SPATIAL ANALYSIS OF TRAFFIC CONGESTION OF MONROVIA AND ITS SUBURBS

Abstract

A critical component of the transportation management system (TMS) is to analyse road traffic congestion. Traffic congestion analysis is essential to every developing and developed city. Generally, in urban studies, this analysis is frequently disregarded by TMS. From the literature review, it appears that no GIS-based analysis has been carried out for Monrovia and its suburbs, no plan is available to alleviate the problem of traffic congestion Monrovia and its suburbs, and the road network and its effect on traffic congestion need to analyse Monrovia and its suburbs. Based on this, the geographical examination of traffic congestion in Monrovia and its suburbs has been carried out, since it conveys the character of traffic congestion. Monrovia is the capital of Liberia, which is located in the west of Africa. It serves as the commercial and political capital of Liberia with an approximate population of 1,569,000 in the year 2021. In view of the problem that Monrovia faces with traffic congestion, it was decided to investigate the traffic by using the traffic spatial analysis in conjunction with traffic spatial reliance, and a spatial assortment based on the spatial autocorrelation process, which depicted the Monrovia road network traffic system. Kernel density estimation was also used and the trend surface analysis by using the Moran (I) equation to visualize the traffic parameter in a spatial pattern was used to investigate the traffic. This thesis proposes a traffic congestion-reduction approach for cities and suburbs. The road network of Monrovia and its suburbs, as well as the traffic zone, has been generated by using ArcGIS. The Data Interpolating Variation Analysis Geographic Information System is a site that was used to give obtain the administrative boundary and road mark of Liberia in a shapefile form. Based upon the observation of these results that has been analyse it has been proven using Moran (I) value that s when the moran value is above zero (check I > 0) that means that there is clustered traffic in Monrovia and its suburbs. The study area which is monrovia and suburbs vi has lot of traffic congestion from the law of the Moran. From the backdrop it is proposed that the fifteen junction that has been studied need the construction of overhead bridges in Monrovia, installation of GIS based traffic monitor, creation of alternative routes in Monrovia, and traffic light with CCTV should be installed at every junction of Monrovia that will alleviate the trfaffic congestion problem.
