Match the following lists :
| List-I (Median widths at intersections) | List-II (Key features) |
|---|---|
| P.Four feet or wider | 1.Provides a pedestrian refuge and room for a dual left-turn bay |
| Q.Twenty-eight feet or wider | 2.Provides a pedestrian refuge and room for a left-turn bay |
| R.Sixteen feet or wider | 3.Provides a pedestrian refuge |
| S.Twenty feet or wider | 4.Provides refuge for a crossing passenger car |
Select the correct answer using the code given below :
- A4 1 2 3
- B3 1 2 4Correct
- C3 4 2 1
- D2 3 4 1
Solution
Concept
Median width and its function at intersections
Step-by-step solution
1. 4 ft or wider: pedestrian refuge → 3. 2. 28 ft or wider: pedestrian refuge plus a dual left-turn bay → 1. 3. 16 ft or wider: pedestrian refuge plus a left-turn bay → 2. 4. 20 ft or wider: refuge for a crossing passenger car → 4.
Explanation
Wider medians provide more functions, from a pedestrian refuge to a dual turn bay.
Why the other options are wrong
The other codes assign smaller functions to the widest median.
Shortcut
Width increases: refuge → left-turn bay → dual bay.
Correct answer: B) 3 1 2 4
