Several different issue or problem categories are outlined in this paper followecl by a review of three· examples of internal circulation planning for major activity centers. The issue and problem categories include size and geographic dimensions, internal travel volumes, congestion levels, and special-purpose travel features. The examples include Post Oak Center in Houston, Woodlands Metro Center north of Houston, and Las Colinas in Irving, Texas. Potential negative impacts associated with internal circulation needs are described in association with (a) discontinuous or poorly designed facilities for pedestrian flow, and (bl excessive levels of internal automobile traffic. Remedies or solutions for these problems, as advanced in the three case studies, are evaluated; these remedies cover pedestrian improvements, automobile access and parking improvements, surface transit, and automated _guideway transit.
