Abstract: A method and system for controlling the purchase of fine-grained resource purchases, such as utility resources or access to limited highway lanes. Real time pricing based upon current demand and/or usage is periodically determined. Access to that real time pricing information is obtained by individual users via a distributed computing network or radio frequency broadcast system and utilization of those resources is then locally controlled based upon that pricing information. Access to limited highway lanes may be priced based upon current actual utilization and pricing information is then broadcast, permitting users to selectively access those lanes based upon real time pricing decisions by those users.
