STrM1

STrM1 is an acronym for Smart Traffic Routing Module 1, a modular software framework for real-time urban traffic management and simulation. It provides an end-to-end stack to ingest data from traffic sensors, cameras, and connected vehicles, process information, implement routing and signal-control decisions, and actuate traffic signals and variable message signs. The architecture is layered into input adapters, a core decision engine, and an output/controller layer. The core engine supports event-driven processing, state estimation, and optimization modules that can be swapped or extended without changing the rest of the system. STrM1 emphasizes modularity, scalability, and interoperability, using open interfaces and standard communication protocols to connect with existing controllers, sensors, and data platforms.

The platform ships with multiple built-in modules, including traffic flow estimation, incident detection, and configurable objectives such as minimizing travel time, reducing queue lengths, or balancing network-wide objectives. It supports plug-ins for alternative routing policies, machine-learning–based predictions, and adaptive signal timing strategies. Simulation and emulation tools allow scenario testing, calibration, and performance evaluation before deployment in live networks.

Deployment and impact: STrM1 has been piloted in several urban areas and has informed adaptive signal control programs and incident response workflows. It is designed to operate in centralized or distributed configurations and to preserve data privacy and security through role-based access and encrypted communications.

Development and ecosystem: Originally developed by a collaboration of researchers and city partners, STrM1 is maintained through periodic public releases and a community forum for sharing modules and best practices.
