SP ATIO- TEM"PORAL ANALYSIS OF MOTOR VEHICLE- H.ELATED ACCIDENTS IN ABUJA NIGERIA

Abstract

In this thesis titled "Spatia temporal analysis of motor vehicle related accidents in Abuja Nigeria" an attempt was made to identify the variables relevant for testing the road traffic accidents in Abuja, analyze the Spatia temporal characteristics of road traffic accidents in Abuja. use GIS to identify the black spot location in FCC and outline the implication of the study for road traffic accident management and policy. The data input comprise both the spatial and attribute data. The spatial data (i.e maps) was scanned, digitized, and georeferenced to UTM with the chosen ground control points to form the geographic street database of Abuja. The attribute data include traffic count and accident record obtained by the author and from FRSC FCT Command between 1999 and 2003. The independent variables are Traffic volume, spatial and land use while the dependent variables arc the number of casualty, cases reported, vehicles involved, causes of accident and types of accident. The data were analysed using the EXEL, SPSS and spatial analysis explaincd in vector presentation in georclational map model of Arc view GIS using coverages, overlays and queries. The trend in accident variable between Monday and Sunday, January to December, across the date~ and hours of each day is similar. HOI was not significant for all variables when dry and rainy season as well as early month and month end was compared. But it is significant for some variable and insignificant for other variables when weekday and weekend, and day and night were compared. The statistics also show that H02, H03, and H04 are significant and rejected. These relates to data on different years (1999-2003), road and junction and district in FCC respectively. The points on point overlay confirm disproportionate effect of land use on accident variable while city outlets are more predisposed to accident variables. The study submits that since most of the accidents in FCT were associated with areas of intense business activities such accidents would be reduced if FRSC should increase their presence at city outlets at night, busies routes on weekdays, adverse weather and month -end respectively. The FRSC should be proactive in accident prevention, responsive to the dynamics of acc ident causative factors and reactive to rescue accident victims. There is nls() need ror FI~SC Police road maintcnance agencies and Hospitals to form a strategic alliance or network in data acquisition and exchange and capacity building and exchange respecti vel y.
