The field data were used to demonstrate how on-site instrumented vehicle data can be used to validate simulated vehicle dynamics using the validation framework. \n\nThe vehicle trajectory data were collected in a separate task of the Active Transportation Demand Management (ATDM) Trajectory Level Validation project. The primary project objective was to develop a methodology to validate simulated vehicle dynamics at the trajectory level. Microscopic and macroscopic performance measures were calculated from the trajectory data and used in a number of validation tests related to safety, vehicle limits, driver comfort levels, and traffic flow", "distribution": [{"@type": "dcat:Distribution", "downloadURL": "https://data.transportation.gov/download/25r8-p3cy/application/msword", "mediaType": "application/msword"}], "identifier": "https://data.transportation.gov/api/views/25r8-p3cy", "issued": "2017-12-31", "keyword": ["active transportation demand management (atdm)", "arterial", "california", "category: vehicle safety", "connected equipment", "emeryville", "freeway", "global positioning system (gps)", "intelligent transportation systems (its)", "its joint program office (jpo)", "on-board diagnostics (obd)", "radar", "real time kinematic (rtk) gps", "san francisco", "san francisco bay area", "shapefiles", "simulated data", "subcategory: autonomous vehicle safety systems", "traffic flow", "trajectories", "vehicle data"], "landingPage": "https://data.transportation.gov/d/25r8-p3cy", "language": ["en-US"], "license": "http://creativecommons.org/licenses/by-sa/3.0/legalcode", "modified": "2017-12-31", "programCode": ["021:013"], "publisher": {"@type": "org:Organization", "name": "US Department of Transportation"}, "spatial": "San Francisco, California", "temporal": "2016-04-11/2016-05-16", "theme": ["Automobiles"], "title": "Active Transportation Demand Management (ATDM) Trajectory Level Validation"}
