public transportation

I recently finished a paper on alternative transportation for my Green Politics class. Our city's current policy for designing and implementing dedicated 'bike lanes' in the city is very young. Bike lanes are totally dependent on roads getting resurfaced (repaved), and even then they are only considered to be installed. My solution was to create an ordinance that would use the current research to 'install' new bike lanes on roads that were wider than necessary. This would follow the same principles as the 'repave first' plan because the main cost is simply the extra paint. The alternative requires 'blacking out' all the lanes on the road, repainting lines, etc. which can be very expensive.
