Webb1 sep. 2013 · This study presents a method that combines travel-time estimation and adaptive traffic signal control. The proposed method explores the concept of vehicle-to-infrastructure communication, through which real-time vehicle localisation data become available to traffic controllers. WebbPRODYN is an algorithm able to compute in real time the best signal settings with respect to the delay criterion for any flow demand in traffic networks.
WebbThe maximum total delay time decreases from 96.15 h to 83.77 h, as low as 12.9%. The maximum average vehicle stop time reduces from 1.81 to 1.65; the decrease rate is … Webb3 juli 2024 · Iii DSRC-Actuated Traffic Lights System Design.

Webb26 juni 2024 · The 1997 Indonesian Highway Capacity Manual (IHCM) is widely used to calculate signal timings for Fixed Time Signal Control (FTSC). Comparison between FTSC and Fuzzy Logic Traffic Signal Control (FLTSC) is claimed to be valid if the calculation of signal timings using the 1997 IHCM formula gives optimum fixed time settings.
