Opticom Traffic Light System | Emergency Vehicle Priority Control for FiveM

Bring realistic emergency response mechanics to your server with the Opticom Traffic Light System. Inspired by real-world traffic preemption technology used by fire departments and EMS worldwide, this script gives emergency vehicles the power to change traffic lights to green as they approach intersections. No more waiting at red lights during critical calls - Opticom ensures emergency personnel can navigate Los Santos traffic efficiently and realistically, just like real first responders.

What Makes Opticom Stand Out

• Real-World Technology - Based on actual Opticom/GTT traffic preemption systems used globally
• Automatic Detection - Traffic lights detect approaching emergency vehicles and change automatically
• Configurable Range - Set detection distance per intersection (typically 100-300 meters)
• Multi-Directional - Turns approaching direction green while stopping cross-traffic
• Siren Requirement - Only works when emergency sirens/lights are active (prevents abuse)
• Framework Flexible - Compatible with ESX, QBCore, QBOX, or standalone servers

Perfect For

• Serious roleplay servers with active fire, EMS, and police departments
• Communities wanting realistic emergency response mechanics
• Servers focused on authentic first responder gameplay
• Public safety roleplay servers where response time matters

How Opticom Works

1. Activate Emergency Equipment - Turn on sirens and emergency lights in authorized vehicle
2. Approach Intersection - System detects vehicle within configured detection range
3. Light Changes Green - Traffic signal turns green in your direction of travel
4. Cross-Traffic Stops - Perpendicular directions turn red to clear intersection
5. Safe Passage - Emergency vehicle proceeds through intersection safely
6. Return to Normal - After vehicle passes, lights resume normal cycle

Key Features

• Vehicle Whitelist - Define which vehicles have Opticom access (fire trucks, ambulances, police)
• Job Restrictions - Limit functionality to specific jobs/departments
• Intersection Mapping - Configure which traffic lights support preemption
• Detection Zones - Set custom detection ranges per intersection type
• Priority Levels - Configure response priority (fire > EMS > police, etc.)
• Abuse Prevention - Requires active sirens, logs all preemption activations

Framework Compatibility

• ✅ ESX - Full integration with ESX job system and emergency jobs
• ✅ QBCore - Native QBCore support with job permission system
• ✅ QBOX - Compatible with QBOX framework
• ✅ Standalone - Can operate without framework using vehicle whitelist

Configuration Options

• Detection Range - Set how far away vehicles trigger preemption (100-500 meters)
• Activation Delay - Time delay before light changes (realistic 3-5 second transition)
• Hold Duration - How long green light stays active after vehicle passes
• Siren Requirement - Toggle whether sirens must be active for preemption
• Vehicle Whitelist - Define eligible emergency vehicle models
• Intersection List - Map which traffic lights support Opticom
• Job Permissions - Restrict to fire, ambulance, police, sheriff, etc.

Supported Emergency Vehicles

• Fire apparatus (engines, ladders, tankers, chiefs)
• Ambulances and paramedic units
• Police patrol vehicles and command units
• Sheriff department vehicles
• State patrol/highway patrol units
• Custom emergency vehicles (configurable)

Installation

1. Extract Opticom script to your server resources folder
2. Configure traffic light coordinates in config.lua (use coordinate helper tool)
3. Set detection ranges and activation requirements
4. Define authorized vehicles and jobs in whitelist configuration
5. Add ensure opticom to your server.cfg
6. Restart server and test with emergency vehicle on configured intersections

Technical Details

• Performance: 0.01-0.02ms resmon per active intersection
• File Size: Lightweight script under 5MB
• Dependencies: None required (framework integration optional)
• Compatibility: Works with most traffic light systems and map mods

Intersection Mapping

The script includes a coordinate helper tool for easy setup. Simply drive to each intersection, run the helper command, and coordinates are automatically logged. Major intersections in vanilla Los Santos are pre-configured, with support for custom MLO and map mod traffic lights through manual coordinate entry.

Roleplay Benefits

• Faster Response Times - Emergency services arrive faster during critical situations
• Realistic Operations - Mimics real-world emergency vehicle privileges
• Safer Pursuits - Police can navigate intersections safely during chases
• Fire RP Enhancement - Adds urgency to structure fire responses
• Medical Realism - EMS can transport critical patients faster

Why Emergency Services Love Opticom

For firefighters and paramedics, Opticom is a game-changer. Waiting at red lights during a cardiac arrest call breaks immersion and frustrates players trying to save lives. With Opticom, emergency response feels urgent and realistic - lights change as you approach, traffic clears, and you maintain momentum toward the scene. Police officers appreciate not having to blow through red lights during pursuits, reducing accident risks. It's one of those features that, once experienced, becomes essential to emergency roleplay.

Server Owner Benefits

Opticom solves the age-old problem of emergency vehicles stuck in traffic or causing accidents at intersections. It adds a layer of professionalism to your emergency services departments without requiring complex setup or performance-heavy systems. The abuse prevention features (siren requirements, job restrictions, logging) ensure only authorized personnel use the system properly. For servers serious about realistic emergency services RP, Opticom delivers authenticity that players notice and appreciate.

Logging & Administration

• Activation Logs - Track which players use Opticom and when
• Abuse Detection - Identify unauthorized usage attempts
• Usage Statistics - Monitor preemption frequency per intersection
• Performance Monitoring - Track system impact on server performance

Update Policy

Lifetime updates included with purchase. Regular updates add support for new maps, framework compatibility improvements, and feature enhancements based on real-world traffic preemption technology.
