Vehicles travel at constant speeds on a one-lane one-way street between sections X and Y. An
observer located at point X observes the four vehicles passing point X during a period of 10
seconds. The speeds of the vehicles are measured as 45, 45, 40, and 30mph, respectively.
Calculate the average flow, density, time mean speed, and space mean speed.

- Write down the objectives of speed studies and what are the factors affecting the speed of vehicles?arrow_forwardA vehicle pulls out onto a single-lane highway that has a flow rate of 300 veh/h (Poisson distributed). The driver of the vehicle does not look for oncoming traffic. Road conditions and vehicle speeds on the highway are such that it takes 1.7 seconds for an oncoming vehicle to stop once the brakes are applied. Assuming a standard driver reaction time of 2.5 seconds, what is the probability that the vehicle pulling out will get in an accident with oncoming traffic?arrow_forwardAt an impaired driver checkpoint, the time required to conduct the impairment test varies (according to an exponential distribution) depending on the compliance of the driver, but takes 60 seconds on average. If an average of 30 vehicles per hour arrive (according to a Poisson distribution) at the checkpoint, determine the average time spent in the system in minutes/vehicle.

If the linear speed-density relationship applies, what was the space-mean speed of the vehicles during the hour of monitoring?arrow_forwardData on a traffic accident record on a certain intersection for the past 4 years has an accident rate of 9200 per million entering vehicles (MEV).

The student strikes the sign at a speed of 25 mi/h. If the student was traveling at 55 mi/h when the sign was first spotted, what was the student’s perception/reaction time?arrow_forwardTwo drivers each have a reaction time of 2.5 seconds. One is obeying a 90 km/h speed limit, and the other is travelling illegally at 108 km/h. How much distance will each of the drivers cover while perceiving/reaction to the need to stop, and what will the total stopping distance be for each driver (using practical stopping distance and assuming roadway grade g = -2.5%). Longitudinal friction coefficient (fi) can be calculated by the equation f = 1.0371 V-0.2729 where V vehicle speed in km/h.|arrow_forward
