total stopping distance (m) for speed limits of 103kph and 59kph.   Round your answer to 3 decimal places.

8. (15 points) Calculate the "clearance period," the "yellow time," and the "all-red period" for a signalized intersection. Assume that the initial vehicle speed, intersection length, and vehicle length are 45 mi/h, 44 ft, and 22 ft, respectively. Also, deceleration rate is 10 ft/s and driver reaction time is 1 second.

A highway section has a grade of -2%, a school zone is operated for 30 minutes before and after school time, the posted speed during the school zone will be 25 km/hr. A new sign will be installed to aware drivers about the school zone with a flashing light. Find the proper distance from the school zone that the sign should be located in a meter. Knowing that the traffic stream has a posted speed of 80 km/hr and the driver can recognize 1 in. of sign letter from 20 ft. The engineer summary for a spot speed study shows that there is a lot of speed violation, that some drivers drive 10% higher than the posted speed. The sign has a height of 5 in. Use default vehicle deceleration. one decimal answer for example 00.0, just a ut of Jestion value. Answer Next page 254 AM ROOD ENG 4/13/2021 W ProBook 4540s

Determine the total stopping distance (ft) for a highway with a design speed limit of 50mph. Assume G = -0.39%. Round your answer to 3 decimal places.

Determine the total stopping distance (ft) for a highway with a design speed limit of 55mph. Assume G = 2.57%.   Round your answer to 3 decimal places.

None

Determine the difference between the required total stopping distance (ft) for speed limits of 72mph and 25mph. Round your answer to 3 decimal places.

27 …… is the average speed of all vehicles along a roadway as determined by the distance and the rünning times between two selected points. 1. Running speed 2. Posted speed 3. Operating speed 4. Design speed
