Investigating Economic Viability of Personal Rapid Transit (PRT) System for a University Campus and Its Surroundings
Bibliographic record
Abstract
This paper discusses the methodology and results of an economic viability analysis of a demand-responsive personal rapid transit (PRT) system in a Canadian city. A microsimulation model was built to examine the feasibility of a PRT system linking the University of Calgary and surrounding major attractions. The environmental benefits of PRT operation were estimated in terms of reduction of air pollutants. Microsimulation was used to obtain accurate estimates of travel time and access/egress time for PRT and other transit modes, travel time savings for PRT patrons, and estimates of emissions. The investment costs were estimated using data from existing PRT projects (e.g., Heathrow Airport, Cardiff and Daventry, UK and Masdar City, Abu Dhabi, United Arab Emirates). Ridership was estimated by means of a catchment area method adopted from public transit. A cost-benefit analysis model was developed to evaluate the economic viability of the system, considering the capital and operation costs associated with serving the dispersed sites. The sensitivity of the internal rate of return to changes in demand and investment cost was also investigated.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot 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.
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 teacher head, not a consensus.
