Despite large investments in traffic safety programs and technologies, motor vehicle accidents continue to impose high social costs, and crash casualty rates have recently started to increase. New strategies are needed to achieve ambitious traffic safety targets such as Vision Zero. Recent research improves our understanding of factors that affect traffic risks and identifies new […]
The assailant slipped out of a park around noon one day in October, zeroing in on his target, which was idling at a nearby intersection — a self-driving van operated by Waymo, the driverless-car company spun out of Google. He carried out his attack with an unidentified sharp object, swiftly slashing one of the tires. […]

Summary of Recommendations Speed Reduction Increase in patrol officers both at the ALEA and local levels Comprehensive demonstration speed reduction projects Legislative action to recognize problem and increase funding to ALEA specifically for field officers Continue hot-spot selective enforcement targeting and assure compliance to it Roadway improvements: trees, rollovers, utility poles, ditches, embankments Seat-belt (Restraint) […]
This document reports the results of a study to determine on average over a large number of cases, which driver is more apt to be at fault in two-vehicle crashes that involve two types of drivers (e.g., large truck and car; car and pedestrian, car and bicycle, car and motorcycle, etc.). This information is essential […]
This document presents the results of a comparison of ID crashes compared to non-ID crashes over a recent three year period (FY2015-2017). An over-represented value of an attribute is a situation found where that attribute has a greater share of ID crashes than would be expected if it were the same as that same attribute […]
The high level analysis of vehicles in general for vehicle defects showed a high correlation of the defect type and the vehicle type, which is expected since certain defects apply only to trucks. The Causal Unit analysis given immediately below establishes that: (1) the most over-represented vehicles are heavy trucks (as we might expect), but […]
This section will attempt to stay away from the typical traditional safety recommendations in order to concentrate on those discovered from the research that is summarized in the next section. This does not mean that the safety practices typically taught as standard large truck training are not important. They are important and should be given […]
The goal of this problem identification is to assure that the restraint enforcement program considered by the state throughout 2019 is completely evidence-based, the evidence being derived from past data obtained from crash records. Changes from what appeared in the previous year HSP will only be noted in cases where they are considered to be […]
Most Counter-Intuitive Findings Weather Conditions and Speed Lowest % speed related fatalities occur in rain Speed increases wet pavement crash % by a factor of 3.5 Impaired Driving and Speed DUI alcohol use increases 69% for speed crashes Reported drug use increases 44% for speed crashes Age and Speed Highest frequency ages, in order: 18, […]
