Most agencies don't follow a comprehensive traffic management plan. Scientific planning before beginning construction helps in avoiding bottlenecks later.
Roads should be widened wherever possible to compensate for construction. Additional lanes should be opened for traffic on opposite side of where construction is going on.
There should be alternative routes and diversions available for motorists to avoid congested stretches.
Most construction sites lack proper signages. Each agency follows its own standards and there is no uniformity.
Encroachments should be first removed to provide more space for motorists.
Proper enforcement is required. Adequate private traffic marshals should be deployed along with traffic policemen.
There should be proper barricading to separate construction area from road traffic.
Adequate lighting is required at stretches where construction goes on in night.
Construction material and machinery should not be kept in the open.
Motorists should be informed in advance through print advertisements and road signages about road diversions.
