- Multi-Variable Traffic Control: Simulating the Impact of Weather and Incidents via Type-1 Fuzzy Logic (2026) · International Journal of Research in Engineering Science and Management · doi
Conventional traffic control systems often disregard external factors such as weather and incidents. Existing fuzzy logic intersection control systems have limitations, such as not incorporating multiple variables. There is a need for a novel approach to traffic control that can adaptively adjust signal timings to compensate for reduced roadway capacity and longer stopping distances.

The traditional fixed-time traffic light systems are less effective due to the increase in the number of vehicles. The traditional traffic control systems are based on set time cycles with no Feedback and are very limited in their capability to manage variable and hardly predictable situations of road traffic.

Conventional traffic signal systems operate using fixed time intervals without considering real-time traffic density, resulting in unnecessary waiting time and environmental pollution. There is a need for a cost-effective and reliable system that can dynamically adjust traffic signal timing according to traffic conditions.
