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/s²], driver

Use Bishop's definition of effective stress for the silt layer, assuming x =S.. Assume a value of G. = 2.65 and that the gravimetric water content of the silt below the water table is 20%. Use the SWRC for the silt from the figure below. Assume that the air pressure is equal to atmospheric pressure (i.e., zero).

The height of the parapet above the roof is 2 feet. The walls are to be constructed of 8-inch CMU and are to be fully grouted. The building is assigned to SDC D, and therefore, the walls have to be special RM shear walls according to TMS 402. There are 6 shear walls to resist the lateral seismic force along one principal axis of the building and 4 shear walls along the other axis. The corner walls are flanged walls meeting the requirements in Sec. 5.2.3 of TMS 402-22. The columns carry only gravity loads and no lateral seismic forces. The floor and roof diaphragms are relatively flexible in out-of-plane bending compared to the in-plane flexural stiffness of the walls, so that you can ignore the coupling moments and shear forces exerted by the diaphragms on the walls. However, the in-plane stiffness of the diagrams is high so that their planar deformation can be ignored.…arrow_forward

Assume a bus line with N stops, where the distance between stops is S. Free flow speed of the bus is v, with acceleration and deceleration, a. P passengers per stop are boarding and alighting, and the time needed for a passenger to board or alight is T seconds. What is the average speed of a bus? b. Following on part (a), assume the origins of passengers are spread uniformly along the bus route. The destination of all passengers is the last stop. The walking speed of passengers is u. Determine the average travel time (walking + in-vehicle) of passengers. c. Simplify the above equation when N is large enough (approximating N-1/2 by N-1). Consider now that you can decide on S, where you replace N=L/S (L is the length of the route). Find the value of S that minimises the travelling time of the passengers. d. In the same setting as (c), assume that some passengers do not go to the terminal but alight before. Explain if your answer from (c) would increase or decrease and why. If you need…arrow_forward
- The minimum cycle length for an intersection is determined to be 95 seconds. The critical lane group flow ratios were calculated as 0.235, 0.25, 0.17, and 0.125, respectively. Assuming 5 seconds lost per phase, determine which X was used.arrow_forwardA four-phase traffic signal has critical lane group flow ratios of 0.250, 0.150, 0.225 and 0.125.
