In a town with little room to accommodate more automobiles a multi-modal approach to moving people might serve us better. For every person walking biking or using public transit (Municipal Bus, Trolleys, OCTA) we remove one person driving a car and free a parking space. But how do we know if a multi-modal system will serve us well? Do we know how many people are already using each mode? Could more people participate in each mode?
Let's take an assessment, what-if we could measure all the travel trips people make for work, pleasure, commuting, or errands nation-wide? Fortunately the National Household Travel Survey has done just that. This post shows study results by The Victoria Transport Policy Institute for 375,000 reported trips in locations across the nation.*
|POV = cars, vans, Suv's, motorcycles|
|POV= cars, vans, Suv's, motorcycles|
This chart shows the portion of trips made as a percentage of the total number of trips in the study, for each distance category, for each mode-share. This chart shows 41% of all the trips nation-wide are under 3 miles long. Trips 2.1-3 miles long are not served by walking, biking or transit services. Trips greater than 2.1 miles are the exclusive domain of the POV.
How do we spend our time when traveling, how far do we go and which mode-share is used most? This chart shows how we portion our trips, time traveled, and distance traveled for each mode-share. Among the modes we highly favor taking most trips with a POV.
These charts show nation-wide the automobile is king while other transportation modes are totally underutilized. Balancing the mode-share with walking biking and public transit nation-wide would reduce automobile congestion. Anyone stuck in Laguna traffic would reasonably conclude a balanced mode-share would serve Laguna as well.

Walking data includes walking from the parked automobile to the destination.
