Eva: A smart highway system should be installed, one that would monitor areawide traffic patterns and communicate with computers in vehicles or with programmable highway signs to give drivers information about traffic congestion and alternate routes  Such a system, we can infer, would result in improved traffic flow in and around cities that would do more than improve drivers' tempers  it would decrease the considerable loss of money and productivity that now results from traffic congestion
Louis: There are already traffic reports on the radio
It would be less costly to have radio stations that give continual, lengthier traffic reports than to install a smart highway system.
