Density Perception on Residential Streets

Matching Range Images of Streets with a Residential Map

In order to realize 3D modeling and refinement of buildings in a digital 2D residential map using range images of the streets, we match range images of streets with the digital map. After pattern lines of the range images are determined using edge detection and depth analysis, they are matched with pattern lines of the digital map using a pattern matching algorithm based on dynamic programming....

Marking Streets to Improve Parking Density

Street parking spots for automobiles are a scarce commodity in most urban environments. The heterogeneity of car sizes makes it inefficient to rigidly define fixed-sized spots. Instead, unmarked streets in cities like New York leave placement decisions to individual drivers, who have no direct incentive to maximize street utilization. In this paper, we explore the effectiveness of two different...

Vortex Streets on a Sphere

The influence of crowd density on the sound environment of commercial pedestrian streets.

Commercial pedestrian streets are very common in China and Europe, with many situated in historic or cultural centres. The environments of these streets are important, including their sound environments. The objective of this study is to explore the relationships between the crowd density and the sound environments of commercial pedestrian streets. On-site measurements were performed at the cas...
