The first part of a series on San Antonio, TX, USA -- site of the ITE 2009 Annual Meeting and Exhibit -- focuses on a unique median design solution where three roadways plus a heavily-used driveway to a shopping center all intersected in one location. Preliminary models of the "peanut-about" have shown a significant reduction in travel time through the intersection. The conflict was exacerbated by the fact that two of the roads were heavily traveled arterials intersecting at a severe angle. In early years, the intersection was successfully operated with a traffic signal, but increased traffic had led to serious congestion. Preliminary models of the 'peanut-about' have shown a significant reduction in travel rime through the intersection. When engineers utilize standard details, computer generated models, or computations without thoroughly understanding the concepts on which they are built, they sell themselves short.
