161 This appendix is intended to provide transportation engineers and planners a better understanding of transit operations, describe how transit-supportive roadway strategies can help provide better transit operations, and explain why improving operations is an important goal of transit agencies. The first section contrasts the service-oriented nature of transit operations to the facilityoriented nature of roadways and discusses how operating costs have much greater importance for transit service than for roadways.

162 A Guidebook on Transit-Supportive Roadway Strategies B.2 Basic Route Scheduling Concepts Cycle Time Concepts Assume for the sake of example that a transit agency operates a route that is 6 miles long and that generates sufficient ridership to require service every 10 min (i.e., a bus headway of 10 min, corresponding to a frequency of 6 buses departing a stop per hour)

164 A Guidebook on Transit-Supportive Roadway Strategies B.3 Transit Performance Agency Stakeholders There are a variety of stakeholders with vested interests in transit operations and performance. The community at large is interested in, among other things, transit's role in providing transportation choices to members of the community, the transit agency's role as a creator and supporter of jobs, transit's role in reducing the environmental impact of the overall transportation network, and how service is distributed throughout the transit service area.

166 A Guidebook on Transit-Supportive Roadway Strategies • Required bus stop length to serve a given number of buses at a specified level of reliability, and • Impacts of changes in bus speeds on the quality of service perceived by passengers. The TCQSM's speed-estimation methods can be characterized as "planning level" or suitable for developing a small set of alternatives to evaluate further.
