King County Metro will increase reliability and build resiliency with its fall update to transit schedules. The agency currently is delivering 95% of more than 11,200 daily bus trips while facing challenges with canceled trips. The changes beginning in September will ensure riders can have confidence knowing that Metro will be there no matter where they need to go.

To ensure transit services are in sync with fleet availability and its workforce, Metro will focus upcoming revisions on 20 low-ridership routes, and 92% of boardings will not be directly impacted. These changes will help prevent last-minute cancellations and improve reliability for riders. Metro will help connect riders with other transit options for nearly all the impacted routes.

“We designed the September service change guided by our customers,” said King County Metro General Manager Michelle Allison. “These adjustments mean riders will know their trip will be there. This approach also better positions Metro to grow our transit network in future years.”

The vast majority of Metro’s routes – 124 of 156 routes – will be preserved and see no changes. Metro sought to protect several categories of service, including routes that have high ridership demand and where there were few alternate transit options. Routes protected from significant changes also serve a higher percentage of riders who have lower incomes or identify as Black, Indigenous and other communities of color. By adjusting schedules and suspending routes, the upcoming service change will deliver roughly the same number of transit trips currently operating on the road, without the day-to-day variability that has inconvenienced riders during the past several months.

“Reducing service to make our transit schedule more accurate is neither a rest nor a retreat,” said Allison. “We’re engaged in full-scale business transformation across recruiting, training, retention, fleet maintenance and agency-wide innovation. Metro is working harder than ever to deliver your service every day, to strengthen and improve our agency, and to grow transit region-wide.”

September was the next opportunity to make updates across customer information, service planning and staffing. By sharing this information months ahead of the change and highlighting alternate transit options, riders on affected routes can be better prepared to adjust their travel if needed in the fall.

Suspended routes have alternatives available

These 20 routes will be fully suspended beginning Sept. 2. Each of these routes has alternatives, and most are available either at the same bus stops or nearby. Routes 15, 16, 18, 29, 55, 64, 114, 121, 167, 190, 214, 216, 217, 232, 237, 268, 301, 304, 320 and 342.

Reduced trips

Twelve bus routes will be reduced to operate less frequently: Routes 7, 10, 20, 28, 36, 73, 79, 225, 230, 231, 255, 345. Some high-ridership routes such as 7 and 36 will continue to have very frequent service, with wait times of just a few more minutes. Some low-ridership routes will shift to service every 30 to 60 minutes during some time periods.

By the numbers

Operators: As of April, Metro has 2,484 transit operators, including 571 part-time bus drivers and 1,913 full-time bus drivers. An estimated 172 additional full-time equivalent, or a combination of 113 full-time operators and 99 part-time operators, are needed for current service levels. Service levels will be aligned with estimated available workforce in September.

Mechanics: As of April, Metro has 231 full-time bus mechanics. An estimated 252 are needed for current service levels. An estimated 12 additional mechanics are needed for September 2023 service levels.

Canceled trips: Metro has 11,200 scheduled weekday trips. But fleet availability due in large part to supply chain challenges and operator availability has reduced our trip delivery to 95%.

System service levels: Of Metro’s 156 bus routes, 124 routes will have no changes. These unaffected routes carry an estimated 1.21 million of Metro’s 1.38 million weekly boardings. The total system reduction in September is an estimated 150,000 service hours, or 3.8 percent of Metro’s 4 million annual service hours. Until September Metro will continue to operate as much of its scheduled service as it can, which is currently about 95% of service.
