What asset management and digital engineering do on transportation infrastructure.
A use-case catalog organized by infrastructure class — highways and bridges, rail networks, airports,
ports, and urban transit. Each card names the application, what it runs on, and what it changes in
operations.
AM — asset management capabilityDE — digital engineering capabilityCross-cutting platform capability
CLASS · 01 Highways & Bridges
Vast networks, thin budgets — condition data decides where the money goes.
Road agencies manage tens of thousands of lane-miles and thousands of structures on
maintenance budgets that cover a fraction of the theoretical need. The high-value use cases turn
condition measurement into treatment prioritization.
Bridges, pavements & earthworks
Structures · Pavement network · Slopes & drainage
DE · SHM
Structural health monitoring on critical bridges
Strain gauges, accelerometers, tilt and displacement sensors on long-span, fracture-critical, or heavily loaded structures, trended against baseline behavior to detect stiffness loss, bearing seizure, and abnormal response.
Runs onStrain/acceleration/tilt sensors, weather data, structural baseline model
ChangesInterventions triggered by measured behavior; emergency closures pre-empted
DE · Inspection tech
Drone bridge inspection with defect mapping
UAV imagery of decks, soffits, bearings, and cables processed by vision models to detect and grade cracking, spalling, and corrosion staining — mapped onto a 3D model so defects are tracked between cycles.
Runs onUAV imagery, photogrammetry model, defect taxonomy, prior inspection records
Structure capacity analysis kept current with condition findings to set legal load postings and clear superload permit routes — the legal decision that condition data must feed.
Runs onAs-built records, inspection findings, live-load models, permit systems
ChangesDefensible postings; permit routing automated against current capacity
DE · Survey analytics
Vehicle-mounted pavement condition surveys
LiDAR, imaging, and profilometer data collected at traffic speed, with ML extracting cracking, rutting, and roughness (IRI) network-wide every year instead of sampled windshield surveys.
ChangesFull-network condition annually; treatment selection on measured distress
AM · Lifecycle
Pavement lifecycle & treatment optimization
Deterioration models and treatment cost curves optimizing the mix of preservation, rehabilitation, and reconstruction across the network — the “right treatment, right road, right time” engine behind the capital program.
ChangesNetwork condition held or improved on flat budgets; backlog made visible to funders
AM · Geohazard
Slope, embankment & scour monitoring
InSAR satellite deformation, in-ground sensors, and post-storm scour assessment prioritizing geotechnical intervention along corridors — the failure mode that closes roads with no warning.
Runs onInSAR time series, piezometers/inclinometers, hydraulic scour models
ChangesSlope failures and scour-critical bridges intercepted before closure events
CLASS · 02 Rail Networks
Track and train degrade each other — the best use cases measure both.
Rail is the most instrumented transportation mode: geometry cars, wayside detectors,
and onboard telemetry generate continuous condition data on both infrastructure and rolling stock.
Track, rolling stock & systems
Permanent way · Fleet · Signaling · OLE
DE · Analytics
Track geometry degradation prediction
Repeated geometry-car and in-service (axle-box accelerometer) measurements modeled per track segment to forecast when alignment, gauge, and twist will breach intervention limits — converting tamping from cyclic to predictive.
ChangesTamping/renewal scheduled by forecast breach; temporary speed restrictions reduced
DE · Wayside sensing
Wayside vehicle-health detectors
Hot axle box, wheel impact load, acoustic bearing, and pantograph-camera installations screening every passing train — catching failing wheelsets and bearings before derailment-class events.
Runs onWILD/HABD/acoustic arrays, vehicle ID (RFID), fleet maintenance systems
ChangesDefective vehicles intercepted en route; wheel damage to track reduced
DE · Predictive ML
Rolling stock predictive maintenance
Onboard telemetry from traction systems, doors, HVAC, and brakes modeled against failure history — doors and HVAC being the classic availability killers on passenger fleets.

