- 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/hData obtained from aerial photography showed six vehicles on a 200 metre long section of road. Traffic data collected at the same time indicated an average time headway of 4 sec. Determine (a) the density on the highway, (b) the flow on the road, and (c) the space mean speed.From the following data of a freeway surveillance, there are 4 vehicles counted for a length of 200 m and the following distances each had travelled when observed on the photographs taken every 3 seconds apart. Compute the following:i. Density of flow in vehicles per km (vpk). ii. Space mean speed in kph. iii. Flow rate, in vehicles per hour. SHOW COMPLETE SOLUTION. NEED ASAP. THNAK YOU
- A traffic data has been collected on two points on a highway: Point A and Point B, 450m apart. Observations at Point A shows that five vehicles passed the location at intervals 5, 5, 3, and 3 sec respectively. The speed of the vehicles at point A are 61, 59, 70, 79, 55 km/hr respectively. Assume the speed is maintained until point B. What is the density, in veh/km.The median speed of vehicles on a highway segment during rush hour is 40 mph with Cv of 0.2. Assuming lognormal distribution, find the fraction of time the speed will fall below 10 mph? What about greater than 50 mph?A flow characteristic that is related to the density and obtained from speed data is occupancy. Data obtained from a 6-ft by 6-ft inductive loop detector is used to determine the traffic density. With an occupancy of 9.375%, determine the density, in vehicles per mile, for a mean vehicle length of 27 feet.
- Data from a 6ft by 6ft inductive loop detector collected during a 60 second interval indicates that the mean speed of traffic is 50mph among the 32 vehicles counted. Assume an average vehicle length of 19ft. Calculate a. The density, b. The occupancy, and C. The flow rate during this interval.A segment of a highway was designed for a free flow speed of 90 mph. At the time of observation along the segment, it was recorded that same segment was at its maximum flow. What is the average speed of vehicles at this instant?A section of highway is known to have a free-flow speed of 50mph and a capacity of 3600 veh/h. In a given hour, 2400 vehicles were counted at a specified point along this highway section. If the linear speed-density relationship (greensheild model) applies, what would you estimate the space-mean speed of these 2400 vehicles to be?
- Suppose you are noticing traffic in a single lane of an expressway at a particular area. The average headway is quantified as 4.2 seconds. The average spacing of successive vehicles is found as 38 meters. According to the findings, compute the average speed, flow, and density of this stream on the lane.This is a three-part question. Data obtained from aerial photography showed eight vehicles on an 800 ft-long section of road. Traffic data collected at the same time indicated an average time headway of 3.7 sec. Part A. Determine the density on the highway in vehicles per mile. Part B. Determine the flow on the road in vehicles per hour. Part C. Determine the space mean speed in mph.Subject : Transportation Engineering Give me right solution according to the question.. Please urgent please Free flow speed of a roadway section is 100 km/h and the capacity of the same section is 3000 veh/h. At a specific point along this roadway section, 2400 vehicles were observed in a predetermined hour. What can be the space-mean speed of these 2400 vehicles if a linear speed-density relationship is considered?
