As a key indicator of unsafe driving, driving volatility characterizes the variations in microscopic driving decisions. This study characterizes volatility in longitudinal and lateral driving decisions and examines the links between driving volatility in time to collision and crash injury severity. By using a unique real-world naturalistic driving database from the 2nd Strategic Highway Research Program (SHRP), a test set of 671 crash events featuring around 0.2 million temporal samples of real… Expand

Built environment, driving errors and violations, and crashes in naturalistic driving environment.
While the most prevalent errors in crashes were recognition errors such as failing to recognize a situation and decision errorssuch as not braking to avoid a hazard, performance errors were most strongly correlated with crash occurrence. Expand
Safety critical event prediction through unified analysis of driver and vehicle volatilities: Application of deep learning methods.
This study aims to predict occurrence of safety critical events and generate appropriate feedback to drivers and surrounding vehicles by integrating and fusing multiple real-time streams of data, i.e., driver distraction, vehicular movements and kinematics, and instability in driving. Expand
Injury severity analysis of pedestrian and bicyclist trespassing crashes at non-crossings: A hybrid predictive text analytics and heterogeneity-based statistical modeling approach.
A two-staged hybrid approach is proposed where text mining is applied first to extract valuable information from crash narratives followed by inclusion of the new variables derived from text mining in formulation of advanced statistical models for injury outcomes. Expand
Real Time Safety Model for Pedestrian Red-Light Running at Signalized Intersections in China
Development of real-time safety models for pedestrian red-light running using the signal cycle level traffic data in Nanjing, China shows that pedestrian volume, ratio of males, ratios of pedestrians on phone talking, pedestrian waiting time, green ratio, signal type, and length of crosswalk are statistically significantly associated with the pedestrians’ red- light running.

Treating two pandemics for the price of one: Chronic and infectious disease impacts of the built and natural environment
It is suggested that creating walkable environments with greenspace is associated with reduced risk of chronic disease and/or COVID-19 infection and mortality and the relationships between CO VID-19 mortality, obesity, and key correlates exhibit significant heterogeneity. Expand
Developing policy thresholds for objectively measured environmental features to support active travel
A novel evidence-based methodology is presented for determining place-based thresholds of objectively measured built environment features’ relationships with active travel, revealing strong and complex non-linear dependencies of likelihood of transport walking on environmental features that cannot be quantified using standard threshold detection methods.

Examining the influence of aggressive driving behavior on driver injury severity in traffic crashes.
The moderating effect of aggressive driving behavior is captured while assessing the influence of a comprehensive set of variables on injury severity, and the safest situation from a driver injury standpoint is when there are two or more passengers in the vehicle. Expand
Analysis of volatility in driving regimes extracted from basic safety messages transmitted between connected vehicles

Examining driver injury severity in two vehicle crashes - a copula based approach.
A copula based joint framework is proposed to study collision type and injury severity sustained as two dimensions of the severity process and incorporates collision type as a vehicle-level, as opposed to a crash-level variable as hitherto assumed. Expand
