Abstract
Traffic congestion in metropolitan areas all over the world has become a critical issue that governments mustdeal with effectively. Traffic congestion during rush hours causes vehicle drivers to arrive late at their destinations,resulting in significant economic losses. Although researchers have proposed solutions to the traffic congestionproblem, little research work has presented a joint route and charging planning strategy for electric vehicles(EVs) that alleviates traffic congestion problems simultaneously. Accordingly, a congestion-preventing route and charging planning mechanism for EVs is proposed in this work to tackle the complicated route and charging optimizationproblems of EVs. The route and charging planning proposed in this work analyzes the information providedby EVs, the charging points, and road traffic information simultaneously, and mediates the traffic jammingby means of a route and charging reservation mechanism. Possible occurrence of traffic congestion is detectedin advance and traffic regulation is carried out by allocating an elastic range to the traveling period for late-bookingEVs, to avoid moving during rush hours. EV owners are also encouraged to provide rideshare services forlate-booking EV users during rush hours. The simulation results reveal that the proposed work can satisfy thepreferred route and charging demands of EV users and alleviate traffic congestion effectively.

We contrast the performance of three algorithms, including the proposed congestion control mechanism (GC), proposed congestion control plus. It can be observed from the recent literature that little research work has presented congestion-preventing route and charging planning mechanisms for EVs
Summary
Due to recent rapid urbanization, road traffic congestion in many metropolitan areas in the world has been deteriorating for years. A vehicle navigation system provides drivers with options for alternative routes based on historical and real-time traffic information, this does not ease traffic congestion owing to the vast number of vehicles navigating during rush hours. Most schemes presented in research work wait until vehicle drivers have nearly arrived at congested spots before taking action to alleviate congestion, based on updated real-time congestion information. To the best of our knowledge, little research work in the literature has presented route and charging planning for EVs that focuses on the traffic congestion prevention issue. The simulation results reveal that the proposed work can satisfy the preferred route and charging demand of EVs and solve the traffic congestion problem effectively.
