It measures the intensity of vehicles in each lane and gives a priority green signal to the lane, which has the highest intensity of vehicles and the red signal to every other lane. The self–adaptive traffic signal system is a closed loop control system. The system adjusts the traffic signal parameters according to the intensity of vehicles in respective lanes and improves the efficiency of traffic operation on urban road networks. An autonomous traffic signal system can be an effective measure to alleviate congestion of urban traffic. Please visit this page for help.An infrared sensor based prototype of self–adaptive traffic signal control system has been developed in this paper.

Please note that we are working to use the terms 'imaging spectroscopy' and 'imaging spectrometer data' rather than 'hyperspectral.' This allows us to communicate more clearly with our physics, chemistry, and biology science colleagues.ĭownload HyspIRI Airborne Data Convolved to Landsat Bands (NOTE: Link may not work with IE. Research with AVIRIS data is predominantly focused on understanding processes related to the global environment and climate change. The main objective of the AVIRIS project is to identify, measure, and monitor constituents of the Earth's surface and atmosphere based on molecular absorption and particle scattering signatures.

AVIRIS has flown North America, Europe, portions of South America, and Argentina. The Twin Otter aircraft flies at 4km above ground level at 130km/hr. The ER-2 flies at approximately 20 km above sea level, at about 730 km/hr. AVIRIS has been flown on four aircraft platforms: NASA's ER-2 jet, Twin Otter International's turboprop, Scaled Composites' Proteus, and NASA's WB-57. It is a unique optical sensor that delivers calibrated images of the upwelling spectral radiance in 224 contiguous spectral channels (bands) with wavelengths from 400 to 2500 nanometers. Forest Service and NASA's Jet Propulsion Laboratory in Pasadena, California, are answering some of the urgent questions that follow a huge wildfire: In all the acres of blackened landscape, where are the live trees to provide seed and regrow the forest? Which dead trees could endanger workers rebuilding roads and trails? What habitats have been created for fire-dependent wildlife species?
