1. Historical influence: Many cities have a long history and the center location of their CBD may have been established during its early development. For example, cities that were founded in a port area would have the CBD located near the port. This is because trade and commerce were the main activities that took place in the port, making it a strategic location for businesses. In other instances, the center location of the CBD may have been determined by geographical factors such as the presence of rivers or mountains.
2. Transportation: The availability of transportation has a significant influence on the location of a CBD. Industries and businesses located in the CBD need to have easy access to transportation for the movement of goods and customers. In cities where highways or railroads were built in the early stages of their development, the CBD would be located near these transportation routes. This is because businesses that are located near transportation hubs have a competitive advantage over those that are not. Customers and suppliers can easily access businesses located near transportation routes, and this increases their chances of success.
