SimNoise: Simulating the Impact of Noise Annoyance on Intra-urban Residential Migration
Authors of the model: Cécile Tannier and Hélène Houot (ThéMA, University of Franche-Comté, Besançon, France)
Creation date: August 2003
The goal of the SimNoise model is to evaluate the impact of traffic noise on residential location dynamics. It allows the calculation of the probability that the agents living in a given spatial unit will leave this location because of traffic noise.
The mathematical formalisation of the SimNoise model is of a probabilistic nature. The basis for the construction of the model is a survey on annoyance of traffic noise in the French city of Besançon.
Concerning the thematic assumptions of the model, it has been decided to retain only the first order variable describing the noise environment of a road segment, which is the noise exposure level. The second assumption is: for a given noise exposure level, the annoyance and its effect on the mobility of the agents vary with respect to four individual characteristics:
- housing occupancy status (owner or tenant)
- satisfaction with respect to the neighbourhood of residence
- age
- level of the sensitivity to the traffic noise (partly resulting from the previous noise experiences of the agents).
These four variables are considered as being independent. Existing dependencies are taken into account in the course of modelling by mean of mathematical relationships. The distinction of individual variables allows the differentiation of types of agents of homogeneous behaviour, with each type of agents being a unique combination of the modalities of the variables.
If you want to work with the SimNoise model, you can use the SimNoise application.
The SimNoise application has been developed by Gilles Vuidel using the software Matlab.
Instruction for use:
- Copy the directory called SimNoise on your disk.
- Open the file called SimNoise.bat
- Choose the parameters and the aggregation operators that you want.
- Choose the name of the directory in which the results of simulation will be saved. (Such directory is created in the parent directory SimNoise at the end of each simulation).
- Click on the button "Calcule". The results of simulation are automatically saved in the chosen directory. You can open the files with the blocknote and work on it with another software like Microsoft Excel.
