Modelling accessibility via transportation networks based upon previous experience: a Geographically Weighted Regression approach
نویسندگان
چکیده
1.1 Motivation Much research is currently being undertaken in transportation to create more realistic models of transportation networks that account for the spatial heterogeneity in those transportation networks (Mark and Sadek, 2004), and also the different modes of transport that may be used. Simply assuming that users will travel at the maximum speed limit for a particular class of road fails to model local environment factors which may influence speed of travel. For example, the average speed of traffic on motorways is related to the volume of traffic, which tends to be higher around major conurbations. Real time traffic information is useful for relatively short journeys that are already underway, but given the ephemeral nature of this information, it is less useful for longer term journey planning.

Small Area Estimation Via M- Quantile Geographically Weighted Regression
The effective use of spatial information, that is the geographic locations of population units, in a regression model-based approach to small area estimation is an important practical issue. One approach for incorporating such spatial information in a small area regression model is via Geographically Weighted Regression (GWR). In GWR the relationship between the outcome variable and the covaria...
متن کاملAn Approach of Artificial Neural Networks Modeling Based on Fuzzy Regression for Forecasting Purposes
In this paper, a new approach of modeling for Artificial Neural Networks (ANNs) models based on the concepts of fuzzy regression is proposed. For this purpose, we reformulated ANN model as a fuzzy nonlinear regression model while it has advantages of both fuzzy regression and ANN models. Hence, it can be applied to uncertain, ambiguous, or complex environments due to its flexibility for forecas...

Background and Aim: High concentrations of particulate matter-25 (PM2.5) have been the cause of the unhealthiest days in Tehran, Iran in recent years. This study was conducted with the aim of the spatio-temporal analysis of traffic volume and its relationship with PM2.5 pollutant concentrations in Tehran metropolis, Tehran during 2015-2018, using the Geographic Information System (GIS). Materi...

BACKGROUND Proximity to parks and physical activity sites has been linked to an increase in active behaviors, and positive impacts on health outcomes such as lower rates of cardiovascular disease, diabetes, and obesity. Since populations with a low socio-economic status as well as racial and ethnic minorities tend to experience worse health outcomes in the USA, access to parks and physical acti...
متن کاملComparison of Geographically Weighted Regression and Regression Kriging to Estimate the Spatial Distribution of Aboveground Biomass of Zagros Forests
Aboveground biomass (AGB) of forests is an essential component of the global carbon cycle. Mapping above-ground biomass is important for estimating CO2 emissions, and planning and monitoring of forests and ecosystem productivity. Remote sensing provides wide observations to monitor forest coverage, the Landsat 8 mission provides valuable opportunities for quantifying the distribution of above-g...
