To assess the potential of a petrol station, the surrounding commercial districts are usually divided into three levels.

The first level is the range close to the petrol station (1.0 km or 1.5 km)

It is the scope of the new design petrol station as the most convenient local petrol station to participate in the market competition. If there are no positive factors such as residential buildings, industrial areas, and traffic generators in this area, the expected sales of gas stations must be affected. This level of business district is the key to determining the sales of petrol stations.

The second level is the customer range (5 kilometers)

This area is the source of most of the sales of petrol stations. To better determine the overall potential of the area, it is necessary to conduct market and competitive analysis in the area.

The third level is the entire market/urban area (more than 5 kilometers)

If the area to be invested in is an urban area, it is necessary to analyze the supply and demand relationship of the entire market and the activities of competitors. Some key factors such as large supermarkets and transit roads should be considered in the analysis.
