If you have high-traffic, high-speed roads where people are crossing by foot, your design has failed. The two places where you encounter unwanted crossings in volume in the US are 1. Streets (for commerce, not travel) that were built too wide, either to accommodate too much vehicle traffic or to accommodate a despotic authority that forces wide streets(probably your local fire department or your state DOT); or 2. Stroads that do nothing well, at great expense. If it has a 45mph speed limit and stop lights, it's probably this.
