, longitudinal analysis of traveler behavior, etc.
