Prediction Modelling Of Road Crash Frequency A Review And Assessment On Different Approaches

Crash prediction version has often been utilized in dual carriageway protection studies. It may be utilized in figuring out foremost contributing elements or set up dating among crashes and explanatory twist of fate variables. Crash frequency refers back to the prediction of the range of crashes that might arise on a particular street section or intersection in a given time period. On the opposite hand predicted crash frequency is an anticipated street site visitors crashes which can be calculated the use of a calibrated SPF (Safety Performance Function) and weighted with the found crash frequency using Empirical Bayes (EB) method.rnThe objective of this report is to review and make an assessment on the road crash prediction models done previously, to identify which variables have a significant effect on crash prediction modeling and the methods employed in modeling of highway crash frequency, which can be used as a base line for future researches. Five articles with different modeling approaches, parameters and methods have been reviewed here.rnThe first study was “A Parametric Model for Accident Prediction along Ado Ekiti-Ikole Ekiti Road, Ekiti State, Nigeria” by Olumuyiwa S.Aderinola. “Statistical Model of Road Traffic Crashes Data in Anambra State, Nigeria was the second reviewed paper in this study by Nwankwo Chike H. and Nwaigwe Godwin I.The third study was “Accident Prediction Models for Two-Lane Rural Highways “by K.R.Kalokota. The fourth study was “An Artificial Neural Network Model for Road Accident Prediction: Case Study of a Developing Country” by F.N. Ogwueleka et al. The fifth study was “Development of Models for Crash Prediction and Collision Estimation-A case Study for Hyderabad City” by V.Niveditha, A. Ramesh and M. Kumar.rnAt the end of this study,AADT,85th percentile spot speed, length of road segments, number of lanes, surface condition of road, number of road access and number of road access controls, environmental and traffic characteristics were the main road traffic crash contributing factors considered in most researcher.
