The NE 85th Street and Redmond Way Corridor Study examined improvements to increase transit speed and reliability through the arterial corridor. This corridor, also designated as State Route 908, is a five-lane arterial with an interchange with Interstate 405 at the west end of the corridor. Several improvements were considered including adding dedicated bus lanes along the length of the corridor as well as completing individual intersection projects. The improvements were evaluated by conventional intersection measures of performance, such as average delay and queue length. Benefit-to-cost ratios were used to determine the return on investment by the transit agency of each enhancement alternative. The bus travel time benefits realized from corridor-wide and combinations of relatively small intersection improvements were comparable and significant. Further, the benefit-to-cost ratio for the intersection improvements was comparable and outweighed those of the corridor-wide improvements. The study showed that in this suburban setting, getting buses moving means getting all of the traffic moving.
