Twelve vehicles are observed in a 400 m section of the extension of SCTEX. Average time of headway is4 seconds. Determine the space mean speed.QUESTION 3 a) Road accident 'black spots' are locations that attract more accidents by comparison with other similar locations on the road system. Speed has been identified as a key risk factor in road traffic injuries at 'black spots' influencing both the risk of a road crash as well as the severity of the injuries from the crash. Interpret FIVE (5) benefits resulting from a spot speed study at the 'black spots' location conducted during Malaysia's festival season at KM399.8 of North-South Expressway. (CO1-PO3)(C3)

- 32. An industrial park consists of 16 buildings. The corporations in the park are sharing the cost of construction and maintenance for a new first-aid center. Because of the park's layout, distances between buildings are most closely approximated by a rec- tilinear distance measure. Weights for the buildings are determined based on the frequency of accidents. Find the optimal location of the first-aid center to minimize the weighted sum of the rectilinear distances to the 16 buildings.

If you don't know the solution please leave it but don't waste my question. Wha iI'm asking Read the question carefully. A curved segment of an existing road has a radius of 180 m, which restricts the posted speed limit for that segment to 75% of the speed limit of the road. If this segment of the road is to be improved so that the posted speed limit is that of the rest of the road, determine the radius of the improved segment. The maximum superelevation allowed is 8%.
