Active Travel Behavior and Spatial-Temporal Land Use Mixing

Steven Gehrke
Urban policies have emphasized the importance of land use mixing as an intervention beholding of lasting planning and public health benefits. Transportation planners have identified potential in efficiency gains achieved by increasing land use mix and the subsequent shortening of trip lengths; whereas, public health research has accredited increased land use mixing as an effective policy for facilitating greater physical activity. However, despite the myriad benefits and extent of topical res... Read More
