Reducing Risk In Public-Private Partnership Contracts: Two Examples From Highway Tolling Projects, Martin Mayer, Juita-Elena Wie Yusuf, Lenahan L. O'Connell

School of Public Service Faculty Publications

In an effort to address financial constraints and environmental concerns states have increasingly turned to a combination of un-tolled (HOV) and tolled (HOT) lanes. Public-private partnerships (3Ps) are a popular mechanism for this more sustainable approach to highway infrastructure that couples environmental sustainability (efficient utilization of existing lanes, less congestion) with financial sustainability (private investment). This chapter offers an approach to 3P contract writing for HOV/HOT facilities that is structured by a stakeholder analysis of actors in the project accountability environment. By analyzing two Virginia 3P highway projects, the chapter shows it is possible to build into a contract a …

Disparities In Public Charging Infrastructure Deployment And Inequitable Electric Vehicle Ownership Cost Based On Income And Race, Chih-Wei Hsu

Cal Poly Humboldt theses and projects

Widespread electric vehicle (EV) adoption will be crucial for achieving decarbonization goals in California. The inclusion of marginalized populations in this process is important and involves challenges related to their physical access to charging infrastructure and economic access to EVs. Public access electric vehicle chargers (PAEVCs) and upfront financial incentives for EVs may help reduce the barriers affecting these populations. In this thesis, a spatial analysis at the census block group level shows that, in California, PAEVC access is lower in areas with below median household incomes and areas with a black and Hispanic majority. The PAEVC access disparities are …

Measuring Incremental Sb743 Progress: Accounting For Project Contributions Towards Reducing Vmt Under California's Senate Bill 743, Christopher E. Ferrell

Mineta Transportation Institute Publications

On September 27, 2013, California’s governor signed Senate Bill (SB) 743 into law, in part mandating the transition from a level-of-service-based (LOS) measure of transportation environmental impacts to a vehicle-miles-traveled-based (VMT) one in compliance with the California Environmental Quality Act (CEQA). Several California jurisdictions, including San Jose, Pasadena, and San Francisco, have moved quickly to comply with SB 743, so it is no surprise that several of these early-adopter cities have been working hard to develop powerful VMT estimation methods and tools using the most recent research available.

This perspective uses the experiences of an early-adopter city, San Jose, to …

The Resilient City: A Platform For Informed Decision-Making Process, Paul Niculescu-Mizil Gheorghe, Jarutpong Vasuthanasub, Adrian Gheorghe

Engineering Management & Systems Engineering Faculty Publications

As over half of the world’s inhabitants lives in metropolises, the rapid growth in urbanization has made cities becoming more and more exposed and vulnerable to a broad spectrum of threats and hazards. In order to respond to such difficulties, a concept of resilience is considered a significant component for the long-term planning and sustainable development of the cities. “Resilient City” is a new paradigm that challenges the idealistic principle of stability and resistance to change implicitly in sustainable development and success.

Access Points And Weave Lengths For Automated Truck Lanes At Two Closely Spaced Interchanges, Ximena Jauregui

Open Access Theses & Dissertations

The increase of traffic on major U.S. roadways has motivated the implementation of new technologies and better management of the transportation infrastructure, including managed lanes on freeways. Dedicated truck lanes, a type of managed lane, are increasingly attracting attention since truck freight is continuously increasing and trucks have greater impact on traffic flow relatively to cars. Truck-only managed lanes allow trucks to travel at their own speeds in an exclusive lane with no passenger vehicles on the way; likewise, vehicles on the main lanes of the freeway will have fewer trucks to travel with.

As truck-only managed lanes are being …
