School Superintendent Mark Donovan has signed up all of the city’s elementary and middle schools to participate in the city’s Safe Routes to School program. The Metropolitan Area Planning Council awarded Woburn $8,750 in federal funds to initiate the program, which has been offered in cities and towns throughout the country. Participating communities enhance walking routes with the goal of helping to improve the fitness of children by increasing the number who walk or bike to school. The city has been conducting an online survey of parents to find out how children get to school and which of those who now travel by car or bus might be able to walk in the future. Also with the grant, the city will be working with the group Walk Boston to identify the walking routes around schools and how they might be made safer.
