Cities, broadly, manage a number of public assets with which they provide public services. Some of those services are somewhat passive in the sense that no active labor aside from maintenance is being carried out. And others are more active in that the asset is being used by public sector employees or contractors to provide a public service. We generally think of the latter as the primary mode of public service delivery as it is more visible. We see the bus driver, the police officer, the firefighter, etc in our communities doing their jobs. But the passive service is no less important. We drive on roads, use water and sewer infrastructure (though this is a blended service), etc on a daily basis as we go about our lives. One of the big differences between these two kinds of services is how the public sector asks users to pay for them. Some services are supported through taxes, but a great many are supported through user fees. Below, I point out two approaches to this for getting around a central city: the cost of storing a vehicle on a public street versus the cost of using the transit system.
