Shahriar Beigi is a civil engineer and transportation AI researcher advancing safer mobility through infrastructure, machine learning, simulation, and connected vehicles.
Bridging physical infrastructure and intelligent mobility.
I am a University of Virginia Ph.D. candidate and civil engineer researching how autonomous and connected vehicles make decisions under uncertain traffic conditions.
My perspective is grounded in real infrastructure: federal highway safety, bridge and tunnel inspection, structural design, load rating, and field construction.
Professional focus
Engineering across two frontiers.
01
Autonomous & connected mobility
Decision-making, collision-risk evaluation, mixed-traffic control, adaptive cruise control, and infrastructure readiness for automated vehicles.
⌁02
Machine learning & simulation
Python and PyTorch models, time-series prediction, uncertainty calibration, VR studies, trajectory processing, and validation across observed and simulated data.
∿03
Civil & structural engineering
Highway safety, bridge and tunnel inspection, load rating, structural design, roadway audits, roadside barriers, and construction coordination.

Research Experience.
Four connected research programs spanning observed traffic data, virtual reality, autonomous-vehicle sensing, connected control, and field-test planning.
01Prediction + control
Traffic Data Analysis and Mixed-Traffic Safety Research
University of Virginia · Charlottesville, Virginia
Developed acceleration predictors and mixed-traffic control methods from 100+ observed car-following scenarios to study longitudinal decisions, rear-end crash risk, and string stability.
Screened and cleaned 100 NGSIM scenarios through data-quality checks, trajectory smoothing, and recalculation of acceleration before model development.
Designed separate training, validation, calibration, and test datasets to prevent temporal leakage; measured prediction error with RMSE, MAE, and R² and assessed uncertainty using interval coverage and width.
Evaluated control strategies for three-vehicle mixed-connectivity platoons using stability and crash-risk measures to assess connected-vehicle behavior.
02Human factors
Virtual Reality Safety Evaluation of Connected Cruise Control
University of Virginia · Charlottesville, Virginia
Conducted a 20-participant BeamNG/VR study, screened trial validity, and retained 17 participants for paired analysis of connected-cruise-control behavior.
Built traffic data records for speed, acceleration, headway, throttle, and braking; evaluated countermeasures using time exposed time-to-collision, deceleration rate to avoid crash, and rear-end crash risk index.
Documented data elements, safety-performance measures, methods, and findings in three technical reports for research sponsors.
03Systems review
Impact of Critical Situations on Autonomous Vehicles and Improvement Strategies
University of Virginia · Charlottesville, Virginia
Reviewed 50+ studies to characterize camera, LiDAR, radar, and GNSS sensing limitations under fog, glare, contamination, faded lane markings, and construction zones.
Assessed roadway-infrastructure needs for highway automation and published improvement strategies for lane markings, signs, maintenance, and work zones.
04Real-world validation
Connected-Vehicle Field-Test and Adaptive Cruise Control Planning
University of Virginia · Charlottesville, Virginia
Prepared a Comma.ai openpilot field-test plan for synchronized vehicle, GPS, and driver-monitoring data collection, staged validation, and driver-override criteria.
Proposed a risk-adaptive cruise-control strategy using time-to-collision, required deceleration, and stopping-distance margins; defined comparative tests for safety and control trade-offs.

Virginia
Promoted from Pathways Intern to full-time direct hire in Technical Services, supporting traffic operations and highway safety across a multiple-project portfolio.
Conducted roadway safety audits and guardrail warrant evaluations and prepared plans, specifications, and estimates for federal projects.
Analyzed National Park Service crash data for multiple park-road sites in ArcGIS Pro to support guardrail warrants and roadside safety-barrier decisions.
Applied MUTCD standards for signs, pavement markings, and signals across five federal projects to improve safety for all road-user groups.

Reviewed structural design plans for state-code compliance and tracked ground-improvement placement on the Spaulding Turnpike widening, including a new Route 4 prestressed-concrete beam bridge.
Field perspective
Infrastructure takes shape.
Engineering judgment is stronger when analysis stays connected to sequence, access, tolerance, and real construction conditions.
