Question

Travel time and delay studies on a preselected section of a highway are conducted by

• A. Fast moving car method
• B. Enoscope
• C. Radar
• D. Traffic counters

Hint:

Important traffic studies:
• Fast moving car method $\rightarrow$ Travel time and delay study.
• Radar gun $\rightarrow$ Speed measurement.
• Traffic counter $\rightarrow$ Traffic volume count.

Answer 1

The Correct Option is A

Concept: Travel time and delay studies determine the average travel time, running time, stopped delay, and operational efficiency of a highway section. The most commonly adopted technique is the \[ \boxed{\text{Moving Observer (Floating/Fast Moving Car) Method}.} \] This method measures journey time while travelling with the traffic stream.

Step 1: Understand the moving car method. A test vehicle is driven along the selected highway section. The observer records:
• Journey time.
• Running time.
• Delay due to intersections and congestion.

Step 2: Identify the correct method. Hence, \[ \boxed{\text{Travel time and delay studies are conducted using the fast moving car method}.} \] Therefore, the correct option is \[ \boxed{(A)\;\text{Fast moving car method}.} \]
