Determine the density (in veh/mi) of a traffic stream comprised mainly of passenger cars, for which a 6-ft long detector measured an occupancy of 17%. Assume an average vehicle length of 18 ft. A. 37.4  B 41.3       C 49.9 D Insufficient information is provided. E None of the above

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?

Make a cumulative vehicle diagram and queue accumulation polygon based on the following field data collected from an approach at a signalized intersection, namely: 1. Cycle length = 72 seconds 2. Red interval = 30 seconds 3. Green interval = 42 seconds 4. Vehicle arival flow = 900 vehicles/hour %3D %3D 5. Saturation flow rate = 1800 vehicles/hour 6. Vehicle departures every 2 seconds

Given a freeway flow study at a certain highway. The speed- density relationship is described in the givenequation or relationship: V s = 58- 0.40k Determine the following:a. Free-flow speed and jam densityb. Derive the equation describing flow and speed.c. Derive the equation describing flow and density.d. Determine the capacity of highway
