API Reference

The trafficpipeline package exposes the following modules:

Module	Description
config	City definitions, time periods, constants
utils	Timestamp extraction, geometry hashing, filters
aggregate	Raw GeoPackage → time-period aggregation
eda	Data validation & exploratory analysis
geostatistics	Spatial statistics & hot-spot analysis
bottleneck	Road-capacity bottleneck analysis (OSMnx)
poi	POI-congestion density analysis
synthesis	Temporal vs spatial predictor comparison
multilevel	Multilevel variance decomposition (mixed-effects models)
markov	LISA Markov & Spatial Markov transition analysis
speed_validation	Speed-based validation across congestion metrics
h3_robustness	H3 hexagonal aggregation for MAUP robustness
positive_control	Positive control: free-flow vs current speed R²
