An Optimal Parking Space Allocation on Unoccupied Space for Addis Ababa City by Using AHP Model

Abstract

A shortage of parking lots and allocation problems in cities leads the drivers to search parking area for a long time, create traffic congestion, long-distance walking to the final destination, increase fuel consumption, and also increase emission into the environments. Due to this, the objective of the study was to allocate new parking areas on unoccupied free space and to prioritize the selection criteria of parking location using AHP model. The study was collecting the data through using two data collection methods through quantitative and qualitative. The qualitative method included interviews and questionnaires. As a result of research, the newly allocated parking location in the unoccupied area was Yetekatelewu area. Those selection criteria were ranked with various experts and their judgments' were evaluated with the AHP model and prioritized as the following, Future of land purpose (31%), location of a parking area (30%), land-size (20%), future demand of parking area (8%), land-cost (7%) and environmental effect (4%) are respectively. And also finally, checking the consistency of the newly allocated location through sensitivity analysis is 0.003. As the result, it’s not perfect or consistent. But, the acceptance level is 0.0024 which is an acceptable parking location.
