Does Transit Service Reliability Influence Ridership?, Srinivas S. Pulugurtha, Raunak Mishra, Sravya L. Jayanthi Nov 2022

Does Transit Service Reliability Influence Ridership?, Srinivas S. Pulugurtha, Raunak Mishra, Sravya L. Jayanthi

Mineta Transportation Institute

This research focused on analyzing the association between transit service reliability indicators and ridership. Further, the effect of road network, demographic, socioeconomic, and land use characteristics on transit service reliability was analyzed. The analysis was conducted at a bus stop level. Bus arrival/departure and ridership data from the Charlotte Area Transit System (CATS) was obtained. The road network, demographic, socioeconomic, and land use characteristics were captured within 0.25-mile and 0.50-mile buffers. Pearson correlation analysis was conducted to understand the association between road network, demographic, socioeconomic, and land use characteristics and bus transit service reliability measures. The results show that bus …


Effect Of Weather Events On Travel Time Reliability And Crash Occurrence, Sonu Mathew, Srinivas S. Pulugurtha Nov 2022

Effect Of Weather Events On Travel Time Reliability And Crash Occurrence, Sonu Mathew, Srinivas S. Pulugurtha

Mineta Transportation Institute

The magnitude of the effect of adverse weather conditions on road operational performance varies with the type of weather condition and the road characteristics of the road links and adjacent links. Therefore, the relationship between weather and traffic is always a concern to traffic engineers and planners, and they have extensively explored ways to integrate weather information into transportation systems. Understanding the influence of weather on operational performance and safety helps traffic engineers and planners to proactively plan and manage transportation systems. The main objective of this research is to evaluate the effect of adverse weather conditions on travel time …


Exploring The Use Of Public Transportation Among Older Adults During The Covid-19 Pandemic: A National Survey, Keertana Sureshbabu, Egbe-Etu Etu, Susan Summerville, Ankur Parmar, Gaojian Huang Nov 2022

Exploring The Use Of Public Transportation Among Older Adults During The Covid-19 Pandemic: A National Survey, Keertana Sureshbabu, Egbe-Etu Etu, Susan Summerville, Ankur Parmar, Gaojian Huang

Mineta Transportation Institute

Public transportation is an essential part of many older adults’ lives, but the pandemic presented new challenges for the vulnerable population. Adults aged 65 years and older experienced additional challenges, such as limited mobility options (e.g., lack of buses or trains in service due a combination of government lockdowns, fear of contracting or spreading the virus, and driver shortages in certain areas) because of the pandemic, which may have resulted in more age-related declines in perceptual, cognitive, and physical functioning. This study explores how older adults living in major metropolitan cities in the United States used and perceived public transportation …


Ai-Based Pedestrian Detection And Avoidance At Night Using An Ir Camera, Radar, And A Video Camera, Hovannes Kulhandjian Nov 2022

Ai-Based Pedestrian Detection And Avoidance At Night Using An Ir Camera, Radar, And A Video Camera, Hovannes Kulhandjian

Mineta Transportation Institute

In 2019, the United States experienced more than 6,500 pedestrian fatalities involving motor vehicles which resulted in a 67% rise in nighttime pedestrian fatalities and only a 10% rise in daytime pedestrian fatalities. In an effort to reduce fatalities, this research developed a pedestrian detection and alert system through the application of a visual camera, infrared camera, and radar sensors combined with machine learning. The research team designed the system concept to achieve a high level of accuracy in pedestrian detection and avoidance during both the day and at night to avoid potentially fatal accidents involving pedestrians crossing a street. …


Spatio-Temporal Analysis Of Roadside Transportation-Related Air Quality (Startraq 2021): A Characterization Of Bike Trails And Highways In The Fresno/Clovis Area, Jaymin Kwon, Yushin Ahn, Steve Chung Nov 2022

Spatio-Temporal Analysis Of Roadside Transportation-Related Air Quality (Startraq 2021): A Characterization Of Bike Trails And Highways In The Fresno/Clovis Area, Jaymin Kwon, Yushin Ahn, Steve Chung

Mineta Transportation Institute

The San Joaquin Valley is identified as an area with a high level of particulate matter (PM) in the air, reaching above the federal and state clean air standards (EPA 2019). Many of the cities in the valley are classified as the most polluted cities in the United States for both particulate matter and ozone pollution (American Lung Association, 2021). To resolve this issue, alternative forms of transportation have been considered in transportation planning. In this study, active transportation mode air quality was monitored on selected Woodward Park and Old Clovis trails and urban bike lanes. Real-time aerosol monitors, and …


Fragmented Or Aligned Climate Action: Assessing Linkages Between Regional And Local Planning Efforts To Meet Transportation Greenhouse Gas Emissions Reduction Targets, Serena E. Alexander, Ahoura Zandiatashbar, Branka Tatarevic Nov 2022

Fragmented Or Aligned Climate Action: Assessing Linkages Between Regional And Local Planning Efforts To Meet Transportation Greenhouse Gas Emissions Reduction Targets, Serena E. Alexander, Ahoura Zandiatashbar, Branka Tatarevic

Mineta Transportation Institute

Amid the rising climate change concerns, California enacted Senate Bill 375 (SB 375) to tackle transportation greenhouse gas (GHG) emissions. SB 375 requires Metropolitan Planning Organizations (MPOs) to develop a Sustainable Communities Strategy (SCS), a regional transportation and land use vision plan, to reduce GHG emissions. Meanwhile, a local government can develop a Climate Action Plan (CAP), a non-binding, voluntary plan to reduce GHG emissions that may align with the regional SCS. Recent progress reports indicate California is not making sufficient progress to meet SB 375 emissions reduction targets, which raises important questions: (1) Are the transportation and land use …

Understanding The Role Of Transportation In Human Trafficking In California, Kezban Yagci Sokat Nov 2022

Understanding The Role Of Transportation In Human Trafficking In California, Kezban Yagci Sokat

Mineta Transportation Institute

Human trafficking, a form of modern slavery, is the recruitment, transport, and/or transfer of persons using force, fraud, or coercion to exploit them for acts of labor or sex. According to the International Labor Organization, human trafficking is the fastest growing organized crime with approximately $150 billion in annual profits and 40.3 million individuals trapped in slave-like conditions. While it is not compulsory to involve transportation for human trafficking, the transportation industry plays a critical role in combating human trafficking as traffickers often rely on the transportation system to recruit, move, or transfer victims. This multi-method study investigates the role …

Large Eddy Simulations Of Wind Shear From Passing Vehicles Under A Freeway Overpass, Hamid Rahai, Assma Begum Oct 2022

Large Eddy Simulations Of Wind Shear From Passing Vehicles Under A Freeway Overpass, Hamid Rahai, Assma Begum

Mineta Transportation Institute

California is moving toward a 100% clean energy future, and expanded wind energy will be a major component of the state’s future energy portfolio. Innovations in wind energy resources will move California closer to achieving its goal. To gain a better understanding of transient pressure and the wind shear generated at the bridge poles from passing vehicles, this study performed large-eddy simulations of a vehicle (also called an Ahmed body) moving under a freeway overpass at a distance of 0.75 w (width) from the bridge poles. Results include transient contours of mean velocity, turbulent kinetic energy, vorticity, and pressure around …
