FlowVía: A Technical Deep Dive into Next-Gen Urban Mobility

This is a summary. Read the full article on Substack.

FlowVía is a concept for smarter urban mobility built on V2X (vehicle-to-everything) communication: V2V for inter-vehicle data sharing, V2I for interaction with traffic signals and roadside infrastructure, and V2N for cloud connectivity. It targets the two dominant protocol standards — DSRC in the 5.9 GHz band and C-V2X over cellular networks.

System architecture

The system has four primary components: an in-vehicle device with GPS and V2X modules, a mobile application for the user interface and sensor data collection, a cloud backend for machine learning and data aggregation, and integration with city infrastructure through roadside units.

Algorithms and data processing

Two core algorithms drive the experience: a speed-recommendation algorithm that computes optimal velocity from the distance to the next traffic signal and its time-to-green, and a traffic-flow prediction model using LSTM neural networks implemented in TensorFlow.

Privacy and security

The design emphasizes AES-256 encryption, rotating vehicle identifiers to prevent tracking, prioritizing local on-device processing, and secure boot implementations.

Open challenges

Latency management, scaling to millions of vehicles, interoperability across vendor systems, edge-case handling, and regulatory compliance remain the critical problems for real deployment.
