Traffic count data is collected by the St. Lucie Transportation Planning Organization(TPO). The TPO is not a level of government, rather it provides a forum through which all traffic_count_pic1levels of government work together to identify and address local, county and regional transportation needs. These needs include not only roads and highways but also public transportation, bike paths, sidewalks, movement of freight and perhaps one day, passenger rail service. The St. Lucie TPO is responsible for helping coordinate transportation planning, programming, and financing of state and federal transportation funds for the three municipalities and unincorporated areas of St. Lucie County. As part of this role, the St. Lucie TPO prepares short and long-range transportation plans, which identify the need, timing, and phasing of future transportation improvements.
