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 em...

Affordable Housing Trip Generation Strategies and Rates
Kelly Clifton
Kristina Currans , Susan Handy , Robert Schneider
Assessment and mitigation of transportation impacts based on travel demand is required by state, federal, and local laws in California. Determining trip generation is typically the first step in preparing these transportation impact analyses, and current industry standard practice relies on trip rates published by the Institute of Transportation Engineers (ITE). However, ITE protocols emphasize vehicle trip rates without sensitivity to urban context or socioeconomic characteristics, which can...
