Investigation of Parking Lot Pavements to Counteract Urban Heat Islands

From Parking Lot to Paradise.

Reversible polydisperse parking lot model.

We use an improved reversible parking lot model to study the compaction of vibrated polydisperse media. The particle sizes are distributed according to a truncated power law. We introduce a self-consistent desorption mechanism with a hierarchical initialization of the system. In this way, we approach densities close to unity. The final density depends on the polydispersity of the system as well...

Reduction of Urban Heat Island Effect through Harvest of Heat Energy from Asphalt Pavements

Asphalt pavement surfaces contribute significantly to the urban heat island effect. Their relatively high temperature, caused by absorption of solar energy, results in emission of heat to the surrounding air, leading to a rise in its temperature, deterioration of its quality, and an increase in energy consumption of the surrounding buildings. The proposed concept is that the heat from the pavem...

Urban climates and heat islands: albedo, evapotranspiration, and anthropogenic heat

As an introduction to this special issue on urban heat islands and cool communities, this paper reviews some of the characteristics of urban climates and the causes and effects of urban heat islands. In particular, the impacts of surface albedo, evapotranspiration, and anthropogenic heating on the near-surface climate are discussed. Numerical simulations and field measurements indicate that inc...

Semi-automatic Parking System Recognizing Parking Lot Markings

This paper describes a semi-automatic parking system, which can designate target position by recognizing parking lot markings. Driver is able to designate or refine the target position by drag&drop based novel user interface. Peak pair detection and clustering in Hough space recognize marking lines. Specially, one-dimensional filter in Hough space is developed to incorporate a priori knowledge ...
