Access between vehicle entrances and urban roads is one of the most important factors considered to ensure the safety and efficiency of the road operation.The entrance is usually located away from intersections to reduce the interference on urban roads. However, in practice, there are still some entrances that are set close the intersection. Therefore, this study conducted the traffic operational analysis of a controlled entrance accessing the urban road with a signalized intersection. A field investigation of the eastern entrance of Zhengzhou University was conducted. Video cameras were used to obtain traffic operation data. Poisson probability distribution was then utilized to describe the vehicles\' arriving process at the entrance using the Chi-square test. M/M/1 queuing model was utilized to analyze the queue length and waiting time of vehicles before the entrance barrier. Impacts of factors including the traffic light timing and phasing, barrier serving time, the distance between the entrance and the intersection on the traffic operation were analyzed.
Keywords:controlled access; urban road; traffic impact; improvement measures
