Phase 1 · Hello
Hi, I'm Tanvir.
Transportation engineer: signals, safety and the data in between. I'm an M.S. student at Western Michigan University in Kalamazoo.
Phase 2 · Dhaka → Kalamazoo
12,664 km
From Dhaka's waterways to Michigan's work zones.
- B.Sc. Civil Engineering (Transportation)BUET, Dhaka · 2023
- M.S. Civil Engineering (Transportation)Western Michigan University · 2025 – Present · GPA 3.88
Phase 3 · Waterbus · thesis + ICCESD 2024
Why Dhaka's first waterbus stopped after 18 months
16 km in ~90 min
- 35 seats per boatTwo boats could not meet demand
- Unreliable and infrequentBreakdowns, scattered schedules, little awareness
- Shut down within 18 monthsLaunched 28 August 2010 by BIWTC
16 km in ~24 min
- Hybrid electric water taxi, 50 seatsFaster and lighter on fuel
- 20 vessels on the 110 km circular routeEvery 20 min at the peak, 40 min off-peak
- Built on a survey of 310 respondentsPlus BIWTA and BIWTC operating data
Phase 4 · Safety · ICACE 2022
Forecasting crashes with unauthorized vehicles
Police-recorded crashes in Bangladesh involving unregistered local vehicles such as easy-bikes and nosimons, 2009–2015, modeled with ARIMA(6,1,7) to forecast 2016–2020.
Phase 5 · Research · MDOT · ITS Lab, WMU
What does a lane closure cost road users?
Research for the Michigan Department of Transportation: testing five traffic data sources to evaluate how MDOT estimates work-zone user delay and cost.

Phase 6 · Design competition · ITE Great Lakes District 2026
Winner: a turbo roundabout for a high-crash two-lane roundabout
B/C 1.12
Spiral lane dividers stop lane changes inside the circle. The design covered crash history, demand, pedestrians, signing and marking, and a 20-year benefit–cost analysis.
