Solution:

A well-designed signalized intersection is one in which the

crossing conflicts are increased

total delay is minimized

cycle time is equal to the sum of red and green times in all phases

cycle time is equal to the sum of red and yellow times in all phases

Solution:

The capacities of "one way 1.5 m wide sidewalk (persons per hour) and one way 2-lane urban road (PCU per hour, with no frontage access, no standing vehicles and very little cross traffic)" are respectively

1200 and 2400

1200 and 1500

1800 and 1200

1200 and 2000

Solution:

A traffic on a road has the following observations. Average spacing under jam conditions is observed as 5m. Free flow speed is observed as 90kmph, then the ratios of capacities of the stream using Green shield, underwood and Greenberg models is:-

1 : 1.47 : 1.47

1 : 2.36 : 1.47

1 : 1.47 : 2.36

2.36 : 1 : 1.47

Solution:

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

increasing the entry radius and increasing the exit radius

increasing the entry radius and decreasing the exit radius

decreasing the entry radius and increasing the exit radius

decreasing the entry radius and decreasing the exit radius

Solution:

A pre-timed four phase signal has critical lane flow rate for the first three phases as 200, 187 and 210 veh/hr with saturation flow rate of 1800 veh/hr/lane for all phases. The lost time is given as 4 seconds for each phase. If the cycle length is 60 seconds, the effective green time (in seconds) of the fourth phase is _________
