Roadside safety

Roadside safety performance will be closely monitored to ensure basic safety management controls are operating effectively. 

Analysis of roadside safety barrier using numerieal model... 

The concrete model was primarily developed to simulate the deformation and failure of concrete in roadside safety structures impacted by vehicles. Examples are bridge rails and safety barriers.

Once a complete set of robust parameters had been determined, the data matrix was divided into tabs, identifying those parameters related to the decisions for each VRS type, i.e. roadside safety barriers, median safety barriers, bridge parapets, crash cushions, transitions, terminals and motorcyclist protection systems (MPS). Due to the low level of published guidance for terminals, transitions and MPS, these were removed from the data matrix. For each parameter, it was then determined whether it applied to the decision to install a VRS or to the selection of the performance for the VRS.

The most frequent safety improvements are those related to the roadside, including increasing the clear zone and upgrading barriers and other roadside safety devices.

MD No Roadside Safety Audits, Safety Analysis and Cost/Benefit Analysis are performed to help develop scope of a project. However, traditional system preservation projects (areawide resurfacing projects) do not go through such analysis. 

MO Yes Missouri has a fledgling RSA process and not all 3R projects are analyzed today. A great deal of analysis goes into the design of roadside safety because of the severity of roadway departure crashes and because upgrades are cost-effective within the 3R environment. 

NV Yes Department conducts road safety audits on all 3R projects on the Interstate. If time and resources permit, other 3R projects also have road safety audits. In addition to the road safety audits, the Department does a roadside safety review foeusing on clear zone issues and standards compliance. 

MI Intersection improvements Lane width with crush and shape work Superelevation/cross slope Paved shoulder width Roadside safety... 

MI Bridges are fixed, more costly, longer service life, and less flexible in alternative repairs than road facilities. Roadside safety... 

SC These three are directly related to the safety and operations of the facility. Roadside safety and clear zone, available right-of-way, environmental impacts, intersection sight distance, pedestrians, ADA accessibility, bicyclists... 

NH Need to be flexible with design standards when you can t meet the minimums due to type of work. Scope of work does not permit addressing all controlling design elements, and requires solid engineering judgment to develop cost-effective solutions to maximize highway and roadside safety.
