This supplementary material provides additional illustrations, visualizations and experiments. We start by showing the color coding and label mapping used for the semantic and instance label results in the paper. Then we provide more details about the 3D fold/curb detection and parameter settings that are used in the paper. Next, we provide additional quantitative and qualitative semi-dense inf...

This work examines the relationship between 3-year pedestrian crash counts across Census tracts in Austin, Texas, and various land use, network, and demographic attributes, such as land use balance, residents' access to commercial land uses, sidewalk density, lane-mile densities (by roadway class), and population and employment densities (by type). The model specification allows for region-spec...

This study aims to evaluate economic and environmental benefits of porous pavement surface using life-cycle cost analysis (LCCA) and life-cycle assessment (LCA). The research will focus on application of porous surface for sidewalk. The life-cycle inventory data were collected from literature search, online database, and project records. The comparison study was conducted between pervious pavin...

Walking speed was timed for male and female pedestrians on a public sidewalk with fast, slow, or no music playing in the background (n = 20 per condition). Pedestrians in the fast music condition walked more rapidly than those in the other two conditions. Slow music did not reduce walking speed, relative to the no music condition. Walking speed did not differ by gender in any of the three condi...

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...
