Integrating Transportation Management Companies (TMCs) and Public Transportation

Emerging technologies have given rise to Transportation Management Companies (TMCs), which deliver on-demand services via a customer-facing smartphone app. The expansion of wireless communication technology promises continued growth for ride-sourcing, and presents both challenges and opportunities in integrating these services into the transportation system (Middleton, 2010). Currently, the primary work linking on-demand service to public transportation focuses on the provision of both first- and last-mile trips (Clifton and Muhs, 2012). This study analyzes an expanded role for integrating TMCs into public transit linking the public and private sectors and providing greater accessibility through increased connectivity and coordinated service delivery. This integration requires a framework that facilitates and supports a public-private partnership. The authors examine the potential impact of this integration on transit services in an American context. Selected benefits include enhanced transit ridership, expanded access to employment, cost savings, and new revenue opportunities for transit agencies and private TMCs. This project examines the benefits of on-demand ride service from three aspects: 1) The extent that on-demand TMC services influence job access, 2) How this job accessibility varies spatially across different populations, and 3) How the cost-effectiveness of TMC services compares to traditional transit and what funding mechanisms might improve synergies between the two. This study focuses on the City of Chicago, and explores the impact of TMCs on accessibility to jobs and other amenities. With assumptions about average wait time of TMCs ranging from 1 to 12 minutes, the results of different scenarios suggest that TMC availability and trip lengths that TMCs can be used are the two more dominating factors influencing the extent to which accessibility can be improved. The accessibility improvement is most significant for areas with lowest existing accessibility and has no obvious difference across different population subgroups. Lastly, policy implications and potential funding and financing strategies of realizing the accessibility and equity benefits of integrating TMCs with transit are discussed

A Multi-asset Transportation Infrastructure Asset Management Framework and Modeling for Local Governments

CTEDD 017-03Local governments (LGs) in the United States are managing 3/4 of 4 billion miles of roadway and more than 1/2 of nearly 600,000 bridges, which are critical transportation infrastructure assets that support the mobility, economy, and homeland security on both the local and national levels. To maintain the aging infrastructure in a state of good repair under shrinking budgets, LGs must adopt a systematic approach to conduct cost-effective maintenance, rehabilitation, and reconstruction (MR&R) instead of relying on subjective individual knowledge and experience. As a result, benefit from the scarce transportation budget could be maximized; and accountability could be demonstrated to the stakeholders

Evaluation of bicycle and pedestrian facilities : user satisfaction and perceptions on three shared use trails in Texas

87 p. Illustrations, MapsThis report describes research conducted to evaluate bicycle and pedestrian facilities (i.e., shared use trails) with user satisfaction and perception surveys. Public and community input on transportation projects is often mentioned as a necessary step in the planning process but seldom perfonned. The opinions and perceptions of facility users are immensely valuable in improving conditions at current trails as well as in the development and design of new trails. In this study, the research team developed on-site and mail-back survey instruments that were distributed on three shared use trails in Texas: the Brays and Buffalo Bayou Trails in Houston, and the Shoal Creek Trail in Austin. The responses to the surveys were analyzed to determine consistent themes and trends in user satisfaction and perceptions. The study found that several trail attributes contribute significantly to user satisfaction and higher levels of trail use. Adequate separation from motor vehicles was noted as a positive attribute that should be provided whenever possible on s~ed use trails. Trail surface quality and width was also noted as an important attribute, particularly in cases where numerous user types (e.g., bicyclists, joggers, walkers) were using the same trail. The study also revealed that many of the trail users felt that the shared use trails significantly contributed to hannonizing transportation and community goals. The survey responses indicated that the trails were used for a variety of purposes, including transportation, recreation, social interaction, and enjoyment of the natural environment. The researchers concluded that user surveys (such as those conducted in this study) are a valuable addition to other traditional transportation planning tools, and as such, can provide more and better insight into roadway and trail user behavior and motivation

Mitigating Traffic Congestion on I-10 in Baton Rouge, LA: Supply- and Demand-Oriented Strategies & Treatments [Supporting Dataset]

This study developed and calibrated a microsimulation model of I-10 (from Lobdell Highway in Port Allen to Highland Road, I-110 to Florida Street, and I-12 to Walker Road) and investigated several supply- and demand-oriented strategies. This includes: rehabilitation and utilization of the old Mississippi River Bridge on US-190 and the existing US-190/US-61 corridor, overall demand management of I-10 eastbound traffic, reduction in percent trucks traveling eastbound on I-10 during the A.M. peak period, and ramp metering at the on-ramp west of the I-10 Mississippi River Bridge. The majority of the tested strategies appear to be feasible and effective solutions; however, a combination of supply- and demand-oriented treatments must be implemented to fully relieve congestion on I-10 in Baton Rouge.The total size of the described file is 2.40 GB.
