To identify factors associated with RTIs; to identify factors which affect highway capacity in the event of an RTI.
Video recording from CCTV at three road works sites yielded data on 91 RTIs and 539 breakdowns. Police personal injury RTI records were also obtained for two of the sites.Recovery operator’s logsheets (2611no.) were collected from major motorway works sites.Data was collated, coded and analysed.
Shunt type RTIs account for over half the RTIs in the video survey. Loss of control, driver misjudgement and lane changing were also common.
Common contributory factors were: driving too fast for conditions, driving too close, driving aggressively and driving without due care and attention.
Layout features commonly associated RTI locations included: approaches to lane closures, diverging lanes, entry slips and contra-flows.
