Motor vehicle crashes remain a leading cause of life and property loss to society. Autonomous vehicles can mitigate the losses by making appropriate emergency decision, and the crash injury severity prediction model is the basis for autonomous vehicles to make decisions in emergency situations. In this paper, based on the support vector machine (SVM) model and NASS/GES crash data, three SVM crash injury severity prediction models (B-SVM, T-SVM, and BT-SVM) corresponding to braking, turning, and braking + turning respectively are established. The vehicle relative speed (REL_SPEED) and the gross vehicle weight rating (GVWR) are introduced into the impact indicators of the prediction models. Secondly, the ordered logit (OL) and back propagation neural network (BPNN) models are established to validate the accuracy of the SVM models. The results show that the SVM models have the best performance than the other two. Next, the impact of REL_SPEED and GVWR on injury severity is analyzed quantitatively by the sensitivity analysis, the results demonstrate that the increase of REL_SPEED and GVWR will make vehicle crash more serious. Finally, the same crash samples under normal road and environmental conditions are input into B-SVM, T-SVM, and BT-SVM respectively, the output results are compared and analyzed. The results show that with other conditions being the same, as the REL_SPEED increased from the low (0–20 mph) to middle (20–45 mph) and then to the high range (45–75 mph), the best emergency decision with the minimum crash injury severity will gradually transition from braking to turning and then to braking + turning.

AbstractObjectivesTo determine if changes to the Ontario Highway Traffic Act (OHTA) in 2009 and 2010 had an effect on the proportion of alcohol-related motor vehicle collisions (MVCs) presenting to a trauma centre over a 10-year period.MethodsA retrospective review of the trauma registry at a Level I trauma centre in southwestern Ontario was undertaken. The trauma registry is a database of all trauma patients with an injury severity score (ISS) ≥12 and/or who had trauma team activation. Descriptive statistics were calculated. Interrupted time series analyses with ARIMA modeling were performed on quarterly data from 2004-2013.ResultsA total of 377 drivers with a detectable serum ethanol concentration (SEC) were treated at our trauma centre over the 10-year period, representing 21% of all MVCs. The majority (330; 88%) were male. The median age was 31 years, median SEC was 35.3 mmol/L, and median ISS was 21. A total of 29 (7.7%) drinking drivers died from their injuries after arriving to hospital. There was no change in the proportion of drinking drivers after the 2009 amendment, but there was a significant decline in the average SEC of drinking drivers after changes to the law. There was no difference in the proportion of drinking drivers ≤21 years after introduction of the 2010 amendment for young and novice drivers.ConclusionsThere was a significance decline in the average SEC of all drinking drivers after the 2009 OHTA amendment, suggesting that legislative amendments may have an impact on drinking before driving behaviour.

ABSTRACT Background: Alcohol is a frequent contributing factor to motor vehicle collision injuries. Our objective was to determine the proportion of intoxicated drivers hospitalized following motor vehicle crashes who were subsequently convicted of an impaired driving criminal code offence. Methods: We reviewed British Columbia Trauma Registry records from Jan. 1, 1992, to Mar. 31, 2000, and identified drivers of motor vehicles who were hospitalized for treatment of crash-related injuries. Patient identifiers were then used to link with the Insurance Corporation of British Columbia’s (ICBC) contraventions database and the ICBC Traffic Accident System collisions database. Results: Of 6067 patients identified in the Trauma Registry, 4042 had not been administered a blood ethanol test, 209 had no driver’s licence match in the relevant databases and 119 died, leaving 1697 eligible patients. Mean age was 34 years, and 79.6% were male. The average Injury Severity Score was 20, the average hospital stay was 14 days and, among ethanol-positive patients, the mean ethanol level was 34.0 mmol/L (156.4 mg/dL). In patients with levels >17.3 mmol/L, the police had listed ethanol as a contributing factor in 70.6% of cases. Despite this, only 11.0% were convicted of impaired driving and 8.4% of another criminal offence; 10.7% received a 24-hour roadside prohibition, 3.9% received a 90-day administrative driving prohibition and 25.0% were convicted of a contravention of the Motor Vehicle Act. Forty-one percent were not convicted of any offence at all. Conclusions: Intoxicated drivers in British Columbia requiring hospitalization as a result of alcohol-related motor vehicle crashes are seldom convicted of impaired driving or other criminal code offences.
