Question

As per IRC 11:1962, separate bicycle tracks may be provided when the peak hour ............. Which of the following statement(s) can be used to correctly fill in the blank? (P) Bicycle traffic is 400 bicycles/hour or more and the volume of motorized vehicles is 100–200 vehicles/hour.
(Q) Bicycle traffic is 100 bicycles/hour or more and the volume of motorized vehicles exceed 200 vehicles/hour.
(R) Bicycle traffic is 100–200 bicycles/hour and the volume of motorized vehicle is 100–200 vehicles/hour.

• A. Only P \& Q
• B. Only P \& R
• C. Only R
• D. P, Q \& R

Hint:

IRC recommends separate cycle tracks when either cycle volume is very high (≥400/hr) or moderate (≥100/hr) with heavy motor traffic (>200/hr).

Answer 1

The Correct Option is A

Step 1: IRC guidelines.
As per the Indian Roads Congress (IRC) 11:1962, separate cycle tracks are recommended if bicycle traffic is very high or there is high interaction between bicycles and motor vehicles.

Step 2: Checking statement (P).
When bicycle traffic is \( \geq 400 \, \text{bicycles/hour} \) and motorized vehicles are 100–200 vehicles/hour → justified for providing separate tracks. \[ P \ \text{is correct.} \]

Step 3: Checking statement (Q).
When bicycle traffic is \( \geq 100 \, \text{bicycles/hour} \) and motor vehicle traffic exceeds 200 vehicles/hour → conflict occurs, so separate tracks are required. \[ Q \ \text{is correct.} \]

Step 4: Checking statement (R).
If bicycle traffic is only 100–200 bicycles/hour and motor vehicles are also 100–200/hour, then interaction is not significant enough to justify a separate cycle track. \[ R \ \text{is incorrect.} \] Thus, only (P) and (Q) satisfy the IRC condition. \[ \boxed{\text{Only P \& Q are correct.}} \]
