Innovative public transportation through digital twin technology
As cities like San Francisco continue to grow, finding safe, efficient, and sustainable transportation options is becoming more critical than ever. Innovative public transportation systems not only make it easier for people to move through densely populated areas but also help reduce congestion, improve safety, and lower emissions. In the face of climate change, encouraging commuters to choose the bus, train, or light rail is key to shaping the future of transportation.
Arcadis partnered with the San Francisco Municipal Transportation Agency (SFMTA), TNL Group, and Quanergy on a cutting-edge pilot project that tested new public transportation solutions in one of the city’s busiest neighborhoods. Over the course of a month, the pilot demonstrated how sensor-driven software can improve public safety, reduce traffic delays and idling times, and cut greenhouse gas emissions.
Using digital twin technology to enhance traffic flow
In Mission Bay, a real-time virtual representation of traffic—known as a digital twin—was created using LiDAR technology. This innovative model continuously captured traffic data and analyzed vehicle flow every few seconds. Using these insights, SFMTA adjusted 11 intersections in real time, resulting in:
- A 20% or greater increase in transit speeds
- A 72% reduction in red light delays for light rail vehicles
- A 17% faster average trip time for light rail services
- A 26% reduction in CO₂ emissions from shorter wait times
Shaping the future of transportation
This pilot illustrates the power of technology to redefine public transportation solutions for growing cities. By combining digital data with real-world traffic systems, city agencies can make evidence-based decisions that improve efficiency and sustainability at scale.
The project’s success in San Francisco shows that digital innovation can make public transportation faster, safer, and more appealing—while contributing to cleaner, more resilient communities for future generations.
