摘要

Provided are in-vehicle terminal device and a traffic control system such that even in the event of a problem in the communication environment, interference between vehicles can be minimized and work efficiency can be improved. The present invention is provided with a terminal-side control device 761 that performs processing for sending a travel instruction to the driver of the host vehicle on the basis of a travel permission section assigned thereto by a control server 31. The terminal-side control device 761 includes: a remaining distance calculation part 761a that calculates a travel permission remaining distance on the basis of the current position of the host vehicle acquired from a position calculation device 79 and the travel permission section; an upper limit speed calculation part 761b that calculates an upper limit speed of the host vehicle in the travel permission section on the basis of the travel permission remaining distance calculated by the remaining distance calculation part 761a; and a display control part 761c that causes a terminal-side display device 763 to output and present to the driver the upper limit speed calculated by the upper limit speed calculation part 761b and predetermined warning information corresponding to the upper limit speed.
