Automated Vehicles Have Arrived: What's A Transit Agency To Do?, John Niles 2019 Mineta Transportation Institute

Automated Vehicles Have Arrived: What's A Transit Agency To Do?, John Niles

Mineta Transportation Institute

Ongoing innovations in automated and connected road vehicles create a path of radical transformation of personal mobility, the automotive industry, trucking, public transit, the taxi industry, urban planning, transportation infrastructure, jobs, vehicle ownership, and other physical and social aspects of our built world and daily lives.

In considering automated vehicle (AV) deployments and their cost, as well as the changes in traffic volume, congestion, rights of way, and the complexities of mixed fleets with both automated and non-automated vehicles, the time frame of impacts can only be surmised.

Still, it is worth considering a framework for understanding and managing the …

The ultimate objective is to develop a new paradigm to define, describe, design, and deploy the most effective protection, at the lowest cost, in the shortest time within the limits of available resources. …


Measuring Incremental Sb743 Progress: Accounting For Project Contributions Towards Reducing Vmt Under California's Senate Bill 743, Christopher E. Ferrell 2019 Mineta Transportation Institute

Measuring Incremental Sb743 Progress: Accounting For Project Contributions Towards Reducing Vmt Under California's Senate Bill 743, Christopher E. Ferrell

Mineta Transportation Institute

On September 27, 2013, California’s governor signed Senate Bill (SB) 743 into law, in part mandating the transition from a level-of-service-based (LOS) measure of transportation environmental impacts to a vehicle-miles-traveled-based (VMT) one in compliance with the California Environmental Quality Act (CEQA). Several California jurisdictions, including San Jose, Pasadena, and San Francisco, have moved quickly to comply with SB 743, so it is no surprise that several of these early-adopter cities have been working hard to develop powerful VMT estimation methods and tools using the most recent research available.

This perspective uses the experiences of an early-adopter city, San Jose, to …


A State Aggregation Approach For Stochastic Multiperiod Last-Mile Ride-Sharing Problems, Lucas AGUSSURJA, Shih-Fen CHENG, Hoong Chuin LAU 2019 Singapore Management University

A State Aggregation Approach For Stochastic Multiperiod Last-Mile Ride-Sharing Problems, Lucas Agussurja, Shih-Fen Cheng, Hoong Chuin Lau

Research Collection School Of Computing and Information Systems

The arrangement of last-mile services is playing an increasingly important role in making public transport more accessible. We study the use of ridesharing in satisfying last-mile demands with the assumption that demands are uncertain and come in batches. The most important contribution of our paper is a two-level Markov decision process framework that is capable of generating a vehicle-dispatching policy for the aforementioned service. We introduce state summarization, representative states, and sample-based cost estimation as major approximation techniques in making our approach scalable. We show that our approach converges and solution quality improves as sample size increases. We also apply …


Routing And Scheduling For A Last-Mile Transportation System, Hai WANG 2019 Singapore Management University

Routing And Scheduling For A Last-Mile Transportation System, Hai Wang

Research Collection School Of Computing and Information Systems

The last-mile problem concerns the provision of travel services from the nearest public transportation node to a passenger’s home or other destination. We study the operation of an emerging last-mile transportation system (LMTS) with batch demands that result from the arrival of groups of passengers who desire last-mile service at urban metro stations or bus stops. Routes and schedules are determined for a multivehicle fleet of delivery vehicles, with the objective of minimizing passenger waiting time and riding time. An exact mixed-integer programming (MIP) model for LMTS operations is presented first, which is difficult to solve optimally within acceptable computational …

Capturing The Built Environment-Travel Interaction For Strategic Planning: Development Of A Multimodal Travel Module For The Regional Strategic Planning Model (Rspm), Liming Wang, Brian Gregor, Huajie Yang, Tara Weidner, Anthony Knudson

Urban Studies and Planning Faculty Publications and Presentations

Integrated land use and transportation models have evolved along a spectrum from simple sketch planning models to complex microsimulation models. While each has its niche, they are largely unable to balance the flexibility and realism of microsimulation and the speed and interactivity of simple models. The Regional Strategic Planning Model (RSPM) aims to fill this gap by taking a microsimulation approach while making other simplifications in order to model first-order effects quickly. It enables planners to consider the robustness of prospective policies in the face of future uncertainties by accepting a broad range of inputs and allowing rapid simulations of …


