    WSDOT's commitment to highway safety. WSDOT is reducing traffic congestion, preserving transportation infrastructure and making safer roadways. Safety takes effort and vigilance. Our efforts are working. Washington continues to see a decline in the number of deaths due to traffic collisions. Our traffic fatality rates are among the lowest in the nation, but we have a long way. SEMS is a safety management system(SMS) aimed at shifting from a completely prescriptive regulatory approach to one that is proactive, risk based, and goal oriented in an attempt to improve safety and reduce the likelihood that events similar to the April Macondo incident will reoccur.

The purpose of this report is to review past Safety Board concerns regarding the adequacy of bridge and highway rail systems and to evaluate the FHWA's efforts to develop safer traffic barriers.

This study analyzes the results of recent crash-testing sponsored by the FHWA and makes recommendations concerning performance standards for traffic barriers. Podcast Lighting the Way to Safety: Warning Lights and Illumination for Vehicles, Traffic Control Devices, and the Work Area.

Dousing a Burn: Evidence Shows Steady Warning Light Is Ineffective (Publication) Work zone channelization devices provide invaluable information to motorists on. The study recommended that the Manual on Uniform Traffic Control Devices make note of the effect of opposing traffic headlight glare on delineators’ effectiveness, that delineators be placed on the top of concrete barriers, that prism-lensed devices are the most effective, and that delineators should be cleaned regularly.

Review and Survey Results of Innovative Traffic Control Devices The usage and the effectiveness of portable devices/systems that possibly could be used at short-term work zones were investigated. The survey focused on innovative or unique safety devices that any state is using or has used in the past and their states’ comments on the devices’.

The target audience includes data analysts and project managers involved in projects that impact highway safety. Barriers are not created equal. Some are better than others. Barrier effectiveness is a way to assess how well a barrier performs.

Effectiveness is often used as a single property of a Barrier. However, in this article we’ll break effectiveness down into two main elements. Adequacy and reliability. Evaluation of Intelligent Transport System in Road Safety.

While the regulatory specification of safety management systems implies a strong theoretical foundation, the historic evolution of safety management systems tells a rather different story.

The history of SMS is in many respects ‘organic’, having evolved from a haphazard collection of ‘best practice’ activities to promote safety. This literature review of traffic education programmes addresses the current. practice in evaluation research, the effectiveness of programmes and their.

The findings from the descriptive statistics, paired t-test and EB evaluation were very similar which reinforces the positive safety effectiveness performances of the cable barriers in Tennessee. The study found that the statewide cable barriers Safety Effectiveness (statistical percentage change in crash frequency across all statewide cable barrier segments) for fatal crashes is 94%, incapacitating Cited by: 7.

TRB Special Report Evaluating the Effectiveness of Offshore Safety and Environmental Management Systems recommends that the Bureau of Safety and Environmental Enforcement (BSEE) take a holistic approach to evaluating the effectiveness offshore oil and gas industry operators' Safety and Environmental Management Systems (SEMS) programs.

WHO and partners: Data systems: a road safety manual for decision-makers and practitioners. MONITORING AND EVALUATION As countries make road safety a priority and adopt. Roadside safety is one of the important components of highway systems due to its considerable rate of high-severity crashes.

Traffic barriers play a key role in reducing the crash severity and. The aim of this thesis was to investigate how two vehicle safety systems, electronic stability control (ESC) and intelligent seat belt reminders (SBR), could deliver improved road traffic safety.

Further the Plan-Do-Check-Act approach was investigated as a systematic mean for the evaluation of effects of new safety technologies. Barrier #4: Attitude. The attitude of an organization, from all employees, affects the success of a safety program.

A lack of trust, or leaders who focus on the past, can frame any change as a negative, so it’s important to work together.

Ask leadership to be vocal supporters of your safety program. Overall, the evaluation results show that the median cable barriers installed in Ohio's Interstate system are effective in reducing cross-median severe injury crashes, which was the main objective of ODOT's installing median barriers in their Interstate highway system.

Barriers can be manually or automatically controlled and, of course, we can integrate with CCTV, access control and even automated recognition systems.

Under an experimental features study requested by the Federal Highway Administration, the Indiana Department of Transportation installed a proprietary cable median barrier system, i.e., the Brifen four-rope wire rope safety fence (WRSF), to assess issues in installation, maintenance, and repair of this WRSF system and to evaluate its in-service performance.

Accordingly, safety barriers should either be terminated with a crashworthy terminal treatment that complies with the appropriate test level requirements of NCHRPor the safety barrier should be extended outside the clear zone at the File Size: KB.

A cable barrier, sometimes referred to as guard cable or wire rope safety barrier (WRSB), is a type of roadside or median safety traffic barrier / guard rail.

It consists of steel wire ropes mounted on weak posts. As is the case with any roadside barrier, its primary purpose is to prevent a vehicle from leaving. On the other hand, the concrete C barrier successfully contains and redirects kg bus impact, with minimal barrier deformation and safety risk.

Even though the concrete barrier slides toward the inside of the ditch, the bus does not enter the ditch area and exits the barrier in a stable manner.
