This Handbook has been prepared by the Iowa DOT as a guide and supplement to the MUTCD. It provides in one document a large number of illustrations which can be easily adapted to specific conditions by field personnel. It is intended to supersede all previous non-conforming standards now being used throughout the state and to provide uniform guidelines for all agencies, public and private, who must conduct construction and maintenance activities on the streets and highways of the state. The illustrations contained herein serve as a quick reference for field personnel to follow, however, no amount of detailed instructions can adequately cover every situation. For this reason, sound judgment is required in using these illustrations to cover actual field conditions.

This paper carries the rather weighty title of "Evolution of Design Practice at the Iowa State Highway Commission for the Determination of Peak Discharges at .Bridges and Culverts." Hopefully, this evolving process will lead to a more precise definition of a peak rate of runoff for a selected recurrence interval at a particular site. In this paper the author will relate where the Highway Commission has been, is now, and will be going in this art of hydrology. He will then offer some examples at a few sites in Iowa to illustrate the use of the various methods. Finally, he will look ahead to some of the pitfalls still lying in wait for us.

Poor air quality has a huge detrimental effect, both economic and on the quality of life, in Australia. Transit oriented design (TOD), which aims to minimise urban sprawl and lower dependency on vehicles, leads to an increasing number of buildings close to transport corridors. This project aims at providing guidelines that are appropriate to include within City Plan to inform future planning along road corridors, and provide recommendations on when mitigation measures should be utilised.
