PROJECT OBJECTIVE: To help federal and state agencies
to identify effective safety programs for reducing truck accidents.
MODAL ORIENTATION: Highways
PROJECT ABSTRACT: During the past decades, the increased
activities in urban, rural, and global goods movement and the
recent boom in intermodal transportation have lead to tremendous
growth in truck traffic as well as the safety concerns associated
with such growth. Various truck safety programs have been implemented
across the United States to curb these seemingly ever-worsening
truck safety problems. This study represents a joint effort of
the researchers at the University of Tennessee, Knoxville, and
the University of Kentucky to assess the impact and effectiveness
of these truck safety programs.
MILESTONES, DATES: To begin and finish the proposed
study, including final report and presentation on time.
BUDGET: Total budget is $122,999.
STUDENTS: Four graduate research students, three
of which are minorities.
T2 ACTIVITIES: Technology Transfer: Copies
of the final report will be sent to federal, state, and local
agencies; a technical paper will be prepared for presentation
and publication at TRB, ITE or ASCE conferences; a one-page summary
will be prepared for circulation among public and private transportation
agencies and companies; presentation or seminars can be arranged
for face-to-face technology transfer opportunities.
POTENTIAL BENEFITS: A measure of the effectiveness
of various safety programs aimed at reducing truck accidents
will enable transportation agencies to evaluate the most beneficial
programs given limited resources.
TASK DESCRIPTION:
1. Conduct a comprehensive literature
review to identify the state-of-the-practice and reserach activities
related to the proposed study.
2. Collect truck accident data, safety program
information, and traffic and exposure data.
3. Data Analysis I. Analyze data, to be carried
out in two parts. The first part involves using statistical
analysis procedures.
4. Data Analysis II. The second part will evaluate
the impact of safety inspection practice as a function of "microscopic
changes" in existing safety programs.
5. Prepare final report and presentation.
