MCS-150 updates show up faster on SAFER and the FMCSA Portal websites. You can find the schedule of SMS updates at. PLEASE NOTE: The SMS website is updated monthly, so your MCS-150 changes will not be reflected on that site until the next monthly update. Under the “Existing Registration Updates” section, choose the first option – “I need to update my USDOT number registration information or file my biennial update.” Visit to update your MCS-150 information. Update your MCS-150 now with 2011 VMT/PU information or shortly after Januwith your 2012 data to ensure that FMCSA is using the most accurate data available to calculate your percentiles. View the SMS Methodology for addition details on BASIC percentile calculations. Instead, the level of exposure will default to average PUs over the previous 18 months which can impact your percentiles in the Unsafe Driving and Crash Indicator BASICs. If your VMT data in FMCSA’s database is from 2010 or older, it will not be used in your calculations when the January SMS snapshot is posted at the beginning of February. (Photo credit: Wikipedia)ĭid You Know…As a motor carrier, recent Vehicle Miles Travelled (VMT) and Power Unit (PU) data from your Motor Carrier Registration form, known as the MCS-150, are required and must be up to date to properly assess your level of exposure in the Unsafe Driving and Crash Indicator Behavior Analysis and Safety Improvement Categories (BASICs) in FMCSA’s Safety Measurement System (SMS). The presented methodology may allow agencies to better justify safety improvements on local roads that have experienced limited crashes but for which the potential consequences are severe if crashes occur.English: Logo of the United States Federal Motor Carrier Safety Administration. The potential crash cost savings afforded by these improvements were found and utilized in a benefit-cost analysis to assess the feasibility. Appropriate low-cost safety improvements were proposed with the aim of reducing the crash risk as determined from the findings of the statistical analysis. Moreover, this research describes a framework that shifts the focus of benefit-cost analysis from expensive safety improvements applied at individual locations to programs of low-cost improvements applied uniformly over many locations. Conversely, three-leg intersections have a decreased risk of both crash types. The results suggest that increases in AADT on the major and minor roads, driveways/access points located on the major road near the intersection, and trees/brush obstructing the sightlines in the intersection corners increase the risk of FI and PDO crashes at rural local intersections. The model is applied in the context of Indiana local intersections to identify the road/roadside features influencing the risk of the fatal/injury (FI) and property damage only (PDO) crash types. The collected road/roadside features, AADT, and crashes are used in estimating the bivariate ordered probit model, a statistical model that is well suited to handling the lower crash counts often present on rural local roads. Such data may be lacking or incomplete in existing local repositories. A practical approach for obtaining geometry, roadway infrastructure, and roadside features is presented. This dissertation describes a method for assessing the risk of crashes on rural local roads. There is a considerable risk of severe crashes at multiple locations, but it is not revealed with a high crash frequency at particular locations. The identification and mitigation of safety problems at high-crash locations with costly improvements, as is typically the case with rural state roads, is not suitable for rural local roads since safety problems are less apparent. Rural local roads are often maintained by counties and townships, have low-volumes, and may have obstructed sightlines, outdated geometrical designs, and roadside obstacles that make them dangerous to roadway users. Rural local roads have lower crash frequencies than rural state roads, but greater crash rates (when adjusted for VMT). However, more than 80% of rural roads in Indiana and other heavily agricultural states are local roads. You self-report how many miles your company drove in the last year, but VMT has nothing to do with your authority being inactive. For higher-volume rural state roads with a considerable crash history, the effect of road geometry, infrastructure, traffic, and roadside features on crashes has been studied extensively. traffic fatalities (in excess of 15,000) occur in rural areas. population and have 30% of the annual vehicle miles traveled (VMT), more than half of the annual U.S. Project-Oriented Safety Management of Rural Local RoadsĪlthough rural areas make up 19% of the U.S.
