A TIME-DEPENDENT APPROACH TO JUNCTION DELAYS

When demand at a junction is close to or above saturation and is varying with time, conventional steady-state delay formulae are inapplicable. The formulae presented in this paper extend previous work on a dynamic delay formulae to the case of time-dependent demand. A peak period is divided into a series of short intervals during each of which demand is considered to be stationary. By taking into account the mean queue length at the beginning and end of each interval, a representation of average delay is obtained which compares favourably both with more complex analytical formulae and with results of simulations.(a) /TRRL/
