MADISON, Wis. — About 100 Madison Metropolitan School District students will be eligible for free daily bus service after the district identified 10 roads and intersections it considers unusually hazardous for children walking to school. The district has long assessed whether crossings pose a danger to students, but this is the first time it has applied a specific scoring formula to make those designations. The formula considers the number of traffic lanes, average weekday traffic, speed limits and intersection controls. Students who live near locations with high scores can qualify for transportation. Among the designated sites is the intersection of South Gammon Road and Mineral Point Road on Madison’s west side. John Muir Elementary School bus driver Don Newman said he watches for drivers who do not slow down around children, and described seeing motorists run red lights. “If the kids were out here, what would they be doing?” Newman said, referring to drivers passing through the intersection. Other designated areas include locations south of the Beltline between South High Point Road and Research Park Boulevard, the intersection of Pflaum Road and South Stoughton Road, and Milwaukee Street and Swanton Road. Vanessa Cruz, the district’s assistant director of transportation and logistics, said MMSD moves to provide service promptly after identifying a hazardous location. The added bus access offers families an alternative to having students cross roads the district has judged to present unusual risks.
