Research on GIS-Based Urban Road Network Congestion Recognition Model

Estimating Urban Road Congestion Costs

Economists wishing to analyse road congestion and road pricing have usually relied on linkbased speed-flow relationships. These may provide a poor description of urban congestion, which mainly arises from delays at intersections. Using the simulation model SATURN, we investigate the second-best proportional traffic reduction and find that linear speed-flow relations describe network flows quite...

mortality forecasting based on lee-carter model

over the past decades a number of approaches have been applied for forecasting mortality. in 1992, a new method for long-run forecast of the level and age pattern of mortality was published by lee and carter. this method was welcomed by many authors so it was extended through a wider class of generalized, parametric and nonlinear model. this model represents one of the most influential recent d...

Research on Urban Road Congestion Pricing Strategy Considering Carbon Dioxide Emissions

Congestion pricing strategy has been recognized as an effective countermeasure in the practical field of urban traffic congestion mitigation. In this paper, a bi-level programming model considering carbon dioxide emission is proposed to mitigate traffic congestion and reduce carbon dioxide emissions. The objective function of the upper level model is to minimize the sum of travel costs and the ...

Automatic Road Network Recognition and Extraction for Urban Planning

The uses of road map in daily activities are numerous but it is a hassle to construct and update a road map whenever there are changes. In Universiti Malaysia Sarawak, research on Automatic Road Extraction (ARE) was explored to solve the difficulties in updating road map. The research started with using Satellite Image (SI), or in short, the ARE-SI project. A Hybrid Simple Colour Space Segmenta...
