6, Traffic Shockwave theory (15%) Vehicles approaching an signalized intersection are traveling at speed 40 miles per hour and the density is about 40 vehicle/miles/lane (vehicle arrival). The red light last about 40 sec. If the saturation flow is 1900 vehhr/lane with a density of 52 veh/miles/hour (queue discharging). and the jam density is 120 veh/mile lane, please determine: a. the queue length at the end of the red light: b. the maximum queue length: c. The time it takes...

A-1. An exclusive through lane discharges 10 vehicles in 20 seconds. In the same amount of time a mixed lef-and-through lane discharges 3 left turning vehicles and 4 through vehicles. The left-turn equivalent is: a. b. 2 c. 20 seconds d. 6.66 seconds e. 3.33 seconds A-2. Detectors, in actuated controller operations, measure time between vehicle actuations which is then compared to (circle one of the options below) to extend green time: a. Minimum...

4- Consider Problem 3. Calculate the new minimum pedestrian green time, assuming the effective crosswalk width is 6 ft and the maximum number of crossing pedestrians in any phase is 20. This is the problem 3 Two additional 12-ft through lanes are added to Vine Street, one lane in each direction. If the peak-hour traffic volumes are unchanged but the Vine Street left-turn saturation flow rates increase by 120 veh/h because of the added through lanes, what would the revised...

3- Consider the third example solved in the lecture videos. Two additional 12-ft through lanes are added to Vine Street (the street in the intersection of the first example solved in the lecture videos), one lane in each direction. If the peak-hour traffic volumes are unchanged but the Vine Street left-turn saturation flow rates increase by 120 veh/h because of the added through lanes, what would the revised effective green time, yellow time, and all-red time be for each phase?...

A six-lane freeway (three lanes in each direction) in rolling terrain has 10-ft lanes and obstructions 4 ft from the right edge of the pavement. There are 4 ramps within 6 miles. A directional peak-hour volume of 4500 veh/h is observed, with 1250 vehicles arriving in the highest 15-min flow rate period. The traffic stream contains 15% heavy vehicles. What is the density and the corresponding level of service (LOS) of the traffic stream? Do not use on the chart...

HDT Truck Company HDT Truck Company has been located in Crown Point, Indiana, since 1910. Its only products— large trucks—are built to individual customer specifications. The firm once produced automobiles but dropped out of the auto business in 1924. The firm nearly went out of business in the late 1930s, but by 1940 its fortunes were buoyed by receipt of several military contracts for tank retrievers—large-wheeled vehicles that can pull a disabled tank onto a low trailer and haul it...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
