1. A developer wants to provide access to a new building from a driveway placed 1000 ft upstream of a busy intersection. He is concerned that queues developing during the red phase of the signal at the intersection will block access. If the speed on the approach averages 35 mi/h, the density is 50 veh/mi, and the red phase is 20 sec, determine if the driveway will be affected. Assume that the traffic flow has a jam density of 110 veh/mi and can be described by the Greenshields model

Answer True/False to the following: 1) A strong degree of uniformity in the design of traffic facilities guarantees uniform reactions from drivers. 2) The traffic signal warrant that several agencies do not recommend using is the Peak Hour Traffic Volume warrant. 3) It is reasonable to use a higher unit extension time value on an actuated signal approaches with higher speeds. 4) According to the Roundabout Design Guide volume-to-capacity ratio of 0.85 must be the threshold for acceptable operation at a roundabout entry.
Q3c. At a three leg (T) intersection, the two-way peak hour volume on the minor road is 500 veh/hr and that on the major road is 600 veh/hr. As a Traffic Engineer, what type of intersection control will you propose? What is the basis of your proposal?
Studies have shown that the traffic flow on a single-lane approach to a signalized intersection can be described by the Greenshields model. If the jam density on the approach is 130 veh/mi, determine the velocity of the stopping wave when the approach signal changes to red if the density on the approach is 45 veh/mi and the space mean speed is 40 mi/h. At the end of the red interval, what length of the approach upstream from the stop line will vehicles be affected if the red interval is 35 sec?

A signalized intersection has two lane groups. The two WBT lanes (lane group #1) have a total volume of 863 pc/h and an average control delay of 24.5 seconds. The one WBL lane (lane group #2) has a volume of 203 pc/h and an average control delay of 36.5 seconds. What is the approach's LOS? Group of answer choices LOS A LOS D LOS C LOS B
plz, solve this problem, it is not graded question. Transportation Engineering-1 During a 70 sec period, a detector is occupied by vehicles for the following times: 0.31, 0.39, 0.41, 0.35, and 0.53 sec. Estimate the values of flow (q), density (k) and speed (v). Assume that the loop detector is 10 ft and that that the average length of the vehicle is 20 ft.
In a given instant, there were 2400 vehicles counted at a specific point along the portion of the TPLEX. The highway was designed to have a capacity of 3000 veh/hr with a free-flow speed of 60 kph. Compute the maximum value of the jam density in veh/km that could possibly occur during heavy traffic assuming linear speed-density relationship applies.
TRANSPORTATION ENGINEERING-TRAFFIC SIGNALS" Recent analysis at an approach to pre-time signalized intersection indicate that the volume-to-capacity ratio (v/c) is 0.8, htat saturation flow rate (s) is 1600 vehicles/hour, and the effective green time is 50 seconds. If the average delay, assuming D/D/1 is 11.25 seconds per vehicle, determine the arrival flow rate (vehicles/hour) and the cycle length.
A freeway traffic stream was observed to have a density of 22.0 veh/mi/ln when the mean speed was 55.0 mi/h. On another occasion at the same location, the jam density was found to be 132 veh/mi/ln. Assume Greenshields' model of traffic flow applies. The optimum speed (in mi/h) is: a) 22.0 b) 33.0 c) 55.0 d) 66.0 e) None of he above
There are 3 vehicles observed in a 100 m section of McArthur highway. If the average time headway is 4 sec., compute the space mean speed of the vehicles in kph. thank you
A developer has applied for a construction permit to build a supermarket at the southeast cornerof an intersection that is formed by a four-lane divided highway in the east-west direction and atwo-lane road in the north-south direction. Traffic on the two-lane road is controlled by a stop signat the intersection. The speed limit on the four-lane highway is 88 km/h. using the sight trianglerequirements at the intersection (Case B1), determine whether permission should be given for theconstruction if the following conditions exist. Provide a diagram for your solution.Major road lane width = 3.6 mMinor road lane width = 3.3 mMedian lane = 2.8 mDesign vehicle is a passenger carApproach grade = 2%Maximum feasible distance building from the center of the nearest lane of four-lane road = 5.4 mMaximum feasible distance building from the center of the nearest lane of two-lane road = 16.5 m
Subject: transportation engineering Read the question carefully and give me right solution according to the question. A signal has four phases, where the critical lane group flow ratios are 0.115, 0.204, 0.099, and 0.248. If the lost time per phase is 6 seconds and the critical intersection v/c ratio is 0.88, calculate the minimum cycle length and the phase effective green times such that the lane group v/c ratios are equal.
