Civil Analysis of highway section A portion of a four-lane multilane highway with a full median carries 2,600 vehicles per hour during peak hours in the busiest direction. In the traffic flow, there are 2% RVs and 14% trucks. The facility's regular users are mainly motorists. The segment under study is a mile-long, 3% sustained gradient. PHF equals 0.88. Field research has been done to establish that the facility's free-flow speed is 55.0 miles per hour. What degree of service will be provided during peak hours at this facility?

A temporary, 2 lane road is to be built connecting the 2 westbound lanes of Highway 1 near Tompkins, Saskatchewan with the parallel 2 eastbound lanes, 600 metres to the south (centreline to centreline). This temporary road is comprised of two equal circular, horizontal curves connected by a tangent section, which has a bearing of 045°. For the following data: radius of curvature=500m; maximum superelevation=0.04m/m; maximum side friction=0.12; lane width=3.70m. Find: i) the design speed of the curved sections and ii) the total length of the new pavement required

By assuming a linear speed-density relationship, the mean free flow speed in a highway lane equals 55 mph, and the jam density is observed to be 170 vpm. a. Plot the q-k-u curves (3 curves). b. Write down the speed-density and flow-density equations. c. Compute the maximum flow. d. Compute speeds and densities corresponding to a flow of 900 vph. e. Calculate average headway, gaps, clearance, and spacing at maximum flow and at jam density.
