Many agencies <br />lose 1 % or more per year in average operating speed, due to a combination of rising patronage <br />(which increases boarding times) and increased traffic congestion. <br /> <br />Traditionally, major transit agencies have set aside a portion of their expansion resources for <br />'headway maintenance,' which means adding buses to a line so that R has more time to complete <br />its cycle. This may be lhe only solution to a running time problem in the short term, but it does <br />nothing to arrest the downward slide in operating speeds. Instead, the transR agency simply pays <br />more drivers to endure ever-increasing delays, and tolerates the gradual deterioration in the speed <br />of the service. <br /> <br />When talking about transit speed, we are referring to traveltime. The buses do not have to travel <br />at faster speeds. The system must eliminate as much delay as possibility. <br /> <br />Transit operating speed is a crucial consideration for two reasons. First, time is money; the longer <br />R takes to complete the cycle of a line, the more it will cost to operate a given frequency. Second, <br />the discretionary transit rider is very sensitive to speed. Because transR must stop to pick up <br />passengers, it will usually be slower than cars driving on the same street. If R is too much slower, R <br />will lose passengers to the automobile. <br /> <br />For these reasons, every major transit agency needs a comprehensive speed-protection strategy. <br />The goal of such a strategy should be to set and maintain an average service speed policy on <br />every line even as congestion, ridership, and other factors increase. The policy speed, of course, <br />would vary with the line, but the slowest services - urban locals - are also the most crowded, so <br />even the loss of 1 mph in speed can have cost and ridership impacts. Ultimately, the policy speed <br />should be included in the street classification system of the local jurisdiction, so that a deficiency in <br />transR speed becomes visible as a problem just as deteriorations in traffic Level of Service do. <br /> <br />e <br /> <br />Eventually, protecting the policy speed requires joint action between the transR agency and the <br />local jurisdiction that manages the roadway in question. In some cases, Metro TransR can take the <br />lead in making changes that improve speed. In other cases, the local jurisdiction that controls the <br />roadway would take the lead. Virtually all of these measures, however, require cooperation <br />between Metro Transit and the local jurisdiction in question. The following brief descriptions <br />identify the typical lead agency in each case. <br /> <br />Stop Spacing <br /> <br />On many major Metro Transit lines, stops are extremely close together. Often, they are located at <br />every intersection, which in the core cities can mean every 300 feet or less. An ideal stop spacing <br />is close enough that everyone in the surrounding area can walk to a bus stop, but no closer. Two <br />blocks, typically about 600 feet, is a common spacing standard in the industry, and even this <br />spacing, if applied uniformly at Metro Transit, would speed up service noticeably. However, the <br />maximum tolerable spacing for local lines is usually in the range of 800-1000 feet, or about three <br />city blocks. <br /> <br />e <br /> <br />Nelson \Nygaard Consulting <br /> <br />7-2 <br /> <br />November 2, 1999 <br />
