Among the many works focusing on the city level, the PROPOLIS Report [56], the TRANSPLUS Report [57] and the PROSPECT Report [58] present some successful good practices connecting measures in land use and urban transport, and develop specific strategies and indicators to achieve SM.
We used data from the U.S. Environmental Protection Agency's Aerometric Retrieval System (Nehls and Akland 1973) to estimate the daily mean concentrations of ozone (8-hr) in 26 cities using an algorithm that averaged levels reported by multiple monitoring locations (Schwartz 2000).
