Accessibility, or the ease of travel between two locations, is an appropriate measure for walking and cycling because of the heavily constrained nature of walking and cycling trips. Much attention has been focused in recent years on the connection between the built environment and the transportation system. This relationship is especially relevant for walking and cycling as literature has shown that spatial layout and infrastructure design are significant factors in the ability to make walking and cycling trips. Unfortunately, a quality method does not exist to quantify walking and cycling accessibility. Most accessibility measures have concentrated on the macro level while walking and cycling by nature occurs mainly at the micro level. The few attempts at measure micro-scale accessibility have serious drawbacks. This thesis synthesized recent research on the connection between the built environment and transportation to develop a new accessibility measure that can identify areas conducive to walking and biking. This measure, the Pedestrian and Cycling Accessibility Measure (PCAM), is based on the concept of the .3Ds,. or density, diversity, and design. Corresponding to this research, the PCAM first considers the proximity of residential areas to specific destinations within walking and biking ranges (density) and the mix of destinations immediately surrounding these destinations (diversity). This part of the PCAM demonstrates the potential for walking and biking trips in a given area. Once this analysis is complete, the physical design of the pedestrian and cycling infrastructure (or lack thereof) are examined to determine if the necessary infrastructure is in place to support the potential walking and biking travel (design).
