7337 ABSTRACT Traffic delays at priority type intersections R. ASHWORTH, MEng, PhD, MICE, AMlnatHE' This Paper is concerned with the calculation of delays to minor road vehicles at a priority type intersection. Consideration is given to the question of drivers having a distribution of critical acceptance gaps and a semi-empirical delay relationship is established which can be considered as a modified version of the formula originally proposed by Tanner for the case of all drivers having the same critical acceptance gap. Verification of the validity of this modified formula is obtained observations by of traffic delays at a priority type intersection on the outskirts of Liverpool...
