Chapter Two: A Decision-Making Framework Focused On System Performance And Multimodal Integration<br />
peak hours. 55 This occurs despite high occupancy vehicle lanes performing substantially<br />
below travel speed standard, with travel times well above target 56 and more frequent<br />
traffic breakdowns that produce far longer delays. 57 The high-occupancy vehicle travel time<br />
advantage, 20 minutes in 2013, has shrunk to 15 minutes. 58 At the same time, more crowded<br />
buses indicate greater demand for transit and a greater number of people standing for 65+<br />
minute trips. 59 Transit reliability is also suffering, with more than 25 percent of bus trips<br />
arriving late. 60 Park and rides that serve as a key access point for transit on the corridor are<br />
chronically overcrowded. 61<br />
There are two primary ways to address this mobility challenge: increase the level<br />
of transit service provided on the corridor and improve transit flow. Transit agencies,<br />
local road agencies and the state have created a rapid response effort designed to boost<br />
transit’s contribution to I-5 performance. This effort focuses on increasing overall corridor<br />
performance through increased transit ridership. Examples:<br />

Since 2013, Community Transit and Sound Transit have added trips, buses and service to<br />
accommodate longer and less predictable travel times, and both agencies will be adding<br />
additional time into their schedules to reflect the new reality. In fall 2015, Community<br />
Transit and Sound Transit will be purchasing higher capacity vehicles (for example,<br />
double decker buses) to help reduce overcrowding.<br />

City of Seattle, Community Transit, King County Metro, Sound Transit, PSRC and<br />
WSDOT are collaborating on near-term achievable operational strategies and road<br />
modifications to improve transit speed and reliability between Everett and Seattle. A<br />
work team comprised of experts from Community Transit, WSDOT, First Transit and<br />
Spokane Transit developed a list of actions at an intensive workshop on March 10, 2015.<br />
Agencies are working to assess and implement these actions. For example, agencies<br />
are preparing to test the use of freeway shoulders as transit bypass lanes during heavy<br />
traffic congestion. A pilot project to test this concept on I-5 in south Snohomish County is<br />
in development for 2016.<br />
Providing a more reliable path for both in-service and out-of-service buses not only makes<br />
transit more attractive to commuters in the I-5 corridor; it also amplifies the effectiveness of<br />
transit investments in additional equipment and service by reducing the amount of money<br />
spent on buses sitting unproductively in traffic. These investments support the overall<br />
performance of the region’s transportation system. While the rapid response efforts proceed,<br />
regional discussions continue about longer-term solutions for I-5 performance and the<br />
impacts of increased demand.<br />
