California’s Freeway Service Patrol Program Management: Information System Annual Report Fiscal Year 2004-05

Mauch, Michael
Skabardonis, Alex
2007

The Freeway Service Patrol (FSP) is an incident management program implemented by Caltrans, the California Highway Patrol and local partner agencies to quickly detect and assist disabled vehicles and reduce non-recurring congestion along the freeway during peak commute hours. The first FSP program was piloted in Los Angeles, and was later expanded to other regions by state legislation in 1991. As of June 2005, there were ten participating FSP Programs operating in California, deploying over 315 tow trucks and covering over 1,500 (center-line) miles of congested California freeways.The...

Shared mobility services have now become firmly integrated into urban transportation systems across the globe. Carsharing, bikesharing, ridesourcing or transportation network companies(TNCs), and other systems now offer urban travelers access to transportation services that had long been previously only possible through personal vehicle ownership. Carsharing is arguably the pioneer mode of the sharing economy, given it ushered in a new way of thinking and access to the private automobile in the 20thcentury.Since its North American inception in Montreal in 1994, carsharing has undergone...

Preserving Privacy in Road User Charge (RUC) Architectures

Bayen, Alexandre, PhD;
Forscher, Teddy
Shaheen, Susan, PhD
2018

One of the major concerns for the technical implementation of a RUC is the ability to collect the mileage of motorists in a way that preserves and protects individual privacy. With the widespread use of connected devices/smartphones and the growth of connected vehicles and the existence of toll tag readers, it is possible to build and deploy architectures capable of computing advanced fee structures (based upon on mileage, road type, time of day, and speed, among other features) that respect motorist privacy. A possible architecture can rely on the use of virtual trip lines (VTLs) –a...

Impacts of Shared Mobility

Shaheen, Susan, PhD
Cohen, Adam
2018

Shared mobility modes have reported a number of environmental, social, and transportation-related impacts. Several studies have documented the reduction of vehicle usage, ownership, and vehicle miles traveled (VMT). Cost savings and convenience are frequently cited as popular reasons for shifting to a shared mode. Shared modes can also extend the catchment area of public transit, potentially playing a pivotal role in bridging gaps in existing transportation networks and encouraging multi-modality by addressing the first-and-last mile issue related to public transit access (1). Shared...

Pooling Passengers and Services

Forscher, Teddy
Shaheen, Susan, PhD
2018

In the past ten years, passenger and goods movement transportation systems have evolved rapidly. Shared mobility providers are filling gaps in service and creating new markets for delivery; vehicle fleets continue to electrify; and pooled services are increasing vehicle occupancy. The uptake of innovative pooled services, as well as automation, promise to continue the trend of transformative change. As the private sector continues to advance, there is a great need for institutional flexibility in managing and coordinating all users of transportation infrastructure, particularly on the...

Overview of Shared Mobility

Shaheen, Susan, PhD
Cohen, Adam
2018

Shared mobility—the shared use of a vehicle, bicycle, or other travel mode—is an innovative transportation strategy that enables users to have short-term access to a transportation mode on an as-needed basis (1). Shared mobility includes various service models and transportation modes that meet diverse traveler needs. Shared mobility can include roundtrip services (vehicle, bicycle, or other travel mode is returned to its origin); one-way station-based services (vehicle, bicycle, or other mode is returned to a different designated station location); and one-way free-floating services (...

Shared Mobility Policies for California

Shaheen, Susan, PhD
Cohen, Adam
2018

In recent years, economic, environmental, and social forces have quickly given rise to the “sharing economy,” a collective of entrepreneurs and consumers leveraging technology to share resources, save money, and generate capital. Shared mobility—the shared use of a vehicle, bicycle, or other low-speed travel mode—is an innovative transportation strategy that enables users to have short-term access to a transportation mode on an as-needed basis. Business-to-consumer services, such as Zipcar and car2go, and peer-to-peer carsharing and shared ride services, such as Getaround, Turo, Lyft, and...

What Can You Do with a County Road that You Can’t Afford to Maintain?

Jones, David
2017

Many rural county road networks were created at a time when funding was greater and rural populations were often larger than they are today. Eventually, surface treatments such as chip seals or thin asphalt were applied to many of these gravel roads to provide them with an all‐weather surface. These treated surfaces were also desirable because conventional gravel roads are dusty, often develop wash boarding quickly, and have high rates of gravel loss—which result in unsafe and uncomfortable conditions and greater damage to vehicles and crops. A solution to this problem is called ‘unpaving...
