some transport problem

Consider a two-way signalized intersection comprising a single-lane approach (Approach 1) and a two-lane approach (Approach 2). Assume that Approach 1 only serves cars and Approach 2 serves both cars and buses. Arrival flow of Approach 1 is denoted by 91, and Approach 2 on average observes 9c2 and 9b2 flows for cars and buses, respectively. Moreover, assume that the saturation flow and loss time of Approach i-(1,2)) are 9 and 2, respectively. Given that the intersection is undersaturated with cycle time of C: 1. Determine the total vehicle delay and total passenger delay at the intersection, given that on average each car carries ne and each bus carries no 2. What is the minimum green time of each phase? 3. What is the optimum green time of each phase to minimize the total passenger delay at the intersection. Formulate the optimization problems and assume the constraints are satisfied Consider a two-way signalized intersection comprising a single-lane approach (Approach 1) and a two-lane approach (Approach 2).
