California's Paradigm Shift From Los To Vmt As A Transportation Impact Metric: Policies, Politics, And Possibilities, Robert Liberty, Lynn Peterson
California's Paradigm Shift From Los To Vmt As A Transportation Impact Metric: Policies, Politics, And Possibilities, Robert Liberty, Lynn Peterson
PSU Transportation Seminars
As part of California's effort to reduce greenhouse gas emissions, the state has passed a law leading to a radical shift in how it analyzes the traffic impacts of new land use developments and transportation projects. SB 743's goal is to "more appropriately balance the needs of congestion management with statewide goals related to infill development, promotion of public health through active transportation, and reduction of greenhouse gas emissions."
The new measure of transportation impacts will be based on vehicle miles traveled (VMT) instead of level of service (LOS). This ground shift has broad implications for lead agencies, planners, MPOs, …
Dynamic Assignment Models And Their Application In The Portland Metro Region, Peter G. Bosa
Dynamic Assignment Models And Their Application In The Portland Metro Region, Peter G. Bosa
PSU Transportation Seminars
Metro's Research and Modeling Services Program is responsible for the development, maintenance, and application of travel demand models for application in long-range planning efforts in the Portland metropolitan region.
Representation of traffic—both vehicular and transit—plays an integral role in the travel demand modeling process. Complex software is required to assign vehicles and transit users to transportation networks to determine viable options available to travelers, costs associated with those options, and sets of routes by which travelers might navigate their trips.
Metro's current static assignment model has traditionally sufficed for use with Metro's four-step travel demand model. However, static assignments have …

Exploring The Positive Utility Of Travel And Mode Choice, Patrick Allen Singleton
PSU Transportation Seminars
Why do people travel? We traditionally assume traveling is a means to an end, travel demand is derived (from the demand for activities), and travel time is to be minimized. Recently, scholars have questioned these axioms, noting that some people may like to travel, use travel time productively, enjoy the experience of traveling, or travel for non-utilitarian reasons. The idea that travel can provide benefits and may be motivated by factors beyond reaching activity destinations is known as “the positive utility of travel” or PUT.
This study presents a conceptual and empirical look at the positive utility of travel and …
