This report gives a preliminary cost benefit factor analysis for Automatic Highway Systems (AHS) implementation on a representative section of existing highway. The text describes the approach used to develop cost associated with the roadway portion of AHS and gives cost estimates for 5 basic implementation options: install `transparent equipment in roadway` that will give performance gains to those vehicles equipped to `see` it (e.g. magnetic nails); move towards separated roadway for AHS rumble strips or paint, then fully separated with either continuous barriers with dedicated entry/exit ramps or separate facility such an elevated structure; expand AHS capabilities further so AHS traffic can now use existing roadways with other traffic and formerly dedicated facilities can be converted to higher speed through traffic. However, the actual implementation will necessarily be a function of local roadway geometry, system demand, and a complex combination of other factors. Very few existing roadways can accommodate these specific conversions directly. Therefore, we have generated roadway retrofit options that can be used depending on local geometry to support this general evolution philosophy.
