Longdistance singlelane tunnels have many disadvantages, such as sight block of the
driver in a dark and wet environment, risk from multiple vehicles, and low
transportation efficiency. As a result, longdistance
tunnel wireless communication and positioning technology has been developed
using a vehicle autonomous avoidance algorithm, intelligent transportation
command system, and vehicle dispatching command terminal. The system provides
warnings for vehicles moving in the same or opposite directions, providing
collision avoidance warnings 20~35 s in advance when vehicles are moving in
opposite directions, and precise positioning and rear end collision prevention
notifications within the range of 50~200 m when vehicles are moving in the same
direction. The system reduces driving risk of trackless transport in longdistance singlelane tunnel, improves tunnel
construction efficiency, ensures the safe and efficient transportation of
materials at construction sites, and provides a foundation for smart technology
in construction site management.
