GIS-based method for assessing city parking pattes Nadav Levy a,b , Itzhak Benenson a,⇑ aDepartment of Geography and Human Environment, Tel Aviv University, Israel b Porter School of Environmental Science, Tel Aviv University, Israel article info Article history: Received 12 April 2014 Revised 17 April 2015 Accepted 16 June 2015 Keywords: Urban parking Parking policy Parking modeling Transportation planning High-resolution GIS ArcGIS application abstract Every car trip ends with a parking search and parking. However, current transportation research still lacks practical tools and methodologies to analyze parking needs and dynamics, which cannot be adequately performed at an aggregate level. This paper presents PARKFIT, a novel algorithm for estimating city parking pattes that is based on a spatially explicit high-resolution view of the inherently heterogeneous urban parking demand and supply. Using high-resolution data obtainable from most municipal GIS, we apply PARKFIT to evaluate the fit between oveight parking demand and parking capacity in the city of Bat Yam, both currently and within the framework of the Bat Yam 2030 transportation master plan. We then analyze PARKFIT’s capabilities and limitations, and supply PARKFIT as a free ArcGIS-based software. 2015 Elsevier Ltd. All rights reserved. 1. The problem of estimating parking capacity in heterogeneous city Parking management is an underdeveloped transportation subject.
