Hello, Can I get an answer for this question please?
After mall opening, the traffic volume (demand) in a certain road section (6-lane divided highway)at the peak hour is forecasted to be 5200vph. An accident blocks 1 lane of the highway. It took15 minutes till the accident is cleared and capacity is fully restored. Use the following speeddensity relationship: u=112.81-1.75k (u is speed in kph and k is density in vpk/lane) to answerthe following questions:a.) Determine the free-flowing speedb.) Compute for the shockwave between the free-flow state and the state where there iscapacity reduction due to accident.c.) Compute for the shockwave between state when there is capacity reduction due toaccident and the state where vehicles flow with full section capacitySHOW FULL SOLUTION

II. Find the number of TUs needed for the service as well as the terminal times. The service provider needs to reduce the number of transit units by two through skip- stop operations while maintaining the same service headway on Major stations. Determine number of stops that can be operated as skip stops to satisfy the ervice provider's needs.

A bus route has stops at every intersection, 200 m apart. The speed of traffic and of the buses except for their stopping at bus stops is 30 km/h, but for every stop, buses lose a total of ts=20 seconds. Passengers are uniformly distributed along the route and walk to/from its stops at a speed of Vw= 4.8 km/h. a. How would a passenger's total travel time (consider only access to stops and travel on buses) change if every other stop was abandoned (i.e., the spacing between stops was increased from 200 m to 400 meters, if the average trip length on the line is: i) 4 km; ii) 6 km; and iii) 8 km? b. For what passenger trip length Lp will the total travel time remain the same?
