street smart using vr simulation to combat traffic accidents

Street Smart aims to reduce pedestrian and cyclist deaths with an innovative VR campaign. A Chevrolet Camaro at the Springfield Town Center in Fairfax County on Sunday allowed visitors to test their skills as safe drivers. The mobile exhibit is part of the Metropolitan Washington Council of Governments' (COG) Street Smart campaign to improve pedestrian and bicycle safety. Kelvin Ford of Street Smart explains that the immersive VR experience interactively educates people of all ages about traffic safety. Participants put on a VR headset and virtually navigate local streets, keeping an eye out for pedestrians and cyclists. Many visitors who tried the simulation described it as entertaining, but also challenging.

One participant described the experience as “insanely fun” and “not easy.” Another noted that there were more blind spots than expected. The simulation was also designed to raise awareness of looking left and right at intersections. According to the COG, 115 pedestrians and cyclists were killed by vehicles in the Washington metropolitan area last year. Pedestrians and bicyclists account for more than 30 percent of all traffic fatalities in the region.

This study proposes a novel virtual-real-fusion simulation framework that integrates traffic accident generation, unmanned aerial vehicle (UAV)-based image collection, and a 3D traffic accident reconstruction pipeline with advanced computer vision techniques and unsupervised 3D... Specifically, a micro-traffic simulator and an autonomous driving simulator are co-simulated to generate high-fidelity traffic accidents. Subsequently, a deep learning-based reconstruction method, i.e., 3D Gaussian splatting (3D-GS), is utilized to construct 3D digitized traffic accident scenes from UAV-based image datasets collected in the traffic simulation environment. While visual rendering by 3D-GS struggles under adverse conditions like nighttime or rain, a clustering parameter stochastic optimization model and mixed-integer programming Bayesian optimization (MIPBO) algorithm are proposed to enhance the segmentation of large-scale... In the numerical experiments, 3D-GS produces high-quality, seamless, and real-time rendered traffic accident scenes achieve a structural similarity index measure of up to 0.90 across different towns. Furthermore, the proposed MIPDBO algorithm exhibits a remarkably fast convergence rate, requiring only 3–5 iterations to identify well-performing parameters and achieve a high \({R}^{2}\) value of 0.8 on a benchmark cluster problem.

Finally, the Gaussian Mixture Model assisted by MIPBO accurately separates various traffic elements in the accident scenes, demonstrating higher effectiveness compared to other classical clustering algorithms.

Traffic accidents often involve complex dynamics and multiple contributing factors, making accurate accident reconstruction crucial for understanding the chain of events leading to an accident [1,2,3]. Traditional accident investigation methods, such as witness statements and physical evidence analysis, provide limited insights. 3D reconstruction, on the other hand, allows investigators to recreate the accident scene in a virtual environment, offering a comprehensive and detailed representation of the event. However, the practical application of 3D traffic accident reconstruction has been limited in the real world due to its complexity and high labor costs [4, 5].

Fortunately, recent advancements in computer vision and machine learning have paved the way for more efficient and cost-effective methods of 3D reconstruction [6,7,8], facilitating its development towards automation and intelligence. Over the last ten years, geomatics technologies have been employed in 3D traffic accident reconstruction using tools and methods such as total station surveying, light detection and ranging (LiDAR) laser scanning, and photogrammetry. Total station surveying is a widely utilized technique for reconstructing traffic accidents [9], providing a comprehensive understanding of the event through precise measurements and 3D modeling. The working principle of total station surveying in traffic accident reconstruction involves the integration of electronic distance measurement (EDM) and automatic leveling capabilities. However, the equipment and software required for this method can be prohibitively expensive, posing a financial challenge for organizations with limited resources. Additionally, the operational process involved in total station surveying is intricate and demands skilled operators, thus adding to the complexity and potential for human error.

LiDAR-based 3D traffic accident reconstruction operates by employing laser scanning technology to capture high-precision point cloud data of the environment, vehicles, and debris [10]. This point cloud data is then processed and registered to create detailed 3D models of the accident scene. However, this approach suffers from inherent limitations, such as the prohibitively expensive of LiDAR systems, the lack of color and texture information in the resulting point cloud data, hindering accurate representation and analysis of... Photogrammetry-based 3D traffic accident reconstruction involves acquiring overlapping photographic imagery of the scene from multiple viewpoints and employing specialized software to extract three-dimensional geometric information and generate dense point clouds or textured mesh models... While this approach leverages cost-effective imaging sensors and captures valuable color and texture details, it is susceptible to errors arising from factors such as poor imaging geometry, obstructed or reflective surfaces, and suboptimal lighting... Overall, all three methods are explicit 3D modeling techniques that directly capture and represent the geometry of a scene as discrete points, meshes, or surfaces.

While these methods have proven effective in various applications, they have limitations such as difficulties in capturing intricate details, handling non-rigid scenes, and being sensitive to lighting conditions, and often require time-consuming and labor-intensive... Having seen the success of the Look Twice project in Texas, the Metropolitan Washington Council of Governments (MWCG) wanted to leverage a similar concept and put it to work for pedestrian and cyclist safety. Using the latest in interactive 360 video and VR, CM&D was able to help MWGC develop an engaging event activation that went on to touch thousands. Develop an event activation that engages with audiences young and old to help improve pedestrian and cyclist safety on roads in the Washington DC metropolitan area. Design and develop a multi-part 360 video powered VR application allowing users to experience the “TTec Difference” from anywhere in the world. Engaging with tens of thousands of event attendees and garnering hundreds of news stories, the final VR experience was so successful, MWCG renewed the project for an additional year.

Virtual reality has the power to transport people to another time and another place, creating a sense of presence in the viewer. MWCG was able to leverage this potential and engage with event attendees in a powerful and lasting way, by putting users in the driver’s seat and allowing them to practice their skills as an...