ChangesIn-service failures down; maintenance moved into planned depot slots
AM · Renewal
Rail defect, grinding & renewal planning
Ultrasonic and eddy-current defect data with rolling-contact-fatigue models driving the grinding program and rail renewal sequence — managing the asset that fails catastrophically when managed badly.
ChangesBroken-rail risk ranked network-wide; grinding cycles set by measured wear
DE · Twin
Network digital twin for capacity & possession planning
A connectivity-accurate network model used to simulate timetables, test possession (track-access) strategies, and quantify the service impact of works before they’re booked.
Runs onNetwork model, timetable data, works bank, historical performance data
ChangesPossessions batched for least disruption; works-vs-service trade-offs quantified
AM · Systems
Signaling & OLE asset health and obsolescence management
Condition, failure, and spares-obsolescence data across interlockings, level crossings, and overhead line prioritizing the renewals ladder for the assets that cause the most delay minutes per failure.
Runs onFailure/delay attribution data, asset age & type registers, spares availability
ChangesRenewals aimed at worst delay-per-failure assets; obsolescence risk surfaced early
CLASS · 03 Airports
A power plant, a shopping mall, and a runway in one fence line.
Airports concentrate airfield civil assets, building systems, and high-throughput
machinery — with availability measured in delayed flights and missed connections.
Airfield, terminals & handling systems
Runways · BHS · Gates · Building systems
AM · Airfield
Airfield pavement management (PCI-based)
Pavement condition index surveys, friction testing, and deflection data driving the rehabilitation program for runways and taxiways — where works can only happen in short night closures.

DE · Detection
Automated FOD & runway surface monitoring
Radar and camera systems continuously scanning runways for foreign object debris and surface anomalies, replacing periodic vehicle sweeps between movements.

BMS data with occupancy and flight-schedule forecasts tuning heating, cooling, and air handling — terminals being among the most energy-intense building types per square meter.
Runs onBMS/BAS data, flight schedule, occupancy sensing, energy meters
ChangesEnergy cost per passenger down; comfort complaints and plant cycling reduced
AM · Gate assets
Gate equipment reliability programs
Condition and failure data on jet bridges, ground power, and pre-conditioned air units prioritizing overhaul and spares — the assets whose failure holds an aircraft at the gate.
ChangesGate-caused turnaround delays cut; overhaul spend aimed at worst actors
DE · Twin
Terminal digital twin for flow & works planning
A 3D/BIM-based terminal model with passenger-flow simulation used to plan capacity works, security reconfigurations, and construction phasing without degrading live operations.
ChangesWorks phased without queue breaches; capacity options tested before capital commitment
CLASS · 04 Ports & Maritime
Heavy machinery on marine structures in a corrosive environment.
Ports combine crane fleets working around the clock with quay walls and berths that
are largely invisible below the waterline — and throughput contracts that penalize every idle hour.
Cranes, berths & marine structures
STS/RTG fleets · Quay walls · Channels & locks
DE · Condition monitoring
Crane (STS/RTG) drive & structure monitoring
Hoist and trolley drive telemetry, brake wear, and structural strain monitoring across the crane fleet — predicting failures on the machines that set the berth’s productivity ceiling.

CLASS · 05 Urban Transit
Metro, bus, and the vertical assets in between.
Transit agencies run rail-grade infrastructure plus building-grade stations plus a
road fleet — with state-of-good-repair backlogs that make prioritization the core discipline.
Fleet, stations & tunnels
Metro & bus fleets · Vertical transport · Civils
DE · Predictive ML
Escalator & elevator predictive maintenance
Drive current, vibration, and door-cycle data on the vertical transport fleet — the asset class riders notice first and the top accessibility-compliance exposure.

PLATFORM · 06 Cross-Cutting Capabilities
The layer underneath every use case above.
Four platform capabilities determine whether the asset-class use cases scale beyond
pilots. Weakness here is the usual reason individual use cases stall.
Platform · P-01
Asset registry, GIS & BIM data foundation
A single trusted inventory — linear referencing for networks, BIM for structures and stations, condition history attached to the right asset. Every analytics use case inherits its quality ceiling here.
Applies to: every use case in this catalog; the first investment when data is split across inspection binders, spreadsheets, and legacy systems.
Platform · P-02
OT/IT integration & data historians
Governed movement of SCADA, signaling, BMS, and vehicle telemetry into analytics environments — contextualized to asset and location, not raw tag streams.
Applies to: all condition-monitoring, telematics, and twin use cases; the usual bottleneck between pilot and network-wide rollout.
Platform · P-03
OT & safety-system cybersecurity
Segmentation and integration governance for signaling, traction power, tunnel systems, and airport/port control networks — every sensor added above widens the surface this must hold.
Applies to: any use case touching signaling, SCADA, or building/industrial control; non-negotiable for safety-critical rail and airfield systems.
Platform · P-04
Decision-support / EAM integration layer
Where condition data, deterioration models, and risk logic converge into work orders, renewal programs, and funding cases inside the EAM/works-management system.
Applies to: converting every detection use case into scheduled, costed intervention — the last mile that realizes the value.
