The invention relates to a
system and method for guiding urban railway traffic passenger flow based on last
bus time, and belongs to the technical field of urban railway traffic guidance devices and methods. The
system comprises a man-
machine interaction subsystem, a path reachable range search subsystem, a
reachability display subsystem, an active stepping subsystem and the like. The
current time and the current
station are used as known conditions through the active stepping subsystem, the
system carries out calculation and search, and the
reachability of the
station on a whole road network at the time is obtained and is displayed on the
reachability display subsystem. Passengers input query conditions through the man-
machine interaction subsystem, calculation is carried out through the system, and a result is displayed. The system and method meet the requirement for acquiring travel information which does not have network query conditions or has the network query conditions and ambiguous destinations. Reachable stations
closet to the destinations are provided for unreachable paths with last buses missed. The scheme that the passenger must go out at latest for reaching the destinations is provided. The real-
time path network range which the passengers can reach by starting from a certain
station in the
path network at
specific time is inquired or actively distributed.
