India road network is second largest in the world where National highway constitutes 1.5% of total road network. Out of total transportation means, 65% of freight & 80% of passenger traffic are carried by the roads where maintaining this system is crucial for a developing economy like India. Capital requirement of maintenance funds is very large and runs a shortfall of 40% & to address this, a comprehensive system is developed to recommend optimum maintenance actions where road safety audit form a component.
Road Safety Audit is a systematic process for checking the road safety implications of highway improvements and new road schemes. Process is carried out independently of design and construction work intended to ensure that operational road safety experience is applied during the design and construction process.
Audit is carried out in three phases:
Accidents related data, documents assessment, site inspections etc. are carried out throughout the auditing to identify accident black spots, obtain traffic volume count, and site construction practices etc. where safety audit report are proposed for safety recommendations.
The sole objective of the process is to minimize future road accident occurrence and severity once the scheme has been built and the road comes into use.
Advantages of road safety audits are as:
Minimize the risk & severity of accidents on the roads.
Optimize the road as per the need & perceptions of all type of road users.
Ensure construction workers’ health & safety.
Ensure environment safety of work zones
To minimize the risk of accidents on road.
Ensuring safety of vulnerable users like cyclists & pedestrians.
