Given a four-legged pre-timed signalized intersection with one exclusive left turn lane, one through lane and one through/right lane on each approach (all approach and receiving lanes are 12 ft. and there is a 4-foot raised median separating the left turns from the opposing traffic lane), a 35 mph speed limit on all approaches, and the following traffic characteristics - Peak Hour Volumes EB WB NB SB Left 107 134 88 106 Through 599 653 432 487 Right 142 135 108 112 PHF 0.9 0.9 0.9 0.9 Arrival Type 4 4 3 3 Other input data - 3% heavy vehicles, no parking, no buses, no bikes or pedestrians, level grade on all approaches, in a non-CBD area. 1. Determine the appropriate yellow and all-red interval to use for each phase. Assume a 10 ft/sec2 deceleration rate, a one second reaction time, and a 20 ft. vehicle length. Round up yellow and all-red times to the nearest ½ second. 2. Assuming protected-only left turns, manually calculate the saturation flow rates for all lane groups. For the exclusive through and through-right lanes, assume the through movements are distributed to equalize the flow ratios. 3. Develop a protected-only left turn phasing plan that minimizes sum of critical v/s. 4. Estimate the optimal cycle length using the HCM Method with Xc = 0.9 and based on the HCM lost time/extension of effective green assumption. Round the estimated optimal cycle length up to the nearest 5 seconds. 5. Calculate all interval timings (critical and non-critical phases) for the optimal (rounded) cycle length. 6. Develop the queue accumulation polygon for the westbound exclusive through lane group and calculate the total uniform delay and average uniform delay per vehicle. Calculate the incremental delay for the westbound exclusive through lane group and determine the lane group level of service.
a) Find the free-flow speed and jam density for this relationship b) Derive equations depicting the relationship between flow and density, and speed and flow. Plot the resulting curves. Show the values of free-flow speed, jam density, and capactiy..
A two post in ground car lift uses compressed air to force water under two aluminum pistons that move in unison (both pistons at same elevation) to raise and lower the vehicles.
What are the effects of water pollution on the components of the hydrologic cycle?
An obstruction is lodged in a 10-ft wide rectangular channel (n = 0.022) that has a botom slope of 0.005. The depth of the channel just upstream of the obstruction is 5.0 ft. If the flow rate is 325 cfs, what is the channel and flow classification
A W16 x 36 simply supported beam is 30 ft long and supports auniform dead load of 970 lb/ft, a roof live load of 240 lb/ft and asnow load of 270 lb/ft. Is this beam adequate to support the load? Please show the calculations.
