This report noted several issues with current travel demand models that impede their ability to accurately assess transit access modes. As detailed in Appendix B and TCRP Web-Only Document 44: Literature Review for Providing Access to Public Transportation Stations, this research effort conducted a detailed review of published C H A P T E R 5 Travel Demand Considerations

However, realizing such a high percentage is largely dependent on factors outside transit agency control, as system-wide quality of bicycle facilities, topography, weather, and bicycle culture all play large roles in people's willingness to bike. Even so, research indicates that provision of bicycle facilities at transit stations, in particular high-quality bike parking, does have a significant impact on bicycle access.

Station Access Model A station access model was developed based on land use and ridership information assembled from public transport systems across the United States, including heavy rail and commuter systems serving strong downtown areas (New Jersey Transit, New York Metro-North, Washington, D.C., Boston, and San Francisco) as well as light rail systems in smaller cities (Denver and Portland)

was unavailable for incorporation into the modeling. The results of the modeling effort are consistent with the literature review findings: population density, employment density, and available parking are the most important factors determining station access decisions.

Pricing parking spaces provides an important means of recovering some of the initial development costs and/or ongoing operating costs of the parking. However, charging for parking may also reduce demand for parking and thus ridership.

Where a transit agency has produced specific elasticity values, these should be used instead.

The process requires knowledge of existing travel patterns and reasonable estimates of future population, employment, and land development. Estimates can be made either by using this report's station ridership model and access planning tool (or an agency-specific model)

The analysis may also be extended to also estimate mode split and parking demand.

Travel Demand Considerations 53 Exhibit 5-9 shows that the proposed station could have daily boardings of between approximately 3,000 and 3, 400. This ratio or interpolation method requires that the land uses at the proposed stations are similar to those at adjacent stations.
