Abstract

fetched live from OpenAlex

The Advanced Traveller Information System (ATIS) is a web-based technology which provides the public critical information on incidents, detours, road closures general road conditions and travel times. ATIS helps motorists make informed decisions to improve their commute, reduce the environmental impact of driving and lessen driver frustration. As the primary source for traffic information in Calgary, ATIS makes it possible to communicate real-time information about Calgary's roadways through a variety of methods, including website updates, Smartphone access, subscription services, Dynamic Message Signs (DMS) and Traffic Advisory Radio updates. Additionally, static images from Calgary traffic cameras are fed to the ATIS website for viewing by the public. News media can distribute this information to the public via radio and television. Future access to traffic information is anticipated through Smartphone applications, additional websites and Global Positioning System (GPS) system providers by way of an open data feed. The City of Calgary's Roads Traffic Engineering division and corporate website development team, Webwave, worked together to implement a new traveller information system in preparation for the launch of a new Calgary.ca website. Starting work in early 2011, the intent of this project was to replace the existing Condition Acquisition and Reporting System (CARS) system with a modern ATIS system. Completed in November 2012, the ATIS proprietary software was created completely in-house by City of Calgary resources. In addition, a Bluetooth Travel Time Display system was developed to display actual travel times via DMS, and eventually, on the ATIS website.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
