A temporary diversion has been constructed on a highway of +4 percent gradient due to major repairs that are being undertaken on a bridge. The maximum speed allowed on the diversion is 10 mph. Determine the minimum distance from the diversion that a road sign should be located informing drivers of the temporary change on the highway.
- Maximum allowable speed on highway = 70 mph
- Letter height of road sign = 4 in.
- Coefficient of friction between tires and pavement = 0.2
- Perception-reaction time = 2.5 sec
Assume that a driver can read a road sign within his or her area of vision at a distance of 40 ft for each inch of letter height.
