ABSTRACT
A fusion framework for urban traffic control and route guidance (UTCGS) based on the Cyber-Physical System (CPS) was proposed. This framework involves computation, communication, control and physical components that facilitate the enhancement of the fusion degree of the Urban Traffic Flow Guidance System (UTFGS) and the Urban Traffic Control System (UTCS). The proposed framework focuses on the technical analysis of the feasibility of the depth fusion of both systems and provides a theoretical basis for the implementation of urban traffic control and route guidance fusion in intelligent traffic systems. The traffic system spatial-temporal congestion is mainly caused by three conditions, such as vehicle space distribution and vehicle time distribution are not consistent, vehicle space distribution is inconsistent and vehicle time distribution is inconsistent. The gap between vehicle space distribution and vehicle time distribution indicates that the different spatial-temporal distributions are divided into three categories. The formation mechanism of space factor congestion is similar to the formation mechanism of time factor congestion. For example, in vehicle space congestion, vehicle space distribution imbalance or space network structure imbalance will lead to congestion. Based on the congestion formation mechanism analysis, corresponding fusion method were proposed.
