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.
According to Indian Roads Congress (IRC) 11:1962, separate cycle tracks are recommended if bicycle traffic is substantial or if there is significant interaction between bicycles and motorized vehicles.

Step 2: Statement (P) Evaluation.
A condition where bicycle traffic is ≥ 400 bicycles/hour and motorized vehicles are 100–200 vehicles/hour justifies the provision of separate tracks.

P is correct.

Step 3: Statement (Q) Evaluation.
When bicycle traffic is ≥ 100 bicycles/hour and motor vehicle traffic exceeds 200 vehicles/hour, a conflict arises, necessitating separate tracks.

Q is correct.

Step 4: Statement (R) Evaluation.
If bicycle traffic ranges from 100–200 bicycles/hour and motor vehicle traffic is also 100–200/hour, the interaction is not sufficiently high to warrant a separate cycle track.

R is incorrect.

Consequently, only statements (P) and (Q) align with the IRC conditions.

Only P & Q are correct.
