HOW TO LEGALLY ESTABLISH ABSOLUTE SPEED LIMIT ZONES
This presentation outlines the procedures and conditions required in Indiana for speed survey used to establish proper speed limits. The speed study should be conducted during off-peak hours and such surveys include at least 100 vehicles in each direction or a two-hour time period, whichever comes first. After the survey is completed, the data from the "Speed Check Filed Sheet" which includes the location, day, date, time, direction, pavement width, weather, road surface condition, type of pavement and sight distance is checked for the 85% speed and pace rate. This analysis is used to request the posting of speed for the selected section of highway surveyed. Of course past accident information is considered and is used as part of the guidelines in the total survey. After the results of the survey are completed, a request for a change of speed can be made in the form of an "ordinance" to the "local authorities" with the data attached listing the recommended speed. The ordinance is then advertised in two local newspapers of different political faiths at two time periods of one to two weeks apart. At the completion of this time and advertisement factor, the established speed limit becomes an enforceable law.
