Q: As per IRC, when designing pedestrian and traffic signals using approximate method for a two-phase system, the minimum initial period with pedestrian signal should NOT be less than.
  • A. 7 seconds
  • B. 6 seconds
  • C. 4 seconds
  • D. 9 seconds
Correct Answer: Option A - : As per IRC– The pedestrian green time required for the major roads is calculated based on walking speed of 1.2 m/sec and initial walk time of 7.0 second. • The cycle time is calculated after allowing amber time per 2.0 second each.
