Name the traffic survey data, which is plotted by means of Desire lines

The Roman civilization is primarily based on which city planning pattern?

The linear speed-density (u-k) relationship on a single lane road with unidirectional flow is u = 70 – 0.7k, where u is in km/hr, k is in veh/km. The capacity of the road (in veh/hr) is ____. 

The overtaking sight distance of a vehicle on a two-way traffic road is 437.91 m. The reaction time of the driver is 2 s. Calculate the desirable length of the overtaking zone.

While designing a hill road with a ruling gradient of 6%, if a sharp horizontal curve of 50

m radius is encountered, the compensated gradient at the curve as per the Indian Roads Congress specifications should be

The speed-density relationship in a mid-block section of a highway follows the Greenshields's model. If the free flow speed is v, and the jam density is k,, the maximum flow observed on this section is

The overtaking sight distance of a vehicle travelling in a two-way traffic is 437.91 m. The acceleration of the overtaking vehicle is 0.9 m/s². Calculate the minimum length of the overtaking zone.

Average free flow speed and the jam density observed on a road stretch are 60 km/h and 120 vehicles/km, respectively. For a linear speed-density relationship, the maximum flow on the road stretch (rounded off to the nearest integer, in vehicles/h) is

Pradhan Mantri Gram Sadak Yojna (PMGSY), launched in the year 2000, aims to provide rural connectivity with all weather roads. It is proposed to connect the habitations in plain areas of population more than 500 persons by the year

Calculate the length of the transition curve using the rate of introduction of superelevation from the following data:

Design speed = 65 km/hr, pavement width including extra widening = 7.5 m. Allowable rate of introduction of superelevation is 1 in 150 and e = 0.07.
