New Model for Highway-Rail Grade Crossing Accident Prediction and Severity

Published in October 2020, The U.S. Department of Transportation Accident Prediction and Severity (APS) model has been used by Federal, State, and local authorities to assess accident risk at highway-rail grade crossings since the late 1980s. The Federal Railroad Administration funded research for the development of a new model that employs current consensus analysis methods and recent data trends. The new model also seeks to address several limitations of the current APS model and to provide a more robust tool for analysts. "New Model for Highway-Rail Grade Crossing Accident Prediction and Severity" presents the stages of the new model development, the statistical estimation of the new model, and validations comparing the performance of the new model with the APS. The research shows that the new model described here out-performs the APS by multiple measures.

The new model will support grade crossing management by enabling: more accurate risk ranking of grade crossings, more rational allocation of resources for public safety improvements at grade crossings, and the ability to assess the statistical significance of variances in the measured risk at grade crossings.

Export-Import Bank of the U.S. - Analysis of Structural Oversupply
Decisiontek examined the issue of structural oversupply in the global market for passenger airline services for the Export-Import Bank of the US. This market, and especially the long haul intercontinental segments of the market, relies on widebody aircraft produced by the US-based Boeing and the European Airbus. The general study approach was to characterize conditions of structural oversupply and its consequences (i.e., causes and effects), and to determine whether empirical evidence supported - or negated- a finding of structural oversupply in the global market for air services. 

NCHRP Report 775 Comprehensive Costs...

"NCHRP Report 755 Comprehensive Costs of Highway-Rail Grade Crossing Crashes" presents a process for estimating the costs of highway-rail grade crossing crashes. Departments of transportation (DOTs) and other public agencies use such estimates in making decisions about investments to install safety devices or reconstruction to provide grade separation of the road and rail line. The report will be helpful to officials of such agencies who must identify and assess the merits of investments proposed to enhance safety at grade crossings.

The report is the product of research led by Decisiontek in partnership with Economic Development Research Group, System Metrics Group and Susan Jones Moses & Associates.

Economic Model for Bureau of Ocean Energy Mangement
In 2014-2015 Decisiontek worked with the Bureau of Ocean Energy Management (BOEM) to update their IMODEL economic model software. IMODEL simulates a series of auctions for outer-continental shelf leases for energy resource development and production. Decisiontek's redesigned IMODEL and migrated it to a new platform to keep with pace with BOEM's evolving needs.
