If you drive through Davis Square in Somerville during the morning rush, you’ll see waves of pedestrians jaywalking across College Avenue on their way to the subway station. Why don’t they use the crosswalk that’s there? Because the crosswalk is actually dangerous.
Here’s what’s taking place. The crosswalk is a “mid-block” variety about 100 feet from the subway entrance. When the square’s lights turn red during rush hour, a line of cars backs up beyond the crosswalk, so that the crosswalk becomes sandwiched between idling cars. When larger vehicles such as trucks and SUVs sandwich the crosswalk, it’s like walking through a tunnel.
