Important Travel Definitions

• Routine: Travel involving stopping at activity locations (e.g., not purely exercise/recreation)

• Trip: A movement between a pair of activity locations, or stops (e.g., store to office).

• Stage: A movement made using a single mode of transportation. All trips have at least one stage.

• Tour (Trip-Chain): The set of all trips that a person makes from leaving home until returning home.

Example: Tour

3) Mode Choice Decision Process

El Cerrito

In-Depth Interviews

• 26 of the survey participants

• Spring and Summer 2010

• Conducted by phone

• 30 to 60 minutes

5) Habit(People who choose a particular mode

regularly are more likely to consider it as an option in the future)

2) Basic Safety & Security(People seek a mode that they perceive to provide a basic

level of safety from traffic collisions and security from crime )

3) Convenience & Cost (People seek a mode that will get them to an activity using an

acceptable amount of time, effort, and money)

4) Enjoyment(People seek a mode that provides personal (e.g., physical, mental, or emotional), social, or environmental benefits)

Pedestrian, Bicycle, Transit, or Automobile?

1) Awareness & Availability(People must be aware of the mode and have it available as

an option to travel to an activity)

Theory of Routine Mode Choice Decisions

Situational Tradeoffs













Socioeconomic Factors

(Explain differences in how people respond to each step)















Quotes: Awareness & Availability

• “He rides his bike because the cost of gas and he’s an environmental major…his attitude really did change when he became aware.” --Female, Age 52, San Carlos

• “Working people that are driving…don’t have the mind to think, ‘Am I doing things right?’ You are just surviving.” --Male, Age 30-39, Berkeley

• “So if one person starts cycling, and everyone starts seeing it, everyone will start cycling.” --Male, Age 40-49, Pleasanton

• “I am unemployed and can’t afford to buy a bicycle.” --Female, Age 20-29, San Francisco Market Street















Quotes: Basic Safety & Security

• “I can’t walk there because of the cars that are speeding on Bayshore…and it really bothers me because it’s the one little green open space that I could walk to…within 500 yards of my house, but I can’t get there because of the traffic.” --Female, Age 40-49, San Francisco Third St.

• “If there was less traffic…I probably would walk even more.” --Male, Age 30, San Francisco Fillmore Street

• “I’m not a skilled bicyclist…on the road, so I don’t really feel safe at all.” --Female, Age 30-39, Daly City

• “Right now I wouldn’t bicycle. I had a neighbor who had a terrible accident on a bicycle…” --Female, Age 52, South San Francisco

• “Bicycling itself…I would do it if I wasn’t right up next to cars.” --Female, Age 52, South San Francisco

Quotes: Basic Safety & Security

• “That’s how I got mugged, walking from my car to my house…I thought I might be walking more, but when I actually [moved] here, I realized that I couldn’t.” --Female, Age 40-49, San Francisco Third Street

• “When you are walking in this neighborhood, there’s nobody else walking. You look like a target here.” --Female, Age 40-49, San Francisco Third Street

• “We don’t live in a world that is as safe as it used to be…That’s why most parents don’t have their children biking around or walking out on the streets alone.” --Female, Age 40-49, Danville

• “There’s sometimes a fear of being stranded and not being able to get back, and you are at a distance from your home…I think a car gives you a feeling of security.” --Male, Age 60-69, Brentwood















3) Convenience & Cost

Accessibility of Activity Locations

Short distances to activities decrease and long distances to activities increase barriers to

walking and bicycling:

Availability and Price of Automobile Parking

Limited automobile parking increases and plentiful parking decreases barriers to driving:

• Planning time• Travel time• Physical effort• Packages• Bad weather

• Hills• Lack of lighting• Traffic risk• Sterile streets

• Planning time• Travel time

(searching for spot & walking from parking)

• Price (limited parking is often expensive)

Interview Quotes about Accessibility& Parking


"The next grocery store is about 4 to 5 miles away, and I wouldn't think about walking or bicycling."--Female, Age 40-49, Pleasanton

“Everything for us is like almost walking distance of where we go. I never drive."--Male, Age 30, SF Fillmore Street


