The objective of this project is to analyse the profile of the incidents on the expressways in Singapore and focus mainly on the investigation of the response time of the recovery crew. Data of the month July 2008 was obtained from Land Transport Authority. Statistical analysis was being carried out on the data. Comparisons between the mean response time for different situations was done using hypothesis testing. It was found out that the recovery crew took a longer time to reach the site during peak hours compared to non-peak hours. The frequency for the time between incidents is calculated for PIE, CTE and AYE to find out whether there is any pattern between time of occurrence of the incidents. A runs test was being done and it was found out that the occurrences of the incidents are randomly distributed. The different sources of detection of incidents were being analysed. It is found out that the surveillance cameras that were being installed along the expressways were proven to be the most efficient in detecting incidents.
