Survey Results

The survey was distributed online and via paper copies in five languages (English, Spanish, Chinese, Vietnamese, and Tagalog) from June 1st to mid-August, 2019. We received 2,355 responses. The short survey had questions about travel along US-101 today, the mobility barriers people experience, and how travel might change in the future.

Respondents are receptive to strategies that encourage higher vehicle occupancy, like carpooling, and lowest income travelers are the most likely to directly benefit.

Carpooling is a common activity on US-101, even without designated high-occupancy vehicle (HOV) or express lanes on 101 north of Redwood City. Among respondents, households with lower incomes carpool at higher rates.

When asked about tradeoffs, there is a slight preference to carpool to save time or money on parking, as opposed driving alone, but this varies significantly by income group. Respondents from households earning under $50,000 are the most likely to prefer to carpool to achieve these savings.

Respondents indicated a slight preference for traditional carpool arrangements over dynamic ride-matching services, such as Scoop and Waze Carpool that allow you to find carpool partners on the fly. Increased awareness and adoption of these services may be required to leverage their potential in incentive programs.

Survey respondents use transit and are interested in investments in transit frequency, reliability, and free transit pass programs.

Multiple transit agencies and employee shuttles serve the communities along US-101 in Santa Clara, San Mateo, and San Francisco counties. 60% of all respondents take Caltrain at least occasionally, which runs parallel to US-101 for nearly its entire route.

When asked to prioritize investments, respondents ranked transit investments the highest.

Overall, survey respondents would choose predictability on transit over the unpredictability of driving. The trend is strongest for higher income households.

Respondents make travel decisions based on travel time and reliability and are most motivated to rethink travel decisions when offered tangible incentives.

When asked to think differently about their travel on the corridor, respondents are most motivated by certain and tangible rewards, such as financial benefits and transit passes.

Further, natural incentives emerge by examining the tradeoffs people would make between different travel scenarios. Respondents prefer:

  • To ride transit if it is faster and more reliable than driving (speed and reliability incentive)

  • To carpool if it is faster than driving alone (speed incentive)

  • To carpool to save money on parking when parking is priced (cost savings incentive)

  • To adjust their schedule to avoid paying a toll (cost savings incentive)

Respondents experience stress and unpredictability traveling on US-101, and communities near the freeway experience additional stress from pollution and spillover traffic.

Respondents are most concerned about congestion and reliability on US-101 and the stress it creates in their lives.

Looking at the same responses by proximity to US-101, concerns about air pollution, spillover traffic, and street safety become greater for people living closer to US-101.

Daily travel crosses city and county boundaries, pointing to a need for regional coordination to address mobility challenges.

On average, respondents’ home-to-work travel distance is about 15 miles “as the crow flies.” When mapped to the street network, travel distances would be much greater. Slightly more than a third report travelling over 20 miles, and over half travel 6-20 miles for their most common trip on US-101. This affirms the need for regional coordination to address regional travel patterns.

Respondents’ most common home and work zip code pairs illustrate a high reliance on the US-101 corridor

Who We Heard From

The survey was distributed online and paper* copies were distributed in five languages (English, Spanish, Chinese, Vietnamese, and Tagalog) from: June 1st to mid-August, 2019. We received 2,355 surveys.

The split of responses by County is roughly proportional to the split of overall population across those counties, with the exception of San Francisco, which was underrepresented.

*Paper surveys were handed out at events and through outreach networks that included affordable housing sites with free transit passes, particularly in Santa Clara County.

Low-income households are also underrepresented in the survey. Households making $50,000 a year or less make up the smallest portion of respondents (12%), as compared to 26% of the population across the three counties.

18% of the responses indicate that they speak a language other than English at home, but only 9% took the survey in a non-English language. This is compared to 20% of the population overall reporting non-English languages spoken at home.

Another aspect of understanding travel on US-101 is asking about the barriers to access people experience along the corridor, such as vehicle access, restrictive schedules, and bank, credit card, and phone access. Across all barriers, income has a strong correlation. Lower income households report higher rates of barriers and higher income households report better access.
