Guidebook on Methods to Estimate Non-Motorized Travel: Overview of Methods
This two-volume guidebook describes and compares the various methods and tools that can be used to forecast non-motorized travel demand or that otherwise support the prioritization and analyses of bicycle and pedestrian facilities. The guidebook is intended to be used by bicycle and pedestrian planners, technical staff, researchers, advocates, and others who may wish to estimate bicycle and pedestrian travel demand or to prioritize bicycle and pedestrian projects.
This second volume, Supporting Documentation, gives details on each method, including purpose, structure, input / data needs, assumptions, and real-world applications. This volume contains an extensive annotated bibliography of references on demand forecasting methods, supporting tools and techniques, and factors influencing the choice to walk or bicycle, as well as potential contacts in this field. The other volume, Overview of Methods, provides an overview of each of nineteen methods appropriate for forecasting and/or understanding pedestrian and bicycle travel demand.

This guidebook provides a means for practitioners to better understand and estimate bicycle and pedestrian travel and to address transportation
planning needs. The guidebook describes and compares the various methods that can be used to forecast non-motorized travel demand or that otherwise
support the prioritization and analyses of non-motorized projects. These methods are categorized according to four major purposes: (1) demand
estimation; (2) relative demand potential; (3) supply quality analysis; and (4) supporting tools and techniques. Discrete choice models, regional
travel models, sketch plan methods, facility demand potential, bicycle compatibility measures, and geographic information systems are among
the methods and tools described.
Overview of Methods provides a concise overview for each available method, including some typical applications, pros and cons, and a quick
reference guide on ease of use, data requirements, sensitivity to design factors, and whether widely used. In addition, it discusses general
issues for consideration in forecasting non-motorized travel demand, such as the dimensions of travel behavior and factors influencing bicycling
and walking, and identifies future needs in this area.
Supporting Documentation provides substantially more detail on the methods including purpose, structure, input/data needs, assumptions,
and real-world applications. It also contains an extensive annotated bibliography of references on demand forecasting methods, supporting
tools and techniques, and factors influencing the choice to walk or bicycle, as well as potential contacts in this field.
