Analysis on Link Travel Time Estimation considering Time Headway Based on Urban Road RFID Data by Jian Gu, Miaohua Li, Linghua Yu, Shun Li, Kejun Long

“…In this paper, the calculation method of the link travel time is firstly analysed in the continuous traffic flow by using the detection data collected when vehicles pass through urban links, and a theoretical derivation formula for estimating link travel time is proposed by considering the typical vehicle travel time and the time headway deviation upstream and downstream of the links as the main parameters. …”
