摘要：	The analysis of field data overwhelmingly suggests that ramp metering is a cost-effective investment of public funds for the Twin Cities area. This finding notwithstanding, the Twin Cities users of the highway system support the need for modifications toward an efficient but more publicly acceptable operation of ramp meters. The combination of these two factors points towards the adoption of an overriding principle regarding the operation of ramp meters in the Twin Cities: This principle would seek to balance the efficiency of moving as much traffic during the rush hours as possible, consistent with safety concerns and public consensus. In light of this new balance and the need to develop a general policy for optimizing ramp meter operation several steps have been taken since the evaluation data collection was completed. These steps include reduced operating timeframe of ramp meters, allowing meters to change more quickly from red to green, and keeping several meters at flashing yellow.
