US-101 MOBILITY ACTION PLAN
PROBLEMS FACING
US-101 TODAY
Problem: Travel time on US-101
is unpredictable
Travelers driving on US-101 have to add 25-55% more time to arrive at their destination predictably. Buffer Time Index (BTI) is a measure of the amount of time above the average travel time that a driver needs to assume for an on-time arrival at the desired destination.
Problem: Worsening congestion limits access for all
Commuters experience nearly twice as much delay today as in 1998 – US-101 is no exception.
Problem: US-101 is not moving as many people as it could be
At the peak hour 78% - 87% of all vehicles on US-101 are carrying only one person, with only 22% - 13% of vehicles carrying two or more people.
Problem 4: US-101 causes health and mobility problems for adjacent communities
Asthma rates are higher adjacent to US-101 and especially at interchanges. Traffic volumes are highest in communities with highway access points.
Problem 5: Congestion, unpredictability, and limited transit options present mobility challenges for all, but some groups are more vulnerable.
Low-income populations must choose between increasingly longer transit commutes and spending a larger share of their income on a car.
GOALS OF THE US-101 MOBILITY ACTION PLAN
The ideal US-101 corridor serves the region equitably in service to three goals:
Offer reliable travel times for all people, regardless of how they travel
Prioritize high-capacity mobility options for all
Foster healthy and sustainable communities along its right-of-way
GOAL 1: OFFER RELIABLE TRAVEL TIMES FOR TRAVELERS ON US-101
Ensuring reliable travel times helps corridor workers and residents arrive on time to jobs, services, and other destinations. When a corridor is unreliable, travelers may have to add “buffer” time to their trip to avoid being late. This has the greatest impact on low-wage employees working hourly or shift jobs, which typically require stricter schedules and start times than higher-paid salary positions.

GOAL 2: PRIORITIZE HIGH-CAPACITY MOBILITY OPTIONS
Vehicle capacity is the number of people that can fit inside a vehicle. Higher-capacity vehicles, such as buses or trains, can move many more people than single-occupancy cars while using a similar amount of space on the road. Prioritizing higher-capacity mobility options and protecting those vehicles from congestion helps use the corridor more efficiently. Improving the occupancy of personal vehicles by encouraging carpools also helps increase the capacity of the corridor to move more people.
