The Challenge

A mixed-use development in Double Bay needed to comply with council-mandated safety standards. The car park exit directly led onto a busy footpath, creating a blind spot where pedestrians couldn’t see oncoming vehicles. The tight timeline and strict noise requirements added complexity — the alarm could only sound during daytime hours.

Tailored Solution by Smart Traffic Systems

1. Site Survey & Design

  • Conducted a detailed on-site inspection to determine optimal locations for sensors, alarms, and visual aids.

2. Photoelectric Sensor System

  • Installed infrared photoelectric (PE) sensors across the exit lane. When a car interrupts the beam, it triggers the system.

  • Connected to a robust PLC that can be tailored to client-specific needs.

3. Audio-Visual Alarm Setup

  • Positioned synchronized strobe lights and sirens on either side of the exit.

  • Configured alarms for daytime hours only (silent after 7 pm), and wired the system to avoid false-triggering from pedestrians.

  • Optional LED signage with custom warning text added for extra visibility.

4. Custom Settings & Commissioning

  • Warning duration was customizable (typically ~15 seconds), with visual-only alerts during off-hours.

  • System tailored specifically to the building’s design and pedestrian flow.

Results & Benefits

Key Outcome Details
Hazard Reduction Significant minimization of collision risk at the blind-sided exit point.
Compliance with Council Rules System met all regulatory requirements, including noise curfews.
Rapid Deployment Fully installed within days, across multiple daylight shifts.
User-Friendly Automatic activation avoids false positives; simple system maintenance.

Why This Worked

  • Precision engineering with PLC and PE sensors ensured reliability and minimal false alarms.

  • Configurable alerts met both safety and community comfort needs (audible only during permitted hours).

  • Visual aids like strobes and optional signage increased effectiveness in busy pedestrian areas.

Broader Applications

This setup is ideal for:

  • Shopping centres & mixed-use precincts

  • Hospitals, schools & childcare centres near pedestrian zones

  • Council-owned car parks and transport hubs
