For instance, CTA intends to use intercept surveys to validate its electronic fare cardbased O-D model. By providing service delivery data covering an entire transit system, ITS data provide useful inputs for intercept surveys; at the same time, intercept surveys also provide key data inputs to support models estimated from ITS data.
