Transportation Policy
Permanent URI for this collection
The transportation policy collection includes a series of research reports, white papers, and proceedings of public policy forums that have focused on transportation policy and infrastructure issues, including mobility friendly design, interconnectivity, healthy/walkable communities, transit-oriented development, integration of transportation/transit planning and land-use planning, Northeast Corridor transportation policy and infrastructure issues—particularly freight movement, and transit studies—including paratransit, specialized transportation, and bus rapid transit.

Item Bicycle Justice or Just Bicycles? Analyzing Equity in Baltimore's Bike Share Program(Department of Transportation and Urban Infrastructure at Morgan State University, 2018-09) Barnes, Philip J.; Grasso, Susan; Chavis, Celeste; Bhutan, Istiak A.; Nickkar, AmirrezaBike share systems have become a common feature of the modern urban landscape and provide residents and visitors with an active transportation mode. Yet these systems have sustained equity-focused criticism for serving a narrow demographic band of residents and visitors, while others lack access and face barriers to usage. The City of Baltimore, Maryland, launched a bike share system in 2016. This study evaluates Baltimore’s new system from an equity-focused lens using two complementary approaches. The first approach, which is a GIS-based equity gap analysis, develops a population-density-normalized Bike Equity Index to quantitatively assess the spatial distribution of the city’s bicycle infrastructure supply and how it serves (or doesn’t serve) Baltimore’s transit-dependent and environmental justice communities. The second analytic orientation, which applies a user and barrier analysis, utilizes survey data to identify the low-equity groups and the variables that limit (or don’t limit) their demand for the city’s bike share program. When combined, the two perspectives—one top-down and the other bottom-up—present a more comprehensive picture and nuanced understanding of the current system’s equity performance. The research findings demonstrate that Baltimore Bike Share infrastructure is unevenly distributed across the city’s many communities and is undersupplied in areas with residents who are transit-dependent. Furthermore, the results support claims of a demographic mismatch between current bike share system users and the general population. The communities underrepresented among Baltimore Bike Share users are less educated, lower-income, non-whites, Hispanics, and females. The research indicates that females express concern over certain barriers to accessing and using Baltimore Bike Share, including how to use the system, personal safety, helmet use, harassment, and hygiene. No significant barriers were identified for the other underrepresented demographic groups. To enhance the equity of the system, the research team recommends that the City of Baltimore prioritize bike share system expansion into the neighborhoods east and west of the downtown corridor. A robust community outreach strategy that targets underrepresented populations is also recommended and should include initiatives such as a grassroots bike share ambassador program and organized community rides. The bike share docking stations can also be leveraged for their advertising potential and should contain marketing materials that speak directly to underrepresented communities.Item Enhanced Mobility from Connected and Automated Vehicles(Institute for Public Administration, 2018-10) Barnes, Philip J.; Swan, BrettHow CAVS can enhance independent mobility options for the elderly and people with disabilities.Item Fiscal Impacts of Connected and Automated Vehicles in Delaware(Institute for Public Administration, 2018-10) Barnes, Philip J.; Swan, BrettHow Connected and Automated Vehicles will alter the state and municipal fiscal landscape.Item High Definition Mapping and Data Needs for Connected and Automated Vehicles(Institute for Public Administration, 2019-01) Barnes, Philip J.; Swan, BrettHigh-definition (HD) maps are essential for the safe operation of connected and automated vehicles (CAVs). The maps are not the traditional two-dimensional paper or GPS versions we are familiar with, but rather are three-dimensional representations of the real world—such as we see with our own eyes. HD maps, which come within centimeters of accuracy, allow a CAV to understand its location, surrounding physical environment, and rules of the road. Due to the complexity and data-intensity of HD maps, CAVs require extensive on-board computing power to quickly collect, store, process, and transmit a tremendous amount of data.Item Privacy in Connected and Automated Vehicles(2018-05) Barnes, Philip J.Today’s vehicles are packed with technologies that control, monitor, and record a variety of information. Data points include speed, acceleration, braking, geolocation, tire pressure, engine diagnostics, and the radio station. When connected and automated vehicles (CAVs) arrive in the coming years, the volume of data generated by automotive technology will increase further. CAVs, along with their infotainment displays, will substitute for the smartphone in your pocket and will be equally functional as data generators and receivers. As with smartphones, CAVs will create privacy and consumer protection concerns.
