In the context of implementation of SB 743 (Steinberg, 2013), staff at the California Department of Transportation (Caltrans) have been developing guidance documents on how to calculate induced travel, working with their counterparts at the California Air Resources Board (CARB) and the Governor’s Office of Planning and Research (OPR). OPR’s technical advisory discusses two methods for estimating induced travel: an approach based on the application of travel models and an approach using elasticities drawn from the peer-reviewed literature (such as the National Center for Sustainable...

This report explores how working families in seven major metropolitan regions (Atlanta, Chicago, Dallas–Ft. Worth, Los Angeles, New York City, the San Francisco Bay Area, and Baltimore–Washington) tradeoff housing and commuting costs, and how their tradeoffs differ from those of wealthier families. It is organized into five sections. Beyond this brief introduction, the report consists of five parts. Section 2 introduces the PUMS (Public Use Microdata Sample) database, upon which this analysis is based, and presents the procedures used to identify the seven case study metropolitan regions....

This synthesis provides a summary and comparative analysis of actions states across the United States are taking inresponse to automated vehicles (AVs). The research focuses on state-level stakeholder forums (e.g., task forces, committees) and state-level strategic actions (e.g., studies, initiatives, programs) initiated by a state legislature, agovernor, or a state agency. The analysis found that AV stakeholder forums and strategic actions address a diverse set offocus areas, but they pay minimal attention to the implications of AVs on the environment, public health, social equity, land...

Dynamic toll pricing based on demand can increase transportation revenue while also incentivizing travelers to avoid peak traffic periods. However, given the unpredictable nature of traffic, travelers lack the information necessary to accurately predict congestion, so dynamic pricing has minimal effect on demand. Dynamic toll pricing also poses equity concerns for those who lack other travel options. This research explores a potential remedy to these concerns by using a simple “futures market” pricing mechanism in which travelers can lock in a toll price for expected trips by prepaying for...
