While walking with my wife and pushing my daughter in a stroller, I was educated on the actual problems of the way our streets are designed. Pushing our stroller enabled me to internalize how I have not been taught, nor would have ever considered, pushing a stroller in my traffic engineering training. I have designed traffic signals, pavement markings and lighting, traffic control plans, and ITS plans in my career, all with the commuter in an automobile as the primary user.
From a Complete Streets perspective, accommodating parents pushing a stroller can create wider walking paths, ramps into businesses (and secured stroller parking), protective signing and striping to cross streets, and other solutions that wheelchair bound users may desire.
From a TSMO perspective, using a stroller to determine the safety of temporary traffic control features during construction may yield safer transition zones, improved line-of-sight, clearer signage, and advanced technologies that improve work zone safety and minimize the risk of incidents from the jobsite or vehicle traffic.
