Measurement and evaluation
Compliance rate
Taux de conformité
Compliance rate is the proportion of observed actions or sessions that meet specified rules during a defined period. Curb compliance can concern eligibility, payment, duration, or stopping location, and each dimension needs a clear denominator rather than a single percentage that conceals different types of violations.
Understanding the term
An enforcement citation count is not a compliance rate. It also reflects patrol coverage, detection practices, and discretion, which can change independently of user behavior.
Every reported measure needs a geographic boundary, observation period, unit, and documented calculation method. State how missing data, temporary closures, and sessions crossing the observation boundary are treated. Use distributions or separate user categories where an average hides important differences. Compare consistent definitions across sites and periods, and distinguish an observed association from a demonstrated causal effect. The appropriate indicator follows the policy question rather than whichever field a monitoring system happens to provide.
