1. Highway Infrastructure: Federal -State Partnership Produces Benefits and Poses Oversight Risks - This report examines (1) how the federal-aid highway program and FHWA’s oversight have changed over time; (2) the extent to which FHWA’s partnership approach produces benefits; (3) the extent to which FHWA’s partnership approach poses risks; and (4) how FHWA’s partnership with state DOTs could affect a transition toward a performance-based highway program.
2. 2012 National Traffic Signal Report Card - This report discusses the findings in the context of the evolution of practices observed between the 2005, 2007, and 2011 self assessments and a generalized traffic signal program management plan. In addition, this report discusses opportunities and resources available to agencies as well as the future direction of traffic signal systems management and operations.
3. Motorcyclist Traffic Fatalities by State: 2011 Preliminary Data - The preliminary data shows motorcyclist fatalities decreased by 1.7% during the first nine months of 2011. However, experience in 2010 suggests that the final data are unlikely to show a decrease. Through nine months, fatalities decreased in 23 states and increased in 26 states and the District of Columbia, with fatalities unchanged in one state.
4. How Would Proposed Fuel Economy Standards Affect the Highway Trust Fund? - This report estimates the impact of the proposed CAFE standards on the nation's Highway Trust Fund over a 30 year period. It lays out several options for policymakers to consider to minimize the impact.
5. Measuring Corporate Attitudes to Employee Distracted Driving – 2012 Edition (Registration needed) - This report describes the modeling, calibration, and validation of a VISSIM traffic-flow simulation of the San José, California, downtown network and examines various evacuation scenarios and first-responder routings to assess strategies that would be effective in the event of a no-notice disaster.
6. Miscellaneous Reports
   • Mapping Large Truck Rollovers 2012 Report (Available upon request)- This report identifies dense concentrations of large truck rollovers using historical crash data from 2001 to 2009. This analysis demonstrates that a geographic database of large truck rollover events can be created to identify locations where large truck rollovers frequently occur.
   • Proactive Assessment of Accident Risk to Improve Safety on a System of Freeways - This report describes the development and evaluation of real-time crash risk-assessment models for four freeway corridors. The models are based on a binary classification approach, with traffic parameters measured at surrounding vehicle detection station locations as the independent variables. The analysis techniques used in this study are logistic regression and classification trees.
   • Cost Estimate Modeling of Transportation Management Plans for Highway Projects - This project develops a systematic cost estimation modeling process for Transportation Management Plans in order to assist Caltrans’ TMP engineers and project design engineers by automatically estimating TMP costs for highway projects using pre-established TMP elements grouped by TMP strategies.
