Understanding Constraints

Constraints are the physical and regulatory limitations that affect route feasibility. RoadScope organizes constraints into categories for systematic analysis.

Constraint Categories

**Vertical Constraints** — Overhead obstacles that limit load height: bridges, overpasses, utility lines, signs.

**Horizontal Constraints** — Width limitations: lane widths, median barriers, guardrails, narrow structures.

**Geometric Constraints** — Turning limitations: intersection geometry, curb radius, approach angles.

**Grade Constraints** — Slope conditions: steep grades, transitions, surface conditions.

**Regulatory Constraints** — Non-physical limitations: permit requirements, time restrictions, escort needs.

Building Your Database

As you complete surveys, your constraint database grows. Each documented POI contributes to the route intelligence available for future routing decisions.

Maintaining Accuracy

Constraints change over time. Establish re-survey schedules and update records when conditions change. RoadScope tracks data currency and alerts you to aging data.
