Evaluating Mobility Impacts Of Construction Workzones On Utah Transportation System Using Machine Learning Techniques
Abbas Rashidi
Roadside construction – be it a detour, a closed lane, or a slow weave past workers and equipment – work zones impact traffic flow and travel times on a system-wide level. The ability to predict exactly what those impacts will be, and plan for them, would be a major help to both transportation agencies and road users. Funded by the National Institute for Transportation and Communities, the latest Small Starts project led by Abbas Rashidi of the University of Utah introduces a robust, deep…

Evaluation of an Eco-driving Intervention: Changing Knowledge, Attitudes, and Behavior by Means of Supervisor Support
Donald Truxillo John MacArthur , Leslie Hammer , Talya N. Bauer
Past eco-driving research has looked at the effectiveness of various eco-driving programs, but the role supervisor and organizational support have remained unexamined. This is unfortunate, as support from the supervisor and the organization have consistently been shown to determine whether or not employee interventions (e.g., training, safety) are effective (e.g., Christian et al. 2009; Salas et al., 2012). In other words, supervisor and organizational support are important for translating…
