An automobile with projected area 2.6 m2 is running on a road with speed of 120 km per hour. The mass density and the kinematic viscosity of air are 1.2 kg/m3 and 1.5 10 5 m2 / s, respectively. The drag coefficient is 0.30. The drag force on the automobile is
The following statements are made related to the lengths of turning lanes at signalized intersections : (i) 1.5 times the average number of vehicles (by vehicle type) that would store in turning lane per cycle during the peak hour (ii) 2 times the average number of vehicles (by vehicle type) that would store in turning lane per cycle during the peak hour (iii) Average number of vehicles (by vehicle type) that would store in the adjacent through lane per cycle during the peak hour (iv) Average number of vehicles (by vehicle type) that would store in all lanes per cycle during the peak hour As per the IRC recommendations, the correct choice for design length of storage lanes is
A two-lane urban road with one-way traffic has a maximum capacity of 1800 vehicles/hour. Under the jam condition, the average length occupied by the vehicles is 5.0 m. The speed versus density relationship is linear. For a traffic volume of 1000 vehicles/hour, the density (in vehicles/km) is
The speed-density (u-k) relationship on a single lane road with unidirectional flow is u = 70 0.7 k, where u is in km/hr and k is in veh/km. The capacity of the road (in veh/hr) is _______
Two major roads with two lanes each are crossing in an urban area to form an uncontrolled intersection. The number of conflict points when both roads are one-way is "X" and when both roads are two-way is "Y". The ratio of X to Y is
It was observed that 150 vehicles crossed a particular location of a highway in a duration of 30 minutes. Assuming that vehicle arrival follows a negative exponential distribution, find out the number of time headways greater than 5 seconds in the above observation ?
An automobile with projected area 2.6 m
On a section of a highway the speed-density relationship is linear and is
It is proposed to widen and strengthen an existing 2-lane NH section as a divided highway. The existing traffic in one direction is 2500 commercial vehicles (CV) per day. The construction will take 1 year. The design CBR of soil subgrade is found to be 4 percent. Given: traffic growth rate for CV = 8 percent, vehicle damage factor = 3.5 (standard axles per CV), design life = 10 years and traffic distribution factor = 0.75. The cumulative standard axles (msa) computed are
A roundabout is provided with an average entry width of 8.4 m, width of weaving section as 14 m and length of the weaving section between channelizing islands as 35 m. The crossing traffic and total traffic on the weaving section are 1000 and 2000 PCU per hour respectively. The nearest rounded capacity of the roundabout (in PCU per hour is)
