The accessibility of locations is an indicator when assessing or evaluating mobility concepts. Therefore, accessibility analysis is an important instrument in transport planning, provision of public services, and location planning, evaluation, and optimization.
There are different indicators that define accessibility, depending on the use case. For example, to analyze the accessibility of a planned kindergarten, it is more relevant to measure pedestrian accessibility for children in the vicinity. But when planning a logistics distribution center, it is more important to measure accessibility for trucks or for the recipients of the goods.
When the metrics of an accessibility analysis are visualized, planners get an additional perspective for considering connectivity, especially for biking, walking, and transit. This helps them understand the transportation situation.
Accessibility data with high spatial resolution clearly show areas where mobility provision does not match mobility needs, e.g., which are underserved by public transport. As a result, it is possible to quantify the improvements and investments needed.
By analyzing land use, road infrastructure, traffic stress, and transit schedules, stakeholders can analyze the mobility networks and how they enable people to travel to various destinations. This gives planners an understanding of what works, and of barriers to better connectivity.
