Phase transitions in dual-lane traffic model based on the continuous historical evolution message effect under V2X environment

Abstract

Connected vehicles can gain the traffic information through vehicle to everything (V2X) communication technology, which contributes to dredging the running cars on congested roads in the traffic network. Additionally, the historical evolution process of traffic flow may play more and more contributions in traffic cyber physical systems (T-CPS) under V2X environment. Consequently, we in this manuscript come up with an innovative lattice hydrodynamic model based on the continuous historical evolution message (CHEM) effect on two lanes under V2X environment. To investigate the CHEM effect in traffic congestion, theoretical analysis and numerical simulation experiments have been executed to reveal traffic dynamics evolution process. Through simulations, traffic stability is strengthened by amplifying the sensitivity coefficient of the CHEM effect and the limited memory duration number (L≤3). Fortunately, the results imply that the CHEM effect can prominently improve the stability of traffic flow, which verifies that the CHEM effect is of great significance and value in lattice hydrodynamic model during traffic dynamics evolution process.
