Abstract :

The increase in traffic flow necessitates the need to improve the existing roadways and to build additional highways hence creating more work zones. Work zone safety audit help stakeholders to improve safety of workers, drivers and other vulnerable road user in the work zones by finding the potential hazards associated with the construction sites at early stage and proposing both long term and short term counter measures. Assessment of the elements of warning signs, channelizing devices, internal traffic control, work zone configuration, worker safety and road side safety of the work zone studied gives a score of 5.97/10 indicating that the overall effectiveness of the work zone is average. The potential hazards with very high risk level along Kano-Maiduguri road are speeding and aggressive driving, dangerous flagging, misuse of TTCD, non-compliance with signs by the road users, unprotected work area, confusing signs, and use of non-retro-reflective devices. The safety of the work zone can be increased by proper work zone configuration, worker training, regular maintenance of TTCD and increased enforcement.
