Crime Prevention for Truckers Study
DTMC75-14-D-00008LThe Federal Motor Carrier Safety Administration (FMCSA) initiated this project to understand the nature and prevalence of harassment and assaults against truckers. Harassment, in this study, is defined as the threat of harm or actual physical harm perpetrated against a trucker, their possessions, vehicle, or cargo. Harassment was evaluated for women and minority male truckers with incidence among non-minority males serving as a control. The project team first performed a literature review on the topic, which indicated that threats of harm and actual physical harm are the most common types of crime committed against women and minority truckers; however, they are experienced differently among the two groups. The literature review was followed by the development of an online survey to collect data. The data collected pertained to three driver groups: 1) women truck drivers, 2) minority male truck drivers, and 3) non-minority male truck drivers (control group). Next, a statistical analysis was performed to determine if the nature and frequency of crimes committed against women and minority male truck drivers differ significantly from the control group of non-minority male truck drivers. The survey data provided important insights into the nature and frequency of harassment against truck drivers, where and when these incidents occur, characteristics of the aggressors, how many of these incidents go unreported and why, and the harassment odds risk of women and minority truck drivers relative to non-minority truck drivers. The following are suggestions provided by surveyed truck drivers for preventing future harassment against truckers and include enhancing safety at existing trucking facilities, providing additional parking facilities, allowing firearm carrying in the trucking industry, improving communication within the trucking industry, providing personal safety training to truck drivers, and developing educational material to increase awareness. Note: regulatory and policy changes related to carrying firearms are beyond the purview of FMCSA\u2019s authority
Vehicle Classification and Equipment Type Crash Data and Market Survey
DTNH22-15-A-00050NHTSA evaluates market trends and crash data to understand how FMVSS affect motor vehicle safety. This report describes a crash data and market survey of five vehicle and equipment categories that all have unique relevance in the FMVSS: (1) large passenger vehicles, trucks, and SUVs excluded from FMVSS No. 208 air bag requirements (Class 2B); (2) limousines over 10,000 lbs. GVWR; (3) \u201centertainer\u201d buses and motor homes over 26,000 lbs. GVWR; (4) medium buses that carry 11 or more occupants; and (5) motorcycle helmets. A market survey was conducted for all five vehicle and equipment categories, while the crash data analysis was conducted only for Class 2B large passenger vehicles of GVWR 8,500 lbs. to 10,000 lbs
Assessment of Insourcing/Outsourcing Practices for Traffic Monitoring Data Collection
DTFH61-13-D-00012, Task Order No. 0006The State Departments of Transportation (DOTs), Metropolitan Planning Organizations (MPOs) and local transportation agencies have been conducting traffic monitoring activities in conjunction with the Federal Highway Administration\u2019s (FHWA) Traffic Monitoring Guide for over 30 years. Part of their role includes collecting quality data for a vast array of uses for their own internal programs, Federal uses and the general public. State DOT highway travel monitoring program personnel is continually challenged to maintain or expand their programs as well as implement advanced traffic monitoring technologies such as highway traffic monitoring data collection hardware and traffic statistics data management software. Over the years, numerous changes have occurred in the technologies available, improvement in quality of the traffic counting methods, the need for more efficient traffic counting programs and expanded scope of traffic data collection. Changes in how these traffic counting functions are performed have led some agencies to considering or moving toward contracting out various parts of their counting program (outsourcing) while others have continued to perform their activities using their own internal staff insourcing). This report presents the findings of the assessment of state DOTs, MPOs, and local transportation agencies\u2019 resourcing practices for all aspects associated with traffic data collection activities under three categories: 1) equipment installation, 2) permanent and portable counts, and 3) other/non-traditional contracting practices. The report shares the insight that was gained into the rationale behind agencies\u2019 decision-making processes by collecting data from approximately 80 agencies and conducting interviews with approximately 30 agencies throughout the U.S. The report summarizes the findings regarding agency practices for resourcing in several categories such as staffing, equipment, quality assurance/quality control, funding, and technology, along with some of the rationale behind the agencies\u2019 resourcing decisions, challenges the agencies have been facing, and methods they employed to overcome them. The report is intended to serve as a resource document to initiate dialogue between the state DOTs, MPOs, and local agencies to learn from each other\u2019s experiences. The report also provides a conceptual framework about the key considerations for developing decision-support mechanisms for the agencies to evaluate their current resourcing profiles
The metabolic syndrome is not associated with homocysteinemia: The Persian Gulf Healthy Heart Study
Background: It is uncertain whether homocysteine
and the metabolic syndrome or its components are related
in the general population, as studies investigating the
association between homocysteine levels and insulin resistance
have shown conflicting results. Methods: In an ancillary
study to the Persian Gulf Healthy Heart Study, a cohort
study of Iranian men and women aged ≥25 yr, a random sample
of 1754 subjects were evaluated for the association of
plasma homocysteine levels and the metabolic syndrome using
National Cholesterol Education Program (NCEP)-Adult
Treatment Panel (ATP)-III criteria. Total homocysteine levels
and high sensitivity C-reactive protein (CRP) were determined
by enzyme-linked immunosorbent assays. Results: Subjects
with lower HDL-cholesterol and higher blood pressure
showed significantly higher homocysteine levels (p=0.001
and p<0.0001; respectively). There was no significant difference
in serum levels of homocysteine between subjects with
and without the metabolic syndrome. In multiple logistic regression
analysis, the metabolic syndrome did not show a
significant association with serum homocysteine levels after
adjusting for sex, age, smoking, fruit and vegetable intake
pattern, body mass index, and physical inactivity. Concurrent
elevated CRP levels and the metabolic syndrome also did not
show a significant association with serum homocysteine levels
after adjusting for sex, age, and lifestyle cardiovascular
risk factors. Conclusions: There was no association between
the metabolic syndrome using NCEP-ATPIII criteria and homocysteinemia
in this study. These data refute the hypothesis
that homocysteine levels are influenced by the metabolic
syndrome, at least in general healthy population
Transit, Call Centers, and 511: A Guide for Decision Makers
Transit, Call Centers, and 511: A Guide for Decision Makers explores the operational characteristics of 511 telephone traveler information systems and examines how 511 systems interact with transit system call centers. This report inventories existing 511 systems throughout the country, documents the extent of transit participation and transit agency experiences with 511, and presents guidance to assist transit agencies and 511 system administrators in determining a transit-511 telephone strategy
