At traffic signals, many problems affect people’s health, safety, and comfort. Many drivers do not switch off their vehicle engines while waiting at signals. This causes air pollution and wastes fuel. The smoke from vehicles makes the air unhealthy, especially for people standing nearby., Many drivers also use horns unnecessarily. This creates loud noise, which disturbs other drivers and people in nearby schools, hospitals, and houses. Continuous noise can cause stress and discomfort., During summer, road temperatures go above 40°C. Heat from vehicles and roads makes the surroundings very hot and uncomfortable. It also increases the risk of tyre bursts, which may lead to accidents., Some drivers do not follow basic road safety rules like switching off engines or wearing helmets. This happens because there are no proper reminders at traffic signals., Traffic police also face difficulty because road cones cannot move on their own. They have to lift and place them manually, which takes time and effort, especially in hot weather., These problems show that traffic signals need better systems to reduce pollution, improve safety, and support traffic police.
