It’s Friday, the end of the work week, and all everyone wants to do is get home as quickly as possible. For the transit rider, it is time to enter the arena of unknown bus reliability. Will my bus come? Will it be on time? How bad will traffic be? We have all mentally asked these questions, but some have to ask them more than others.
Today we will look at the 5 buses that have the worst afternoon reliability in the Metro system and consider what can be done to improve them. These routes are generally low ridership and wouldn’t merit much capital investment, so we’ll focus on quick fixes where appropriate. Conveniently, each one of our tardy routes is from a different portion of the county. (On time data is from the King County Metro 2018 System Evaluation. )
Nine years ago Martin looked at the general problem of I-5 buses terminating at Rainier Beach. However, removing buses from the Downtown Seattle Transit Tunnel provides an opportunity to review if there are cost savings or efficiency improvements by truncating routes formerly in the tunnel and forcing a transfer to Link.
Truncating is a balancing act: Riders can often save time by transferring to a congestion-free mode like light rail, and service hours saved can be used to provide more frequent service on the shortened bus line. However, the benefits can be diminished if the transfer is infrequent or inconvenient. Let’s look at King County Metro Route 150 as an example.
The 150 runs from Kent Station to Seattle, providing service from roughly 5 a.m. to midnight with pickups every 15 minutes during the day Monday through Saturday. On weekdays in the fall of 2017, it carried about 6,200 passengers, comparable to RapidRide B. The 150 also serves as the direct connection to Seattle from Kent since there is no ST Express bus. How would truncating the 150 at Rainier Beach Link station affect quality of service for north- and southbound riders?
