AI Route Planning

Executive Summary

Choosing the wrong route is expensive. Each extra crossing, dig, or private-way permit adds cost and delay. An AI route planner turns layered GIS data into an optimized, costed corridor: it builds a graph from roads, ducts, poles, railways, water, protected areas, and no-go zones; assigns costs and risks; and proposes ranked alternatives (shortest, lowest cost, or fewest permits). For each option it generates a bill of quantities, highlights permit requirements, and exports a submission pack. Humans review trade-offs and finalize the plan.

The problem today

Planning teams juggle multiple maps, spreadsheets, and legacy tools. Cost factors (surface type, depth, traffic management) are estimated inconsistently. Permit implications are discovered late, triggering redesigns. As schedules slip, crews wait and CAPEX rises.

The AI-led flow

1. Data fusion: Import roads, ducts, poles, utilities, parcel boundaries, environmental layers, traffic classes, and permit jurisdictions into a unified geospatial model.
2. Costing & constraints: Assign cost weights (dig types, reinstatement, traffic control) and encode constraints (no-dig zones, river/rail crossings, easements).
3. Route optimization: Run shortest-path / MILP with multi-objective scoring (cost, duration, risk). Output top 3–5 alternatives with metrics and heatmaps.
4. What-if analysis: Adjust weights (e.g., “minimize permits” vs “minimize dig length”) and instantly re-rank options.
5. Permit preview & BoQ: For each alternative, list permit types and authorities, expected SLAs, and generate a preliminary BoQ with unit costs.
6. Submission package: Export maps, KML/GeoJSON, BoQ, and a narrative for approvals; open tasks route to permitting and construction planning.
7. Change tracking: When constraints or costs change, the system flags impacted segments and proposes re-routes.

Privacy-by-design, compliance-aligned: Use only necessary geodata, enforce data residency, and retain audit trails of assumptions and cost factors. The planner provides decision support; final routing decisions remain with engineering and permitting teams.

Pilot scope (4–6 weeks)

• Scope: 1–2 corridors (20–60 km) with mixed urban/suburban segments.
• Interfaces: Read from GIS sources; export GeoJSON/KML, BoQ CSV, and permit checklists.
• Success criteria: Estimated CAPEX vs. baseline, number of permits, projected build time, and redesign cycles.

Hypothesis metrics (illustrative, not guaranteed):

• CAPEX −5–15% through optimized corridors.
• Permits per km −10–25%.
• Route redesign cycles −30–50%.

Quick ROI math (scenario):
On a €12M build, a 7% corridor saving ≈ €840k. Even after software/ops costs, payback is typically within one planning season.

Risks & mitigations

• Incomplete geodata: Flag data freshness, allow manual overrides, and show confidence levels.
• Local rules variability: Jurisdiction-specific templates and checklists; human review before submission.
• Over-optimization: Keep human-in-the-loop with transparent cost weights and constraints.

From pilot to scale

Expand to regional portfolios, integrate with permit automation and contractor scheduling, and add environmental scoring (noise, emissions). Over time, route design becomes faster, cheaper, and more predictable.

Expected impact (illustrative):

• Reduced CAPEX through optimized build routes.
• Faster rollout thanks to fewer permitting and construction hurdles.
• More sustainable planning with minimized impact.
• ROI from construction and permitting savings.
