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 using the usual notation (e.g. Right Background etc. …..).
Answer
In the aerial photograph, two areas are identifiable as potential traffic congestion sites:
- Right Background: This area features a major intersection where several roads converge, which can lead to bottlenecks during peak hours.
- Foreground Left Side: Here, a shopping center's entrance creates congestion as many vehicles enter and exit, compounding the existing traffic flow from the adjacent streets.
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
Focusing on the Right Background area: This section is characterized by multiple lanes merging into a single point, heightened by traffic from four different directions. As cars approach the intersection, some drivers may slow down to navigate or anticipate turns, contributing to delays. Additionally, the presence of pedestrians and cyclists increases the complexity of the traffic dynamics, further exacerbating congestion.
Step 3
Examine in detail one possible solution to this traffic congestion.
Answer
One effective solution to mitigate congestion in the Right Background area could be the implementation of a roundabout.
Benefits of a Roundabout:
- Continuous Flow: Vehicles would travel in a circular path, allowing them to enter and exit without stopping, reducing delays.
- Safety: Lower speeds within the roundabout can lead to fewer accidents compared to traditional intersections.
- Pedestrian Crossings: Designated pathways for pedestrians could be incorporated to enhance safety without significantly impeding vehicle flow.
Implementation Considerations:
The construction of a roundabout would require reallocating existing road space, but would ultimately improve traffic efficiency and safety in this congested area.
