DEMONSTRATION OF INTEROPERABLE ROAD-USER END-TO-END CHARGING AND TELEMATICS SYSTEMS (DIRECTS) FOR THE UK GOVERNMENT
Bibliographic record
Abstract
The Fareway Alliance, comprising KBR (Kellogg Brown & Root), Atkins Transport Systems, and Thales Telecommunications Services (TTSL) in the UK, was awarded the DIRECTS (Demonstration of Interoperable Road User Charging and Telematics Systems) contract by the Department for Transport (DfT), in March 2001. This challenging program requires Fareway to perform three principal tasks: (1) to develop, over the period of the contract, a suite of specifications for Road User Charging (RUC), providing interoperability between the various sub-system components; (2) to design, develop, test, install operate and decommission a complete end-to-end trial system for RUC at a number of urban and motorway locations in the South Eastern quadrant of the City of Leeds; and (3) to prove via the trial, the interoperability of systems provided by multiple suppliers. The program will include the recruitment of volunteers and over 500 vehicles will be fitted with On-Board Equipment (OBE). Over the course of a minimum of 12 months, the volunteers will receive monthly sample invoices and, where applicable, sample Penalty Charge Notices as part of the live demonstration of the system. The equipment suppliers to the trial include OBE, Road Side Equipment (RSE) and back-office systems suppliers from the UK, France, Austria, Germany, Sweden and Canada. In demonstrating this system on live roads, the Alliance and it's suppliers will be demonstrating it's ability to meet the Requirements specification Suite it has prepared on DfT's behalf, interoperability between systems and equipment, and sustained live operations over the trial period.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
