Q1) The project speed is 100 km/h on a divided state road with a vertical curve. The driver's transition reaction time is 2.0 seconds; the friction coefficient is 0.4. Accordingly, calculate the following: a) The slopes of g₁ and g2. b) The vertical curve length (L).

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
