Travel Behavior

Case studies examined how airport operators addressed bicycle access to their properties and the motivations and obstacles that they faced in light of new policies to integrate bicycles, along with transit and walking, into transportation planning, design, and construction and to increase the bicycle's role in the transportation system. Eight influential elements that emerged from the review of policy documents and research literature were used to guide interviews: governance structure, location, access roads, self-perceived environmental stewardship, spending restrictions on nonaviation...

The San Francisco–Oakland Bay Bridge, connecting San Francisco and the East Bay, is one of the most heavily traveled corridors in the nation. In an effort to address traffic congestion in this corridor, the Bay Area Congestion Pricing Task Force—a group of business, environment, public interest, and government organizations—has been examining the viability of variable tolls on the Bay Bridge. Tolls would be higher during peak commute hours when demand is highest and lower in off-peak hours when the bridge has excess capacity. This supply-and-demand-based concept is known as congestion...

Scholarship on citizen activism in a digital era is growing exponentially in sociology, political science, and communications/new media studies. Theorists observe changing dynamics and power shifts within a public virtual sphere. In contrast, planning scholarship is sparse on how citizens use technology outside of official channels to participate and mobilize. To explore this under-studied phenomenon, a new conceptual framework is developed by synthesizing literature across disciplines to examine digital networked activism in planning and focusing on conservative activists’ fierce...

This report provides background on efforts to date of the U.S. Department of Transportation’s (USDOT) Integrated Corridor Management (ICM) System Program for the Interstate 15 corridor in San Diego County, one of eight sites selected to participate in the USDOT ICM program. The program’s goal is to counteract the effects of increasing congestion area on freeways, arterials and the public transit network. The report focuses on Stage II of the ICM project. Stage II work was scheduled for completion in Fall 2009, and was to be followed by Stage III, which includes implementation. The report...
