Comprehensive Benefit Evaluation of Beijing ETC System

As one important application-oriented subsystem of ITS,electronic toll collection(ETC) system was established in various provinces one after another and put into large-scale applications.To scientifically assess the social and economic benefits of the ETC system is of great significance for guiding the development of the system.The effects and benefits of freeway ETC system were analyzed.An evaluation system including transportation performance,energy and environment,charging operation and traffic safety was established.Through field investigation,vehicle running track simulation and energy consumption test,the computational model of comprehensive benefit evaluation indexes was built.The suggested values of model parameters were determined.Through a comprehensive benefit evaluation of ETC system,the overall monetized benefit of ETC within the service years was given.Combined with Beijing ETC system development status and trend prediction,it is obtained that the cumulative monetized estimated result is 1.257 billion Yuan during the period of system operation.The conclusions can provide an important reference for other provinces to carry out the ETC system evaluation.
