Dashboard Cameras Combined with AI Provide an Affordable Method for Identifying Curb Usage

Arcak, Murat
Kurzhanskiy, Alexander
2024

The increasing reliance on transportation network companies (TNCs) and delivery services has transformed the use of curb space. The curb space is also an important interface for bikeways, bus lanes, street vendors, and paratransit stops for passengers with disabilities. These various demands are contributing to a lack of parking, resulting in illegal and double-parking and excessive cruising for spaces and causing traffic disturbance, congestion, and hazardous situations. How cities manage this public asset to support safety and the local economy relies on first understanding the usage...

The Benefits and Challenges of Incorporating Uber and Lyft in Subsidized Ride Programs that Serve Vulnerable Populations

Halpern, Jeremy
Deakin, Elizabeth
Parker, Madeleine
2020

Cities, transit agencies, and social service providers across the U.S. have implemented programs that provide taxi subsidies for people who have difficulty driving a car or using the regular transit system. These programs usually serve older residents and people with disabilities, though a few also serve low income users. Taxi subsidy programs provide curb-to-curb or door-to-door transportation at a fraction of the cost of paratransit.1 However, as Transportation Network Companies (TNCs), such as Uber and Lyft, have entered markets around the country, taxi availability has declined,...

Where are Private “Smart City” Transportation Technologies Concentrated in California?

In recent years, “smart city” information and communication technologies have proliferated. For local government agencies, procuring and introducing these technologies offers the possibility to manage infrastructure assets more effectively, plan for preventive maintenance, and disseminate schedules and information about transit and other services. Many of these technologies are deployed by private firms in the context of local regulations and government-sponsored incentives. In the transportation sector, examples of “smart city” technology services provided by private firms include:...

Role of Trust and Compassion in Willingness to Share Mobility and Sheltering Resources in Evacuations: A Case Study of the 2017 and 2018 California Wildfires

Wong, Stephen D.

2020

Advances in the sharing economy – such as transportation network companies (e.g., Lyft, Uber) and home sharing (e.g., Airbnb) – have coincided with the increasing need for evacuation resources. While peer-to-peer sharing under normal circumstances often suffers from trust barriers, disaster literature indicates that trust and compassion often increase following disasters, improving recovery through additional resources and support. We hypothesize that trust and compassion could trigger willingness to share transportation and sheltering resources during an evacuation.

Peer-To-Peer (P2P) Carsharing: Understanding Early Markets, Social Dynamics, and Behavioral Impacts

2018

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...

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...

Impacts of Shared Mobility: Pooling

Shaheen, Susan, PhD
Cohen, Adam
2018

Shared-ride services—transportation modes that allow riders to share a ride to a common destination—include various forms of ridesharing (carpooling and vanpooling); ridesplitting and taxisplitting; and microtransit. With the proliferation of smartphones and mobile Internet, it has become more convenient to share rides. Shared-ride services are having a transformative impact on many global cities by increasing vehicle occupancy through smartphone apps. Empirical and anecdotal evidence indicates that pooling provides numerous benefits, such as reductions in energy consumption and emissions...
