19. Training STAC working with FHWA’s National Highway Institute (NHI ) and NDS and RID support contractors to develop training Two general types of training will be developed: I.High level for decision makers II.Detailed, hands-on suitable for analysts Detailed training will begin with pilot sessions Two with USDOT staff and onsite contractors (1 st April 2016) Two with state DOTs and research partners These pilots will help us refine the material that NHI will turn into ‘official’ instructional training 19

20. Stages of remote access Stage 1: Testing with non-PII data - approved at March 2015 SDOC meeting (now till Spring 2016) Stage 2: Testing with PII – after successful demonstration of Stage 1 Stage 3: Secure remote access to PII- will seek SDOC approval following successful demonstration of Stage 2 20

21. Tools and reduced data sets Exploratory Advanced Research (EAR) video analytics projects to enhance usability of NDS data (semi-automate processes): Identity masking Driver behavior Signal state GIS dynamic segmentation tool – for non-GIS savvy users Reduced data sets (NDS and RID) – to support pilot studies 21
