Travel training provides a promising approach for moving persons from paratransit to fixed-route transportation services. This study identifies current funding trends and discusses the volume and diversity of services within the travel training instruction field. Measuring the emergence of this field focused on four properties of systems: intention, boundary, resources, and exchange. We used these properties to facilitate sharing of information and learning among the participating organizations. Initial findings indicated that older, established programs tended to be larger and moved more persons to fixed routes, while programs that employed their own staff rather than contracting out staff produced more outputs per staff person. We conclude that the diversity of the field’s innovators have strengthened the problem-solving capacity. Based on the findings, a preliminary research and evaluation agenda is proposed.
