Skids marks of 25m on the pavement (f=0.4) followed by skid marks of 50m on the gravel shoulder approaching the abutment (f=0.5). What was the initial speed of the vehicle?16. The 15 min traffic counts on cross roads E and F during peak hours are observed as 170 and 135 vehicles per lane respectivelyapproaching the intersection in the direction of heavier traffic flow. If the amber time required are 4 and 3 sec respectively for two roads based on approach speeds, design the signal timing by trial cycle method. Assume an average time headway of 2.5 sec during green phase.17. A car travelling at a speed of 32kmph decides to overtake another car infront and accelerates.
