Simple lane change speeds up TriMet Line 15 buses


Delays declined 11 percent or more following PBOT’s creation of shared bus/bicycle lanes in Southeast Portland

TriMet operators and riders are praising recent, simple improvements that help buses keep moving, even during high traffic rush hours. We’re working with the Portland Bureau of Transportation (PBOT) and the Oregon Department of Transportation (ODOT) to speed up transit in areas where our buses often get slowed down. The addition of bus/bike lanes on the approach to 82nd Avenue in Southeast Portland has reduced delays on Line 15-Belmont/NW 23rd 11 percent or more.

A bus operator’s view

TriMet bus operator Allen Tanner has been driving Line 15 off and on, for about three years. He enjoys the route, with its view from Mount Tabor, but he found some of the driving conditions to be frustrating. He estimates congestion on Southeast Stark and Washington leading up to 82nd Avenue had slowed his bus by five minutes or more during the morning commute.

“It’s not very much fun because you don’t feel that you’re making the progress you should be making as far as schedule and getting the people where they want to go,” said Tanner.

The solution

Last May, PBOT converted the right hand, westbound lane of Southeast Stark Street from about 85th Avenue to Southeast 82nd Avenue. Buses and bikes go straight through the intersection, but cars must turn right. Known as a pro-time bus lane, parking is allowed in sections of the lane, just not between 6 a.m. and 9 a.m. The temporary adjustment reduced delays by 8 percent during the morning commute and 3.7 percent all day.

In August, PBOT made a similar change on Southeast Washington Street, where Line 15 travels eastbound toward 82nd Avenue. From about  80th to  83rd Avenue, autos must turn right at intersections, but buses and bikes can go straight. Delays during the morning commute dropped by more than 11 percent, and fell 3.4 percent all day.

“It’s wonderful,” said Tanner. “When it first came in, it made a big difference right away, and I was grateful for it. I hope they put more in, throughout the city.”

Partnerships bring results

TriMet thanks our partner agencies for helping us speed up transit trips across the region. Since our buses use roads that are owned and maintained by cities, counties or the state, we need their help to make improvements. Since September 2017, 10 small and relatively inexpensive projects have been completed to speed up TriMet buses. Combined, they improved reliability and performance on 14 bus lines, reducing traffic-related delays by as much as 61 percent.

“PBOT is working hard with TriMet to make buses quicker and more reliable for people taking transit. Together, we are expediting transit projects in 2019 at three key Central City bottlenecks approaching the Burnside, Hawthorne, and Steel Bridges to get buses around traffic congestion. This will benefit 14 bus lines, and all the people on them, that cross the city and beyond,” said PBOT’s Transit Coordinator, April Bertelsen. “We are also developing more spot improvements, like this one on SE Stark and Washington approaching 82nd Ave, throughout the city where buses are delayed. Improving transit and helping bus riders move more efficiently through the city is very important to us.”
