Travel Demand

Level of Service, the Wrong Performance Measure
The use of level of service (LOS) to gauge the success of roadway networks has shaped and influenced cities in many negative ways.

Peak Car Revisited
U.S. vehicle travel increased 3.2% (8.6 billion vehicle miles) in total and 2.0% per capita between Junes 2015 and 2016. That is a new peak in total VMT, but a 2.75% reduction in per capita VMT. Will these growth rates continue into the future?

Millennials Are in Motion, But Not Necessarily by Car
A new report from the U.S. Public Interest Research Group and Frontier Group shows mounting evidence that the Millennial generation’s dramatic shift away from driving is more than temporary. Planning must change to accommodate these demands.

New Study Predicts Vehicle Travel Saturation Levels

A Critical Evaluation of the USDOT Conditions and Performance Report
The “Status of the Nation’s Highways, Bridges, and Transit: Conditions and Performance, Report To Congress” is intended to provide a comprehensive and objective evaluation of our transportation system. Let’s evaluate this evaluation.

USDOT Continues to Overestimate Future Vehicle Travel - When Will They Learn?
The USDOT's "Conditions & Performance Report" predicts that VMT will grow between 1.36% and 1.85%, although current demographic and economic trends have resulted in flat or negative growth in recent years. Why won't they learn?

Car-Sharing Already Impacting Auto Sales
Demographic and economic trends, and improving transport options, including more carsharing services, are contributing to a long-term decline in automobile ownership and use.
Changing Travel Demands: Implications for Planning
The graph below shows the most recent USDOT vehicle-travel data covering the last 25 years. Although vehicle-miles of travel (VMT) grew steadily during most of the Twentieth Century, in recent years the growth rate stopped and even declined a little. It is now about 10% below where it would have been had past trends continued.
Travel Demands Are A-Changing: So Should Our Spending
Politicians and planners be warned: you will now be judged according to your ability to improve walking, cycling and public transit services.
