Here is a nice link to a PBS treatise on dangerous pedestrian road crossings which has plenty of relevance to our travials trying to get safe bike lane design in challenging places like Monroe Ave around Pittsford Plaza. During the presentation they mention that the current trend is unsustainable and very bad for the evolving demographics, ie more older people who won't be able to drive and are stuck in their suburban houses locked in by 6&7 lane roads.
I had a discussion a few weeks ago with Rich Perrin, head of Genesee Transportation Council who made the same point. Our current road design strategy of continually adding lanes and moving further away from the city is unsustainable. The federal govenment is only able to fund 40% of the roads and bridges that need repair. That is why we are so appealing to tranportation planners. We represent a solution that is not expensive and essentially puts everyone on a "road diet".
