CASE STUDIES
Preventing Flood-Related Subway Accidents with AI-Driven Vehicular Access Control
The client
A major municipal corporation responsible for managing a busy metropolitan subway network. During monsoons, these subways often flood without warning, putting commuters, vehicles, and public infrastructure at serious risk. The city needed a modern, automated way to prevent vehicles from entering inundated zones.
The Challenge
Seasonal rains caused rapid water accumulation in single-lane and double-lane subways, creating hazards and leading to frequent traffic disruptions. Traditional monitoring methods relied on manual inspection and human response time - both too slow for fast-rising water levels.
They needed a solution that could:
- Detect rising water levels instantly.
- Automatically close subways before vehicles entered.
- Alert the public in real time.
- Reopen routes safely once conditions improved.
- Record all events for analysis and planning.
AL Based Vehicular Access Control System
An AI-powered Vehicular Access Control System (VACS) was deployed to automate the entire flood- response workflow.
IoT flood sensors, edge computing, and intelligent barriers work together to prevent accidents and keep commuters informed.
Real-Time Monitoring
OTP-based access eliminates traditional keys and prevents unauthorized entry.
Automated Subway Closure
When water crosses a safe threshold, boom barriers activate automatically to stop vehicles from entering.
Smart Reopening
Barriers retract as soon as levels recede, restoring traffic flow without manual intervention.
Public Communication
Digital signboards display warnings, while pre-configured voice alerts guide commuters.
Manual Override
Local authorities can control barriers from a mobile app for emergency or maintenance needs.
Data Logging and Insights
Every event is recorded and available to city officials for analysis, reporting, and future planning.
Key Features and Benefits
