Activity Surface Example As indicated in a previous section, where sufficient demographic and land-use data are available in GIS format, an activity surface can be created to depict the land-use and travel patterns. Figures 5-16 through 5-18 and Table 5-3 show an example of how this activity surface can be tied to suburban transit service planning.

Establishing Performance Measurement Programs Evaluating suburban services is an important component of the successful implementation of suburban services. Not only is it important to ensure that the form of transit is appropriate for the market, but equally important is ensuring that expectations in a community are commensurate with performance.No other form of public transit engenders more local characteristics than suburban transit.
