This report is a compilation of research papers written by students participating in the 2011 Undergraduate

Transportation Scholars Program. The 10-week summer program, now in its 21st year, provides

undergraduate students in Civil Engineering the opportunity to learn about transportation engineering

through participating in sponsored transportation research projects. The program design allows students to

interact directly with a Texas A&M University faculty member or Texas Transportation Institute researcher

in developing a research proposal, conducting valid research, and documenting the research results through

oral presentations and research papers.

The papers in this compendium report on the following topics, respectively: 1) evaluating the impact of

nighttime work zone lighting characteristics on motorists; 2) late night roadway visibility; 3) investigation

of the use and pricing of the I-15 express lanes in San Diego; 4) intercity passenger rail access to airports: a

case study at the Milwaukee airport; 5) development of a background complexity assessment tool;

6) identifying pavement preservation treatments suitable for performance-related specifications; and

7) arsenic content and retroreflectivity of glass beads used in pavement markings.
