Summary
This document is a compendium of research papers produced by undergraduate students in the 2007 Undergraduate Transportation Scholars Program at Texas A&M University. Sponsored by the Southwest Region University Transportation Center and the Texas Transportation Institute, the ten-week summer program allows civil engineering students to conduct sponsored transportation research under faculty mentorship. The report aggregates findings from four distinct studies addressing trip generation for mixed-use developments, pedestrian sign perception in work zones, driver compliance with work zone speed limits, and nighttime guide sign standards. The first paper, authored by Matthew Ciarkowski, analyzes trip generation and internal trip capture for mixed-use developments. The study addresses the need for accurate traffic impact data as compact, urban-style mixed-use sites become more prevalent. Ciarkowski conducted surveys at Legacy Town Center in Plano, Texas, utilizing cordon counts, door counts, and on-site interviews during peak morning and evening hours. This data was compared with existing datasets from Mockingbird Station (Dallas) and Atlantic Station (Atlanta) and benchmarked against Institute of Transportation Engineers (ITE) Trip Generation Handbook estimates. The methodology involved calculating expansion factors to adjust interview data to total door counts and determining internal capture rates, which represent the percentage of trips generated and absorbed within the site rather than entering the external street network. Ciarkowski’s results indicate that current ITE techniques for estimating trip generation are fairly accurate for mixed-use developments. Legacy Town Center showed an 8% error rate in morning estimates and a 3% error rate in evening estimates, whereas Mockingbird and Atlantic Stations exhibited higher discrepancies, partly due to unique site features like grocery stores or transit walk-throughs. The study found that internal capture rates typically range between 20% and 30%, with retail, restaurant, and residential uses consistently generating significant internal trips. The findings suggest that while ITE methods are valid, more data collection is necessary to strengthen relationships between site characteristics and capture rates. The compendium also includes three other studies. Nathan Fluker examined pedestrian and motorist perceptions of pedestrian signs in work zones. Jason Richter analyzed driver compliance with work zone speed limits. Marc Sandhu investigated nighttime driver needs, assessing current guide sign standards and identifying areas for improvement. Collectively, these papers provide preliminary data and insights into specific transportation engineering challenges, contributing to the broader body of knowledge supported by the University Transportation Centers Program. The report emphasizes that the findings reflect the students' summer activities and should be considered preliminary rather than definitive policy recommendations.
