TCRP Report 121: Toolkit for Integrating Non-dedicated Vehicles in Paratransit Service is a toolkit that can be used by transportation managers to determine the appropriate split between dedicated and non-dedicated paratransit services to increase cost-effectiveness and meet peak demand needs. This report includes a Non-dedicated Vehicle Optimization (NDV) Model and User Manual. The NDV Model is spreadsheet-based and may be used by paratransit system managers and planners to assist with making decisions regarding appropriate service ratios for specific conditions and environments. In addition to the toolkit, a Case Study Report and an Interim Report (which includes an analysis of factors that influence the mix of dedicated and nondedicated paratransit service) are available for download from the project’s website.

Status: The revised final report has been published as TCRP Report 121.
