| 摘要： | The Travel Time Prediction System (TIPS) is a portable, real-time, automated system that calculates
Travel times between different points in advance of and within a freeway work zone and displays diem to
motorists on changeable message signs. It collects real-time traffic flow data at 30 sec intervals using
several non-contact sensors, transmits the data by wireless communication to an on-site personal
computer, processes the data with a specially-develop intelligent software to obtain the estimated travel
time, and transmits die travel time information by wireless communication to changeable message signs
positioned at pre-determined locations al(»g die freeway section which in turn display the information to
the motorists. TIPS integrates several off-the-shelf equipment with the software and requires m i n i m al
human supervision during operation TIPS can display simple, easily-understood messages cm portable
changeable message signs, such as; MINUTES TO END OF WORK ZONE ” , or ” XX MINUTES
DELAY AHEAD ” where XX is calculated |
