## 1. Executive Summary & Geographic Context
**JunctionAI** is a production-grade, full-stack Intelligent Traffic Control System (ITCS) developed for **Ekpo-Abasi Junction**, situated in **Calabar South Local Government Area, Cross River State, Nigeria**.
Ekpo-Abasi Junction is a vital, high-density traffic nexus connecting:
- **Approach 1 (Northbound)**: Ekpo-Abasi Street (Approach from the main entrance of Cross River University of Technology - UNICROSS / CRUTECH).
- **Approach 2 (Southbound)**: Ekpo-Abasi Street (Approach from the Calabar South commercial district and Watt Market corridor).
- **Approach 3 (Eastbound)**: Mayne Avenue Link (Approach from the Anantigha Coastal Bypass).
- **Approach 4 (Westbound)**: Saintaggers / Target Street Link (Approach from Mary Slessor Avenue).
Traditional traffic control in this corridor relied on static, fixed-time signal switching or manual traffic warden intervention. This created severe structural inefficiencies, notably **Empty Lane Syndrome** (where a signal remains green for an empty approach while adjacent congested legs back up), a total **Absence of Emergency Vehicle Priority** (ambulances to General Hospital Calabar or UNICROSS Medical Center stuck in gridlock), and **Poor Historical Data Collection**.
JunctionAI resolves these challenges through a unified real-time adaptive timing engine, an emergency preemption state machine, a dedicated pedestrian safety coordinator, and a centralized audit telemetry system.
