The diagram outlines two possible sites (S1 and S2) for a supermarket in the town of Garlsdon. Overall, two sites differ significantly in location and accessibility, with S1 located in the countryside while S2 situated in the town centre, which is a pedestrian-only zone. It is also clear that the town has a roughly ring-like layout, with the town centre surrounded by residential areas in the middle and the countryside on the outermost edge. Turning to S1, it is positioned in the countryside to the northwest of the town and is accessible by both foot and car. A railway to its southwest and a main road to its northeast link the site to the housing areas and the town centre. This transportation system makes S1 particularly accessible to residents in the northwest part of the town and those who live in Hindon, a small town nearby. Furthermore, S1 has a much more pleasant environment, as it is far away from the industrial zones. By contrast, S2 is situated in the town centre. Notably, three main roads connect the central part to the adjacent towns: Gransdon (25 km away), Bransdon (16 km away) and Hindon (12 km away), while a railway that runs through the town also lies close to this site. This excellent transport network is likely to attract shoppers not only from the town itself but also from the surrounding towns. However, the nearby industrial area to the south may have some negative impacts, such as air pollution and noise.
