A Gravity Model Integrating Land-Use And Transportation Policies For Sustainable Development: Case Study Of Fresno, California, Chih-Hao Wang, Na Chen

Mineta Transportation Institute

The idea of urban compaction has been long proposed and promoted to address the problem of urban sprawl in many American cities. However, there are still rare successful cases of such implementation in the United States. This study uses a classic gravity model, TELEM (Transpiration, Economic, and Land-Use Model) to examine to what extent a land-use or transportation policy must be regulated to make the urban compaction occur in a typical auto-dependent city—Fresno, California. Five scenarios are considered (BL, L1, L2, T1, and T2), in which the baseline (BL) is a natural growth scenario. Without any policy interventions, the city …

Rural Gentrification And The Spillover Effect: Integrated Transportation, Housing, And Land Use Challenges And Strategies In Gateway Communities, Danya Rumore, Philip Stoker

TREC Final Reports

Small towns and cities near national parks, public lands, and other natural amenities throughout the West are experiencing rapid growth and increased visitation. These “gateway communities” comprise a significant portion of the rural West, constituting about 31% of all communities and more than 60% of those under 25,000 people. Our prior NITC-funded research shows that growth and increased tourism create a range of “big city challenges” for gateway communities, particularly a significant increase in housing prices, which pushes the local workforce to outlying areas and other rural communities. As a result, despite being small towns, many developed gateway communities have …

Planning, Preserving, And Increasing Accessibility: A Reflection On Going “Car-Free”, Abigail J. Weizer

City and Regional Planning

This paper studies the accessibility of car-free areas to those with mobility impairments by examining three car-free and car-lite experiments in California. Whether slowly converted to car-free with long-term, careful planning, or expeditiously changed to car-free during the COVID-19 pandemic, these three car-free experiments show the shortcomings of planning for accessibility in car-free spaces, and how instead of improving accessibility, current planning practice often hinders it. This paper offers a deep-dive into the drawbacks and benefits of going car-free and the ethical and legal reasons why urban planners, designers, and policymakers must consider the accessibility of a space before planning …

Bike-Sharing Station Usage And The Surrounding Built Environments In Major Texas Cities, Louis G. Alcorn, Junfeng Jiao

Research Collection College of Integrative Studies

This study analyzes the effect of different built environments on bike-share usage in nascent dock-based systems in three Texas cities. Past research offers little insight as to whether elements associated with higher bicycle usage in major cities affect ridership in secondary, developing bike-share markets within lower density American cities. In Austin and Houston, a positive relationship emerges between bike-share usage and proximity to high-comfort bicycle facilities. All three cities demonstrated surprisingly minimal relationship between bike-share usage and other proven drivers of bicycling activity in urban areas, which may result from system design for leisure- and recreation-based trips.

Optimal Pricing Strategy For Electric Vehicle Battery Swapping: Pay-Per-Swap Or Subscription?, Xu Hu, Zhaojun Yang, Jun Sun, Yali Zhang

Information Systems Faculty Publications

Electric vehicles (EVs) contribute to carbon emission reduction, but the limitations of existing charging technologies impose a bottleneck to their further diffusion. Addressing the root issues of long waiting time and range anxiety, battery swapping demonstrates great market potential. A swapping service provider may choose between two pricing strategies based on battery rental: pay-per-swap and subscription. This study establishes a game-theoretical model to portray a simplified EV replenishment market including one charging station, one swapping station, and one battery renter, and explores the optimal pricing strategy. To capture the influence of consumer preferences, the model considers high versus low opportunity …

Pedestrian Behavior Study To Advance Pedestrian Safety In Smart Transportation Systems Using Innovative Lidar Sensors, Taylor Li, Sirisha M. Kothuri, Katherine L. Keeling, Xianfeng Terry Yang, Farzana R. Chowdhury

TREC Final Reports

Pedestrian safety is critical to improving walkability in cities. Although walking trips have increased in the last decade, pedestrian safety remains a top concern. In 2020, 6,516 pedestrians were killed in traffic crashes, representing the most deaths since 1990 (NHTSA, 2020). Approximately 15% of these occurred at signalized intersections where a variety of modes converge, leading to the increased propensity of conflicts. Current signal timing and detection technologies are heavily biased towards vehicular traffic, often leading to higher delays and insufficient walk times for pedestrians, which could result in risky behaviors such as noncompliance. Current detection systems for pedestrians at …

Network Effects Of Disruptive Traffic Events, Juan Medina, Xiaoyue Cathy Liu

TREC Final Reports

Current traffic management strategies are based on expected conditions caused by recurring congestion (e.g., by time of day, day of week), and can be very effective when provisions are also given for reasonable variations from such expectations. However, traffic variations due to non-recurrent events (e.g., crashes) can be much larger and difficult to predict, making also challenging efforts to identify, measure, and forecast their disruptive effects. This project explores a proactive approach to deploy a tool for managing non-recurrent congestion by identifying and quantifying the effects of disruptive traffic events at a microscopic level using a comprehensive set of data …
