1. A system for improving an accuracy of detecting a road works zone by mitigating sensor occlusion, the system comprising:
a memory configured to store computer-executable instructions; and
at least one processor configured to execute the computer-executable instructions to:
receive, from one or more sensors of one or more user equipment, at least one road works observation associated with a road works object;
determine a first lane and a second lane, wherein the first lane is associated with the one or more user equipment capturing the at least one road works observation and the second lane is associated with the road works object, wherein the determining of the first lane and the second lane comprises one or more map matching techniques based on respective locations of the one or more user equipment and of the road works object;
determine traffic density associated with a region in vicinity of the road works object;
compare the determined traffic density of the region with a predefined threshold;
filter the at least one road works observation associated with the road works object based on the comparison;
detect the road works zone based on the first lane, the second lane and the determined traffic density; and
assign a weight to the at least one road works observation based on the comparison, the first lane, and the second lane,
wherein the weight is proportional to a distance between the first lane and the second lane based on the comparison indicating that the determined traffic density is more than the predefined threshold.
