Hi, I'm Atasi Roy Malakar.

A graduate traffic-control project using PTV VISSIM, HCS, and Excel to evaluate 2035 traffic growth and improvement strategies along John Nolen Drive in Madison. I led the analysis and quality control, comparing no-build, signal-optimized, and geometry-refined scenarios. Results showed 2035 growth could increase delay by 60–85% and queues by 3×, while signal and geometry improvements provided targeted but capacity-limited benefits.

A VISSIM-based advanced traffic modeling project evaluating how Connected and Automated Vehicles may improve traffic performance under normal, fog, and rain conditions along Madison's Beltline corridor. The study compared human-driven vehicles and CAVs using weather-based speed reductions, Wiedemann 99 car-following parameters, lane-changing behavior, and performance metrics such as delay, stops, stop delay, and speed.

A graduate highway-design project developing a conceptual 4.75-mile North Mendota Parkway corridor in Dane County. The work evaluated alternative alignments, farmland/hydrologic/terrain constraints, vertical and horizontal geometry, AASHTO Green Book design standards, traffic forecasting, and six intersection concepts to support a rural principal arterial design.

A graduate urban transportation planning project reviewing transit fare policy through equity, affordability, and financial-sustainability lenses. The study examined how fare structures can burden low-income, zero-car, and suburban riders, and evaluated tools such as fare capping, means-based discounts, fare-free pilots, and account-based fare systems using Madison as a local application case.

A MATLAB simulation project evaluating how Connected and Automated Vehicles could improve operations at stop-controlled intersections. I developed a simulation framework comparing HDV and CAV parameters, added a safety-check conflict-resolution algorithm, and tested performance through a detailed single-run case and 50,000 randomized multi-run trials across varying intersection complexity.

An independent study report synthesizing Advanced Air Mobility developments across aircraft typologies, certification frameworks, vertiport infrastructure, FAA/NASA initiatives, market readiness, and governance challenges. The project reviewed eVTOL, eSTOL, lift-plus-cruise, and hybrid fly-drive systems to assess how AAM may evolve from demonstration flights toward scalable mobility services.

Professional railway infrastructure work involving AutoCAD drawings, design validation, estimation support, and Excel/VBA automation. Built and reviewed workflows for girder bridge side pathways, RCC box subway checks, influence-line processing, DPR generation, double-line progress verification, and box-pushing subway drawing preparation. Area of experience: AutoCAD · VBA · RCC Box Subway Checks · Soil Safe-Bearing-Capacity Review · BBS/Reinforcement Check · Influence-Line Processing · DPR Automation · Box-Pushing Subway Method

Construction-engineering work for multipurpose cyclone shelter projects under World Bank Project ID P144726. Work included revised AutoCAD site plans, geotechnical and environmental coordination, site inspections, material testing support, Measurement Book / billing documentation exposure, and WBS-Gantt chart planning for 110+ construction sites.
