Step 1: Understanding the Concept:
The question asks to identify the most suitable location for a school bus stop from four given options, keeping in mind traffic rules, safety of children, and practical considerations in the Indian context.
Step 2: Key Formula or Approach:
We must evaluate each location based on the following criteria:
1. Child Safety: Minimizing the need for children to cross the road or walk in traffic. The location should not create blind spots for other drivers.
2. Traffic Flow: The bus stop should cause minimal disruption to the flow of traffic on the one-way road.
3. Use of Infrastructure: The location should encourage the use of existing safety features like the zebra crossing.
Step 3: Detailed Explanation:
Let's analyze the given options based on the diagram:
The road is one-way, with traffic flowing from left to right.
The school is on the upper side of the road, and a playground is on the lower side.
A zebra crossing is provided for pedestrians.
Evaluation of Locations:
Location A: This is on the same side as the school but \textit{before} the zebra crossing. A bus stopping here would block the view of the zebra crossing for drivers approaching from behind, creating a dangerous situation for children crossing. This is not an ideal location.
Location B: This is on the same side as the school and \textit{after} the zebra crossing. This is a relatively safe option as children can get off the bus and directly enter the school without crossing the road. However, placing a bus stop very close to the school gate can lead to congestion of both people and vehicles at the entrance.
Location C: This is on the opposite side of the road (playground side) and \textit{before} the zebra crossing. This requires children to cross the road to get to school. A bus stopping here would also obscure the view of the zebra crossing. This is an unsafe option.
Location D: This is on the opposite side of the road and \textit{after} the zebra crossing. This location requires children to cross the road. However, it has some specific advantages from a traffic management perspective:
Visibility: The bus stops after the zebra crossing, so it does not obstruct the view of the crossing for other drivers.
Regulated Crossing: It compels all children to walk back to the designated zebra crossing to cross the road. This channels pedestrian traffic to a single, safe point which can be monitored (e.g., by a traffic warden).
Reduced Congestion: It prevents the formation of a crowd and traffic jam directly in front of the school gate.
In urban planning, especially in a context where disciplined use of crossings is encouraged for safety, this option is often considered. It prioritizes organized pedestrian movement over the convenience of a same-side drop-off.
Step 4: Final Answer:
Considering the benefits of ensuring the zebra crossing is used and preventing congestion at the school gate, location D is the most plausible answer in a planned traffic context.
