Calculate the minimum passing sight distance required for a two-lane rural roadway that has a posted speed limit of 45 mi/h. The local traffic engineer conducted a speed study of the subject road and found the following: average speed of the passing vehicle was 47 mi/h with an average acceleration of 1.43 m/h/sec, and the average speed impeder vehicles was 40 mi/h. Write your step by step solutions.

Assume you are an observer standing at a point on a three lane race track. All vehicles in lane 1 are traveling at 50 mi/h, all vehicles in lane 2 are traveling at 65 mi/h, and all vehicles in lane 3 are traveling at 70 mi/h. There is a constant spacing of 0.25 mile. If you collect spot speed data for all vehicles that pass your observation point in one hour, what will the time-mean speed be for the traffic stream?
Considering linear relationship between density and speed, you are required to estimate the corresponding flow and speed values to densities of 20, 30, 40 60, and 70 veh/km. if the free flow speed is 110 km/hr and at the critical situation, is founded that are 110 vehicles on section of the road with length 2km, using the estimated values, draw a sketch showing the speed-flow-density relationships?
Assume you are an observer standing at a point along a three‐lane roadway. All vehicles in lane 1 are traveling at 30 mi/hr, all vehicles in lane 2 are traveling at 45 mi/hr, and all vehicles in lane 3 are traveling at 60 mi/hr. The spacing between vehicles in each lane is 0.5 mile. If you collect spot speed data for all vehicles as they cross your observation point for 2 hours, what will be the time‐mean speed and space‐mean speed for this traffic stream?

Assume you are an observer standing at a point along a three lane roadway. All vehicles in lane 1 are traveling at 50 km/h, all vehicles in lane 2 are traveling at 75 km/h, and all vehicles in lane 3 are traveling at 100 km/h. There is also a constant spacing of 0.8 kilometer between vehicles. If you collect spot speed data for all vehicles as they cross your observation point, for 30 minutes, what will be the time mean speed and space mean speed for this traffic stream?
Data obtained from aerial photography showed nine vehicles on a 720 ft-long section of road. Traffic data collected at the same time indicated an average time headway of 4.2 sec. Determine the following. (a) the density on the highway (in veh/mi) veh/mi (b) the flow on the road (in veh/h) veh/h (c) the space mean speed (in mi/h) mi/h
