“…As previously mentioned, one of the key features of the DeepStream model is its powerful platform for simultaneously analyzing multi‐stream videos with low latency. In fact, it has been shown that DeepStream can simultaneously manage the processing and analysis of data from up to 160 traffic surveillance cameras in real‐time on just two NVIDIA T4 GPUs (Huang & Sharma, 2020). Our WWD detection model experiments showed that DeepStream achieved an inference speed of 1162 frames per second.…”

Hundreds of fatal accidents occur each year due to wrong-way driving (WWD). Although several methods have been developed to detect WWD using existing closed-circuit television (CCTV) data, they all require manual recalibration whenever a camera rotates, and are thus not scalable across statewide CCTV networks. This paper, therefore, proposes an end-to-end deep-learning-based model that considers camera orientation as a variable, detecting camera rotation automatically and learning new decision criteria accordingly using a neural network model. We show that our proposed solution can detect WWD with a precision of 0.99 and a recall of 0.97. Due to its cheap computational cost and high error tolerance, our solution is easily scalable for statewide surveillance on a real-time basis to help decision-makers reduce fatalities due to WWD. INTRODUCTIONBased on the National Highway Traffic Safety Administration's Fatality Analysis Reporting System, the annual average of 269 fatal crashes from 2004 through 2011 due to wrong-way driving (WWD) resulted in more than 350 people dying each year (Pour-Rouholamin et al., 2015).According to federal and state crash data, 20% to 25% of crashes from WWD are fatal. This percentage is significant, compared to the 0.5% fatality rate, for vehicle crashes overall (MH Corbin, 2020).Several studies (such as Baratian-Ghorghi et al., 2014;Leduc, 2008;Zhou et al., 2012) have investigated different factors in WWD accidents and have shown that in 58% of the crashes, drivers were under the influence of alcohol.To prevent drivers from entering the wrong side of the road, several passive mechanisms have been implemented, such as wrong-way signs or raised pavement markers on roads (Baratian-Ghorghi & Zhou, 2017;Cooner et al., 2003) and in-pavement warning lights. In parallel with deploying passive mechanisms to minimize WWD incidents, many
