Bridge & Restricted Route Protection.

Protect infrastructure. Ensure safety. Enforce compliance.

An intelligent platform that prevents over-height, over-weight and unauthorized vehicles from entering vulnerable infrastructure and restricted routes — stopping damage before it happens.

What it does

Six capabilities, one platform.

Capability · 01
Height Detection

Accurate overhead clearance detection using laser/RF sensors and cameras — even at highway speed.

Capability · 02
Weight Monitoring

Detect over-weight vehicles using WIM (weigh-in-motion) or static weigh integration.

Capability · 03
ALPR & ANPR

Automatic license plate recognition for permit verification, blacklists and access control.

Capability · 04
Restricted Route Control

Enforce route restrictions, permits and time-of-day access rules across the network.

Capability · 05
Real-Time Alerts

Instant alerts and automated actions — barriers, dynamic message signs — to stop non-compliant vehicles.

Capability · 06
Analytics & Reporting

Dashboards and reports for enforcement, compliance and infrastructure-asset protection.

How it works

Four steps, continuous loop.

01 / Detect
Sensors & cameras.

Height, weight, vehicle classification and plate read — at full traffic speed, in any weather.

02 / Match
Rules & permits.

Compare against permit databases, blacklists, restricted-route rules and time-of-day windows.

03 / Act
Stop the violation.

Trigger barriers, dynamic message signs, alerts to enforcement and automated notice issuance.

04 / Measure
Asset protection KPIs.

Prevented entries, prevented strikes, cost-of-damage avoided, revenue from permits and fines.

Challenge · Solution · Results

The shift, in one frame.

Challenge

Where most public-sector operations lose efficiency and revenue today.

  • Over-height or over-weight vehicles cause bridge and road damage
  • Unauthorized or non-permitted vehicles use restricted routes
  • Limited visibility and manual enforcement
  • High maintenance and repair costs
  • Safety risks for road users and communities
Our solution

Bridge & Restricted Route Protection — capture, classify, act, measure.

  • Automated detection of height, weight and vehicle classification
  • Permit verification and access control using ALPR
  • Real-time alerts with automated barriers, signals and message signs
  • Centralized platform with dashboards, reports and analytics
  • Integration with enforcement, payment and permit systems
Results

Measured across deployments with cities, agencies, and operators.

  • 90%+ Reduction in bridge impacts
  • 85%+ Prevention of non-compliant entry
  • 30%+ Reduction in enforcement costs
  • 25%+ Faster response time
  • Safer roads and protected infrastructure
Integration

Connects to systems cities already run.

Bridge & Restricted Route Protection ships with reference connectors for the systems and devices that public-sector operations already rely on. Anything custom is added during deployment — we operate on top of your existing stack and don't ask you to rip-and-replace.

Featured outcome

Infrastructure damage prevented at the source, not at the repair desk.

Highway operator · WIM + Bridge Protection · multi-corridor

Infrastructure damage prevented at the source, not at the repair desk.

A highway operator deployed NUMU Bridge & Restricted Route Protection across multiple corridors. High-speed sensor capture, ALPR, and rule-based action — barriers, message signs, automated notices — stop non-compliant vehicles before they reach vulnerable infrastructure. Maintenance backlogs shrink; safety improves; enforcement becomes preventive rather than reactive.

  • Real-time detection at corridor scale.
  • Automated action: barriers, signage, notices.
  • Integrated violation management and revenue flow.
