HANDBOOK OF SIMPLIFIED PRACTICE FOR TRAFFIC STUDIES

This handbook describes simplified procedures that are easy to apply and are written for all potential users (civil engineers and traffic engineers, public works mangers, city managers and attorneys, and the general public). The handbook has two primary objectives: The first objective is to develop a handbook of traffic studies that is convenient for Iowa jurisdictions to use in assessing traffic issues. The second objective is to develop a series of boilerplate scopes of work that local jurisdictions can use to hire outside consulting firms to perform traffic studies. The handbook is organized into chapters, one chapter for each of the studies presented: Spot Speed, Traffic Volume Counts, Sight Distance, Crash Analysis, and School Zone Program. Each chapter includes an introduction to the study type, step-by-step instructions for each common method of conducting the study, real-world examples, a model project work order for contracting out, and references. Appendixes provide additional resources and blank data-collection forms and project work orders that can be used or modified by local jurisdictions.