"Living here in the suburbs...you get really used to parking not being an issue. Wherever you go, you can park."--Female, Age 60-69, South San Francisco


"I travel less. Because I know coming home, there won't be parking."--Female, Age 40-49, SF Third Street
















Quotes: Enjoyment

• “I have noticed that my stress level has gone down since I have walked and bussed more than I drive.” --Male, Age 30, Burlingame

• “It’s a beautiful block with beautiful trees, and I love walking down that street. I wish every street had trees.” --Female, Age 40-49, San Francisco Third Street

• People bicycle “for exercise, for convenience, and for fun.” --Female, Age 20-29, San Francisco Market Street

• “[Bicycling is] a good way to get some exercise, and it’s less pollution…part of it may be that it’s kind of trendy.” --Male, Age 30, San Francisco Fillmore Street















Quotes: Habit

• “I think that getting into the habit of [walking and bicycling] early makes one I think more likely to continue doing them into their later years.” --Male, Age 55, San Francisco Third Street

• “I’m used to using a car. It’s easy. I can get in; I can park in my driveway at night. I get in, I go.” --Male, Age 55, San Francisco Third Street

• “The younger ones—a lot of them drive their cars to high school or to college…That’s probably all they know, really.” --Male, Age 30, Burlingame

• “In the United States actually, we tend to think about the car being the first and the only mode of transportation, and we need to get out of that mindset.” --Female, Age 40-49, Pleasanton

1) Awareness & Availability(Institute individualized marketing programs, bicycle give-away

programs, community-wide education campaigns, Bike to Work Day, Walk to School Week, and other encouragement programs)

5) Habit(Offer information to people who move & change job locations; Explore roadway and

parking pricing strategies)

2) Basic Safety & Security(Construct sidewalks and bicycle paths; Improve pedestrian

crossings; Designate roadway space for bicycles; Design roadways for slower automobile speeds; Educate pedestrians, bicyclists, and drivers on safe behaviors; Enforce traffic laws; Improve roadway

lighting; Provide secure bicycle parking )

3) Convenience & Cost(Allow higher population and employment densities and a finer mix of land uses; Reduce building setbacks; Reduce automobile lanes;

Reduce off-street parking and provide market-rate on-street parking)

4) Enjoyment(Plant street trees and landscaping; Zone for ground-level stores

adjacent to sidewalks; Design public streets for slow-speed activities; Promote environmental & social benefits of walking and bicycling)

Theory of Routine Mode Choice DecisionsSocioeconomic Factors



Important Considerations

• Small bicycle sample size

• Fair weather conditions only

• Tour purpose not controlled in secondary model (N=959)

• Exploratory-level statistical significance

• Cross-sectional data

• Mode choice theory based on San Francisco Bay Area subjects and applies to routine travel

Previous discrete choice modeling studies with pedestrian & bicycle modes

• Purvis (1997)

• Bowman & Ben-Akiva (2000)

• Jonnalagadda et al. (2001)

• Berrigan & Troiano (2002)

• Cervero & Duncan (2003)

• Walton & Sunseri (2007)

• Ryley (2008)

• Kim & Ulfarsson (2008)

• Handy et al. (2010)

Value of Time (N=388)

• Analysis of tours that had all stops within shopping district (½-mile of store)

• Included travel time and out-of-pocket cost in model instead of tour distance, metered parking, zero vehicles & bus pass

• Value of time

– Automobile tours = $14.41/hour

– Public transit tours = $9.23/hour

– BATS 1990 shopping trips in 2009 dollars = $10.90/hour

Bicycle Facility Tradeoffs (N=959)

• Analysis of all respondent tours (not just to and from shopping district)

• Value of bicycle facilities

– Each additional mile of bicycle facilities in the shopping district was associated with respondents bicycling 1.6 miles further

– Each additional bicycle parking space at the survey store was associated with respondents bicycling 0.5 miles further

Automobile Facility Tradeoffs (N=286)

• Analysis of walk vs. drive within shopping districts

• Value of automobile facilities

– Shopping districts with metered parking were associated with respondents walking 2.5 minutes longer

– 10 fewer commercial driveway crossings along the main shopping district roadway were associated with respondents walking 1.0 minutes longer
