Transit & Ridership

APC data processing & NTD reporting

Transit agencies collect millions of boarding and alighting records from automatic passenger counters every month. But raw APC data doesn't become useful ridership information on its own. It needs to be ingested, matched to scheduled trips, validated against configurable quality rules, and processed into the metrics that NTD reporting requires.

Without an automated pipeline, agencies rely on manual processes that are slow, error-prone, and opaque. Analysts spend weeks preparing NTD submissions. Route-level ridership trends remain invisible. Planning teams cannot access validated data through APIs. And when validation rules change, there is no way to preview the impact before it reaches final reports.

Transit agencies need a platform that turns raw APC data into validated, NTD-compliant ridership metrics — with full traceability from sensor to report.

The Current State

01Raw APC data arrives daily from counting systems like Clever Devices, Dilax, or Eurotech but sits unprocessed because there is no automated pipeline to match trips, validate counts, and produce usable ridership metrics
02No configurable validation rules to catch zero-count trips, negative passenger loads, capacity exceedances, or boarding/alighting imbalances before they corrupt reports
03NTD reporting is a manual, error-prone process — analysts spend weeks assembling UPT, PMT, Revenue Miles, and Revenue Hours from spreadsheets and disconnected data sources
04Route-level ridership patterns are invisible because stop-level boarding and alighting data is never aggregated, mapped, or compared across time periods
05No programmatic access to ridership data — planning teams, external systems, and reporting tools cannot pull validated metrics through a standard API
06Data factoring and sampling adjustments are opaque — agencies cannot see how adjustments affect final NTD numbers or trace calculations back to source data

What We Bring

An end-to-end APC data processing platform that replaces manual workflows with automated ingestion, validation, and reporting.

Data Ingestion

Automated SFTP ingestion from Clever Devices, Dilax, Eurotech, Infodev, and other APC vendors. Trip matching against GTFS schedules and stop-level aggregation.

Data Validation

Configurable validation rules with impact preview. Catch data quality issues before they reach reports.

NTD Reporting

Generate NTD-compliant UPT, PMT, Revenue Miles, and Revenue Hours with configurable factoring and sampling.

Route Analytics

Interactive maps with stop-level ridership, on-time performance distributions, and trend analysis across periods.

API Access

24+ REST endpoints with OAuth2 authentication, OpenAPI documentation, and code examples for integration.

Diagnostics

Sensor health monitoring, zero-count detection, negative load alerts, and system-wide processing diagnostics.