A Framework To Capture Dynamic Traffic Trends From Historical Sensor Data, Carlos Gaviria 2018 University of Nevada, Las Vegas

A Framework To Capture Dynamic Traffic Trends From Historical Sensor Data, Carlos Gaviria

UNLV Theses, Dissertations, Professional Papers, and Capstones

The typical approach of increasing infrastructure to alleviate traffic issues such as congestion is becoming unviable due to limited space, high cost, and associated externalities. Control and management strategies using Intelligent Transportation Systems (ITS) seek to maximize the use of existent infrastructure. Many ITS strategies, such as the deployment of information, require or benefit from knowledge about traffic patterns and trends. This study proposes a mathematical programming formulation and solution algorithm that considers multiple time intervals for the estimation of network-wide traffic states and calculation of the corresponding transition probabilities. The proposed solution enables the determination of sections of the …

Professional Sports, Hurricane Katrina, And The Economic Redevelopment Of New Orleans: Revisited, Victor Matheson, Robert Baade, Callan Henderschott

Economics Department Working Papers

Hurricane Katrina devastated the city of New Orleans in late August 2005, resulting in damage to much of the city’s sports infrastructure and the temporary departure of both of New Orleans’ major league professional sports teams, the National Football League Saints and the National Basketball Association Hornets. The city spent over $500 million restoring the sports infrastructure in New Orleans, and both teams subsequently returned to the city. In addition, New Orleans has since hosted numerous mega-sporting events including the Super Bowl, NCAA Men’s Basketball Final Four, and several college football national championships. This paper examines the economic impact of …

The Rise And Fall (And Rise And Fall) Of The Olympic Games As An Economic Driver, Victor Matheson

Economics Department Working Papers

This paper traces the economic history of major sporting events focusing on the Olympics. Historically, the Olympic Games as well as other major sporting events have been considered costly events that place a burden on host cities. Only in relatively recent years, coinciding with the massive increases in the cost of hosting these events, have event organizers begun to claim that these events bring with them large economic benefits.


Engaging Youth To Increase Their Transportation System Support, Understanding, And Use, Autumn Shafer, Jared Macary 2018 University of Oregon

Engaging Youth To Increase Their Transportation System Support, Understanding, And Use, Autumn Shafer, Jared Macary

TREC Final Reports

Little is known from research about how to motivate youth to choose non-car mobility, especially specific Portland-area youth. Understanding the current attitudes, beliefs, and behaviors of youth in relation to non-car mobility contributes to the sustainability of a long-term transportation system. Transportation system-related beliefs and behaviors of youth are likely to influence their willingness to access and support transportation services as adults. Today’s youth are tomorrow’s riders, bikers, walkers, voters, and transportation planners. Thus, it is important to develop age-appropriate messaging strategies and tactics that promote youth non-car mobility.

This project seeks to build on the sparse national and non-Portland …

Point/Counterpoint: Is There A Case For Subsidizing Sports Stadiums?, Victor Matheson 2018 College of the Holy Cross

Point/Counterpoint: Is There A Case For Subsidizing Sports Stadiums?, Victor Matheson

Economics Department Working Papers

In recent decades, governments have committed enormous public resources to subsidize construction of new stadiums, and the dollar value of taxpayer contributions for these subsidies continues to climb. Spending of taxpayer dollars includes both direct subsidies from state and local governments, as well as indirect subsidies from the use of tax-exempt bonds to finance construction. In granting stadium subsidies, governments claim that the stadiums are a public good that attracts tourists and businesses, thereby generating increased spending and job creation—benefits that flow to the community rather than to team owners. But do such benefits exist, and are they large enough …

China’S Belt And Road Initiative And Asean’S Maritime Cluster, Hans-Dieter Evers, Thomas Menkhoff

Research Collection Lee Kong Chian School Of Business

This paper centres around China’s Belt and Road Initiative (BRI) and makes a case for further examining the possible effects of the complementary ‘Maritime Silk Road’ on Southeast Asia’s maritime clusters with reference to Singapore, Malaysia and Indonesia. Port development with “Chinese engagement” from Port Klang in Malaysia to Sri Lanka to Gwadar in Pakistan to some Gulf state ports to Piraeus in Greece provides a string of valuable pearls in the form of harbours from which adjoining areas can be serviced through feeder vessels or railway lines by Chinese government-linked companies. Whether China’s heavy investments in land and maritime …
