Problem 1 (50%) Develop a signal design and timing for the intersection shown in the figure below. In each case accommodate both vehicular and pedestrian movements. In general, use the following values for the problem: pedestrian walking speed = 1 [m/s], vehicle deceleration = 3 [m/s?], driver reaction time = 1.5 [s], length of vehicle = 6 [m], and level grade = 0. If you need to assume other variables and parameters to solve this problem clearly state that in your report and explain the reason. ; tat vane) Speed limit = 50 [km/h] Pedestrian = 15 per each crosswalk Crosswalk widths = 3 [m] Lane width = 4 [m] . 250 Saturation flow = 1800 [veh/h/lane] -* 1100 1100 t 200 70 80 ___ 900
