Pedestrian crossing missing across Walden St at the intersection with Richdale Ave on the north side of the intersection. (The other three pedestrian crossings, two across Richdale Ave on either side of Walden St, and one across Walden St on the south side of the intersection, are present.) This is a particularily popular intersection for commuters walking to Porter Sq. Adding the fourth pedestrian crossing would increase safety of existing crosswalks by preventing vehicles from being parked close to the intersection along Walden St, thereby increasing visibility. It would also make corner store more easily accessible, increasing number of visitors, making the neighborhood livelier and more pleasant. Already existing speed limits, speed limit sign on Walden St approaching the intersection from the north, length of plateau on commuter rail overpass, and already existing all-way stop signs ensure that vehicle operators coming from north can safely yield to pedestrians at proposed crosswalk.
