We describe the CMU Sidewalk Navigation System, which can drive a vehicle in the outdoor environment of the CMU campus. The system includes all modules necessary for outdoor navigation .. modules for route planning, local path planning, vehicle driving, perception, and map data. The perception module uses sensor fusion with color and rage data to analyze complex outdoor scenes accurately and ef...

Outdoor allergens are an important part of the exposures that lead to allergic disease. Understanding the role of outdoor allergens requires a knowledge of the nature of outdoor allergen-bearing particles, the distributions of their source, and the nature of the aerosols (particle types, sizes, dynamics of concentrations). Primary sources for outdoor allergens include vascular plants (pollen, f...

Following an extensive review of the literature, we further analyze the published data to examine the health effects of indoor exposure to particulate matter (PM) of outdoor origin. We obtained data on all-cause, cardiovascular, and respiratory mortality per 10 μg/m3 increase in outdoor PM10 or PM2.5; the infiltration factors for buildings; and estimated time spent outdoors by individuals in th...

PURPOSE We examine whether fear, victimization, and perceived incivilities are associated with physical activity and outdoor recreation among Latino youth and whether involvement in physical activity is associated with delinquen...

Despite calls for a systems approach to assessing and preventing injurious incidents within the led outdoor activity domain, applications of systems analysis frameworks to the analysis of incident data have been sparse. This article presents an analysis of 1014 led outdoor activity injury and near miss incidents whereby a systems-based risk management framework was used to classify the contribu...
