This is kinda three different problems, or three effects from one problem:
Being stuck in traffic has a negative impact on health, quality of life in general
Being stuck in traffic has a monetary cost for deliveries and others who have travel as a significant part of their work, e.g. how easy it is for plumbers to get around to customers and warehouses and the like
Being stuck in traffic can have terrible consequences for emergency services
The solutions, of course, are a mix of negative incentives to drive like congestion and parking pricing, and positive incentives to not drive, like investing in transit, cycling, mixed use and at least a certain level of urban density to be able to support transit, services and not have biking and walking be unfeasible or undesirable because of long distances.
