Title: Upgrade of the Mexican standards for the geometric design of highways
Abstract: In its origins, the standards for the geometric design of highways worldwide were generated from assumptions related to the conditions under which the vehicular operation would be adequate and safe, as well as from a series of field tests aimed at studying the vehicular behavior for the vehicles and prevailing conditions at that moment. Thus, the first manuals and norms incorporated many assumptions but very little experience on the real behavior of the vehicles operating on the highways. In Mexico, the existing manuals and norms were elaborated more than 30 years ago; this is a reason why they incorporate a great amount of assumptions and very few experiences on real vehicular behavior. Also, with the passing of the years, the vehicles and the prevailing conditions have varied significantly. In this work some key recommendations for upgrading the Mexican standard for the geometric design of highways are presented. The recommendations were generated from the comparison of the Mexican standard with standards of some more advanced countries in the matter as well as from the most recent studies and world approaches, and particularly the Mexican ones on different safety aspects.
