Can Rebates Foster Equity in Congestion Pricing Programs?

Sallee, James M.
Tarduno, Matthew A.
2022

Congestion pricing improves economic efficiency, but it may lead to inequitable outcomes. A key policy priority in California is identifying ways to avoid the hardship of congestion pricing on low income or other vulnerable populations. This study uses data from a congestion pricing experiment in the Seattle metro area to examine the feasibility of using revenue from congestion pricing to compensate those harmed by the policy. Results indicate that the initial burden of congestion pricing is highly inequitable, with the lowest income drivers paying an average of 7 percent of their weekly...

A Dozen Reasons for Raising Gasoline Taxes

Wachs, Martin
2003

Motor fuel taxes at state and federal levels have traditionally been earmarked for transportation investments, supporting road construction, maintenance, and operations, and increasingly public transit. Recently, elected officials have been reluctant to raise fuel taxes despite increases in the cost of transportation programs. Other forms of support, especially borrowing and local sales taxes are playing larger roles in transportation finance. Raising fuel taxes would be more effective, efficient and equitable than the alternatives that are increasingly more popular.

Vehicle Manufacturing Futures in Transportation Life-cycle Assessment

Chester, Mikhail
Horvath, Arpad
2011

Vehicle manufacturing effects are critical life-cycle components in the total costs of vehicle travel and future manufacturing processes should be evaluated for travel forecasts. With efforts to introduce lightweight materials, increased fuel economy, and new technologies such as electric vehicles, understanding the energy and environmental effects of these expected vehicles is critical. Current vehicle manufacturing energy use and greenhouse gas emissions are summarized from existing research for passenger (conventional gasoline vehicles, hybrid electric vehicles, aircraft, high-speed...

Examining the Potential for Uber and Lyft to be Included in Subsidized Mobility Programs Targeted to Seniors, Low Income Adults, and People with Disabilities

Deakin, Elizabeth, SM., J.D.
Halpern, Jeremy
Parker, Madeleine
2020

Public agencies have subsidized taxi rides for people who have difficulty driving a car or using the regular transit system – targeting older residents and people with disabilities. There is interest among public agencies to add transportation network companies (TNCs), such as Uber and Lyft, to subsidized ride programs as a travel option due to the widespread availability of TNCs and high-quality service. Key issues include the need for wheelchair accessible vehicles, subsidy needs, and clients who lack or are uncomfortable using a smartphone and credit card. This research included a...

Toll Pricing “Futures” Market Could Reduce Congestion and Increase Revenue

Fournier, Nicholas, PhD
Patire, Anthony, PhD
Skabardonis, Alexander
2024

Transportation agencies are increasingly relying on tolls to raise revenue and to mitigate congestion, but conventional fixed tolls do not necessarily encourage offpeak use of infrastructure, and high tolls can dampen economic productivity. Dynamically adjusting pricing based on demand can incentivize travelers to avoid peak traffic periods and shift it to other modes, but 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...

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...

COVID-19 has Significantly Impacted the Mobility and Activities of the Senior Population in Contra Costa County

Ragland, David R.

2020

Meeting the mobility needs of an aging population is one of the most substantial challenges facing California in the coming decades. The number of residents age 60 and above will grow to 13.9 million by 2050, representing over 25% of the state population. Meanwhile, the number of residents age 85 and above is expected to increase by over 70% between 2010 and 2030. In 2018, the Safe Transportation Research and Education Center (SafeTREC) at UC Berkeley conducted a survey on transportation mobility issues among older adults in Contra Costa County in California. Results indicated, among other...

Policy Brief: Social Equity Impacts of Congestion Management Strategies

Shaheen, Susan, PhD
Stocker, Adam
Meza, Ruth
2019

To better understand the equity implications of a variety of congestion management strategies, researchers at the Transportation Sustainability Research Center (TSRC) at University of California, Berkeley analyzed existing literature on congestion management strategies and findings from 12 expert interviews. The literature review applies the Spatial – Temporal – Economic – Physiological – Social (STEPS) Equity Framework1 to identify impacts and classify whether social equity barriers are reduced, exacerbated, or both by a particular strategy. The congestion management strategies of...

Leveraging the Sharing Economy to Expand Shelter and Transportation Resources in California Evacuations

Wong, Stephen
Shaheen, Susan
2019

In 2017 and 2018, California was severely impacted by a number of devastating wildfires that required thousands of people to evacuate. These evacuations were hampered by poor communication, traffic congestion, and transportation and shelter resource deficiencies. To ensure that all citizens have both transportation and shelter in evacuations, agencies must consider alternative strategies for expanding resources, such as leveraging the sharing economy. To understand the possibility of leveraging the sharing economy to provide housing and transportation in an evacuation, researchers at the...

Congestion Pricing Can Be Equitable If a Portion of the Revenue is Returned to Drivers

Sallee, James, PhD
Tarduno, Matthew, PhD
2003

Economists have long argued in favor of congestion pricing, under which drivers pay a fee or toll to enter roadways during peak times. An increasing number of global cities have adopted or are considering pricing programs. Even so, these regimes remain relatively rare and controversial. One key concern with congestion pricing is fairness. Road pricing can pose a substantial burden for low-income drivers, many of whom have little option to avoid travel during peak times and limited opportunity to choose other modes of travel. Prior research has shown that congestion pricing regimes tend to...
