Research on the application of TACS signal system in medium traffic volume urban rail transit
Currently,most domestic urban rail transit signal systems adopt CBTC based on vehicle-ground communication technology,which has issues such as a large number of trackside equipment,heavy maintenance workload,and high fault rate.With the development of technology and the changing operational needs of domestic urban rail transit,TACS based on vehicle-vehicle communication technology has emerged.This article first introduces the architecture composition and functional characteristics of TACS,and makes a comparative analysis with CBTC to clarify the technical advantages of TACS.Second,combined with the demand for upgrading existing lines and the key points and challenges of signal system transformation,it puts forward the idea of implementing the TACS engineering application,and takes Wuhu rail transit line 2 as an example to describe in detail the engineering contents involved in transforming the existing CBTC of medium traffic volume urban rail transit into TACS and analyze the feasibility of implementing the transformation project.As the upgraded version of CBTC,the TACS system has broad application prospects in the future in the field of urban rail transit.
