Three transportation projects have been proposed to increase the safety in and around a residential neighborhood. Each project consists of upgrading existing street signing to highly retro reflective sheeting to

Assume that the discount rate is 10 percent. Calculate the present worth for each alternative and determine the preferred project based on the economic criteria.13-12
