| Summary: | The research was undertaken with the aim of estimating safety at road junctions. Accident prediction models were developed in the form of associative relationships between accident occurrences and roadway characteristics, traffic and operational factors at the junctions. The developed models took account of different driving situations encountered by drivers through classifying the junctions according to X-signalised, T-signalised, X-unsignalised and T-unsignalised junctions. Outputs from the accident prediction models were used for safety estimation by means of the original empirical Bayes(EB)method and a modified empirical Bayes(MEB)method. Procedures for developing accident prediction models and safety estimation methods were established and applied to Singapore road junctions. |
