The consolidated data of a spot speed study for a certain stretch of a highway is given in the table. Speed range (kmph) | Number of observations 0 - 10 | 7 10 - 20 | 31 20 - 30 |...

The vehicle count obtained in every 10 minute interval of a traffic volume survey done in peak one hour is given below. Time Interval (in minutes) | Vehicle Count ---|--- 0 – 10 |...

The vehicle count obtained in every 10 minute interval of a traffic volume survey done in peak one hour is given below. Time Interval (in minutes) Vehicle Count 0 - 10 10 10 - 20 1...

A single-lane highway has a traffic density of 40 vehicles km. If the time-mean speed and space-mean speed are 40 kmph and 30 kmph, respectively, the average headway (in seconds) b...

A signalized intersection operates in two phases. The lost time is 3 seconds per phase. The maximum ratios of approach flow to saturation flow for the two phases are 0.37 and 0.40....

Vehicular arrival at an isolated intersection follows the Poisson distribution. The mean vehicular arrival rate is 2 vehicle per minute. The probability (round off to two decimal p...

Spot speeds of vehicles observed at a point on a highway are 40, 55, 60, 65 and 80 km/h. The space-mean speed (in km/h, round off to two decimal places) of the observed vehicles is...

Traffic volume count has been collected on a 2-lane road section which needs upgradation due to severe traffic flow condition. Maximum service flow rate per lane is observed as 128...

The uniform arrival and uniform service rates observed on an approach road to a signalized intersection are 20 and 50 vehicles/minute, respectively. For this signal, the red time i...

The safety within a roundabout and the efficiency of a roundabout can be increased, respectively. by

The queue length (in number of vehicles) versus time (in seconds) plot for an approach to a signalized intersection with the cycle length of 96 seconds is shown in the figure (not...

The spot speeds (expressed in km/hr) observed at a road section are $$66, 62, 45, 79, 32, 51, 56, 60, 53$$ and $$49.$$ The median speed (expressed in km/hr) is __________.
