Developing An Roi Assessment Model For Employee Development Programs Implemented By California Transit Agencies, Tyler Reeb, Susan Gallagher

Mineta Transportation Institute

The objective of this research is to determine the extent to which transit agencies in California are implementing Return on Investment (ROI) assessments or otherwise evaluating the value and effectiveness of the employee development programs they administer, what cost and performance data they collect and track, and what resources or support are needed to support ROI assessment efforts. Transit agencies will necessarily incur expenses in efforts to improve the recruitment, retention, and morale of employees, but will struggle to solicit adequate funding unless they are able to demonstrate the value of such efforts to a broader audience. Thus, developing and …

The Indirect Benefits Of A Transit Apprenticeship And Its Potential Value As A Flexible Postsecondary Pathway, Kathleen F. Mcconnell, Priya Raman

Mineta Transportation Institute

The transit sector has begun to embrace apprenticeships as a worthwhile training model. Apprenticeships may also address young people’s interest in career advancement opportunities, an additional benefit to the transit sector as it replaces an aging workforce and resolves other recruitment challenges. Apprenticeships that emphasize both technical and soft skills invest in career advancement by offering employees the chance to develop “cross-cutting competencies.” A highly developed model of this approach is found in the Santa Clara Valley Transportation Authority Joint Workforce Initiative (JWI), which formally recognizes skills acquisition with accredited certificates. Further development of this model would find support in …

Experimental Investigations Of Wind Shear From Passing A Vehicle, Hamid Rahai, Assma Begum, Jeremy Bonifacio, Ryan Moffit

Mineta Transportation Institute

Wind energy can be harnessed for various commercial and transportation-related applications. This study assessed experimentally the potential of capturing wind energy from the passage of vehicles for electric power generation. Both wind tunnel experiments and field tests were performed. The wind tunnel experiments were performed in an open-circuit low-speed wind tunnel at a free-stream mean velocity of 23 m/s. Five PVC pipes placed adjacent to the wind-blowing domain were used to simulate the columns under a freeway overpass. A scaled Ahmad body (simplified car body model) was used as the vehicle. The spanwise distance between the Ahmad body and the …

Right Turn On Red: Energy-Saving Measure Or Unsafe Maneuver?, Bruce Appleyard, Anurag Pande, Joseph Gibbons, Shams Tanvir, Megan Honey, Nell Ahangarfabrik, Mario Carbajal, Madison Swayne

Mineta Transportation Institute

There is a growing interest in prohibiting right turn on red (RTOR) policies in the name of pedestrian and bicycle safety but there is not enough research on the subject to help agencies make informed decisions. When Congress passed the Energy Policy and Conservation Act of 1975, they included a provision requiring states to permit right turns on red lights as an energy-saving measure to receive federal assistance for mandated conservation programs. Since 1980, all states have permitted right turns on red as a general rule. More research is needed to help guide state policies that can support jurisdictions in …

Uncovering Electric Vehicle Ownership Disparities Using K-Means Clustering Analysis: A Case Study Of Austin, Texas, Seung Jun Choi, Junfeng Jiao

Research Collection College of Integrative Studies

Transportation electrification is promoted for its environmental and energy efficiency benefits. However, recent studies examining electric vehicle (EV) adoption have revealed complex patterns influenced by race and income disparities. These studies, primarily based on surveys, often overlook regional ownership variations and built environment measures linked to urban form. Our study addresses this gap by analyzing actual EV registration data with spatial details using hot spot and K-means clustering analyses. The analysis results revealed a pronounced East–West divide in EV adoption. In West Austin, clusters indicate a higher number of EVs, greater energy consumption, and residents who are predominantly White, with …

Bike Buses: An Evaluation Of An Emerging Active Transportation To School Intervention, Evan Howington, Nathan Mcneil, John Macarthur

TREC Faculty and Staff Publications

Bike buses are a relatively new form of active transportation to school (ATS) that have primarily emerged in Europe and the United States. A form of coordinated, group bike riding along a defined route to school, bike buses are an outgrowth of Safe Routes to School interventions in North America that seek to reverse the declining rates of walking and biking to school among children. Our initial phase of research included a literature review of social and environmental factors affecting ATS in the contemporary North American context, and two convenience surveys of bike bus coordinators and parent participants. This initial …

Ev Charging At Multifamily Properties: Moving Beyond Barriers, Whit Jamieson, Anna Guida, Connor Herman

PSU Transportation Seminars

Transportation is the top contributor of greenhouse gas emissions in the US and light-duty vehicles are the #1 contributor to transportation emissions. Mass adoption of electric vehicles (EVs) is key in the fight toward a more sustainable future, but there are several factors that have delayed our transition to EVs.

EV charging at home is the most convenient and cost-effective charging option for EV drivers, but people living in multifamily housing face serious barriers to accessing home charging. During this session, we will explore why EV charging at multifamily housing is critical to mass adoption of EVs, barriers to charging …
