Background
According to the authors, the main motivation to develop an accessibility instrument can be roughly divided in three categories: policy and planning support, scientific enquiry, or a combination of the two. 10 can be placed in the first category, 4 in the second, and 8 in the third.
Coverage
Regarding the planning goals, 10 accessibility tools have a multi objective structure. 8 of the other tools are mainly aimed at deciding on the location of residences, activities or services – urban planning oriented. The remaining 4 are focused on managing, encouraging or reducing the use of a particular transport mode – transport planning oriented.
