Worked Solution & Example Answer:Examine the aerial photograph accompanying this paper - Leaving Cert Geography - Question i - 2008
Step 1
Locate two areas where traffic congestion can create problems
Answer
-
Area 1: Right Background - This area shows a busy intersection where multiple roads converge, leading to potential bottlenecks during peak traffic times.
-
Area 2: Left Center - In this vicinity, there are road works evident, which can restrict lane usage and cause delays for vehicles passing through.
Step 2
Select one area chosen in part (i) and using evidence from the photograph, explain why traffic congestion might occur at that location.
Answer
Selected Area: Right Background
In the Right Background area, the aerial photograph displays an intricate layout of roads. The main reasons for potential traffic congestion here include:
- High vehicle volume: During rush hours, the number of vehicles attempting to navigate this intersection exceeds the road's capacity, leading to longer waiting times.
- Traffic signals: If traffic lights are poorly timed or malfunctioning, they can exacerbate waiting periods, further contributing to congestion.
- Obstructions: Nearby buildings and roadside parking may limit the road width, reducing the effective space available for vehicles to maneuver.
Step 3
Examine in detail one possible solution to this traffic congestion.
Answer
One effective solution to mitigate traffic congestion at the Right Background intersection is the implementation of a roundabout.
Benefits of a Roundabout:
- Improved Traffic Flow: Roundabouts allow vehicles to keep moving rather than stop, reducing the likelihood of traffic buildup.
- Enhanced Safety: Collisions are less severe in roundabouts, as vehicles travel in the same direction, decreasing the potential for head-on impacts.
- Space Efficiency: A roundabout can accommodate more vehicles with less physical space than a traditional intersection, making it ideal for urban settings.
Implementation Considerations:
- Design: The roundabout should be designed to accommodate various vehicle types, including heavy trucks.
- Signage and Markings: Proper signage is crucial to ensure drivers understand how to navigate the roundabout effectively.
- Community Engagement: Involving local residents in the planning process is essential to address concerns and gain support.
