Abstract
Service Level Evaluation of Florida's Highways Considering the Impact of Autonomous Vehicles Amirsaman Mahdavian, Alireza Shojaei and Amr Oloufa Pages 1163-1170 (2019 Proceedings of the 36th ISARC, Banff, Canada, ISBN 978-952-69524-0-6, ISSN 2413-5844) Abstract: Automated vehicles (AV) are undergoing development at a remarkable pace and have the potential to revolutionize the existing transportation system. The ASCE [1] evaluated the United States' infrastructure as a D+ grade. Moreover, they predicted radical infrastructure investment gaps in the surface transportation sector in the upcoming years. Some new urbanized regions might require new highways. Meanwhile, many other highways are reaching the end of their service life and will need significant repairs or even replacement. However, this seems to be unrealistic to happen until having a high market penetration of Fully Connected and Autonomous vehicles on the road to benefit from the capacity expansion benefits. Regarding the funding related issues of highway construction in the U.S. and the emergence of AVs, having a better understanding of the future's traffic status is a must. This study investigates the impact of autonomous vehicles on Florida's district five of I-95 highway traffic including three counties: Flagler, Volusia, and Brevard. This research is the first study to develop a fusion model considering the impact of both traffic flow and capacity adjustments based on the literature review to forecast the traffic from 2020 to 2040 by considering the increasing AV market penetration. The proposed approach provides a more realistic plan for government agencies and private investors, and as a result, significant savings financially and resource-wise can be achieved. The findings of the study confirm that autonomous vehicles will increase traffic flow and capacity, and the increase in flow is higher than the increase in capacity.

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 it
