Download Solution PDFCalculate the lag distance for design speed of 47 km/h for two-way traffic on a single-lane road (assume coefficient of friction as 0.38 and reaction time of driver as 2.5 seconds)
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFConcept:
Lag distance = 0.278 × V × tR
Where,
V = Speed in Kmph
tR = Reaction time in sec
Calculation:
Lag distance = 0.278 × 47 × 2.5 = 32.665
For two way traffic on a single lane lag distance = 2 × 32.665 = 65.33 m
