A case study of traffic volumes based on GIS distance analysis of shortest route data using own SHORTPATH toolbox

Abstrakt

Transport and its associated environmental impacts vary spatially and temporally, making micro-level data analysis essential. This paper presents a case study that analyses shortest-route parameters and visualises the results in ArcGIS Pro. The research focused on the analysis of traffic volumes in user defined distance from an origin, using a new GIS analysis toolbox “SHORTPATH”. This study was part of the project titled “Research of shortest routes in a transport model in terms of their possible use for traffic analyses”. The developed scripts were compiled into the “SHORTPATH” toolbox, enabling efficient analysis by extracting and processing data from a transport model. One of the analyses performed using this toolbox involved the calculation and visualisation of traffic volumes on the transport network. Data on shortest routes include sequences of nodes and segments of the transport network, along with traffic volumes between trip origins and destinations. This data was processed an R software and uploaded onto a created geodatabase. Scripts were then developed in ArcPython to allow the data to be visualised according to different criteria. This study presents an analysis of distance – based traffic volumes and can be used for traffic environmental analysis as cold and warm engine emissions evaluation. The discovery of the use of data on the shortest routes in a GIS toolbox is the main finding presented in this case study. The second finding is the creation of own GIS toolbox called “SHORTPATH”, which enables various types of shortest path data analysis.
