This setup will combine virtual and physical worlds, with the car mounted on a steerable dynamometer providing all the dynamics associated with real driving, while the virtual world simulates synthetic sensor data corresponding to various situational context.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cIt is difficult to train machine learning for an unexpected combination of events that do not easily fall in a class that artificial intelligence can immediately recognize and classify,\u201d said Chakraborty. \u201cThis problem is further aggravated by the fact that millions of miles need to be driven in all sorts of conditions before having the chance to encounter relatively rare events. With VR, we can develop these difficult driving situations for CAVs to negotiate, such as recognizing a pedestrian in dark clothing crossing a dark street.\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Using VR will also provide a large quantity of realistic synthetic data that cannot be obtained otherwise. Khattak will provide statistical analysis of the data that can result in valid conclusions and influence policy making in the future.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The team will spend the next two years testing and collecting data. When the project is complete, the results will be used to provide safety certification standard recommendations that regulatory agencies at the state and federal levels and the private sectors can use.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Chakraborty looks forward to seeing this research impact the immediate future and one day being instrumental in preventing accidents.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Associate Professor Subhadeep Chakraborty and CEE Professor Asad Khattak are working together to standardize testing for autonomous vehicles. <\/p>\n","protected":false},"author":3,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"inline_featured_image":false,"footnotes":""},"categories":[384,7,6],"tags":[10],"class_list":["post-1191","post","type-post","status-publish","format-standard","hentry","category-faculty","category-news","category-research","tag-subhadeep-chakraborty"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.5 -
