In the study on the reliability of link travel time

the delay of intersection queue is set up with fixed delay value

and the dynamic analysis of the intersection delay under the condition of stochastic road network is lacking. Aiming at the time-varying road network

according to the operational characteristics of traffic flow

considering the interaction of passengers and traffic

considering the mutual influence of vehicle queuing

signal phase

and traffic speed

stochastic dynamic link travel time reliability under different road service level can be fixed. The results show that the travel time with stochastic dynamic intersection delay is highly reliable.
