Identify methods to distribute automated vehicle identification tags to improve market penetration when collecting arterial travel speed information.
San Antonio's experience with automated vehicle identification tags.
Although the system San Antonio deployed never fully met expectations due to insufficient market penetration, the project had technical merit and provided valuable lessons learned that might be useful to other cities considering similar deployments.
- Distribute tags in a way that will reach the most drivers. The project team considered several options for distributing vehicle tags. San Antonio's first choice was to distribute tags through the Department of Motor Vehicles (DMV). These tags would be embedded within the vehicle registration tag and distributed during annual registration. Even though distributing tags in this manner would reach a much larger target of vehicles, DMV was not able to manually distribute the tags only to the county where the project was being implemented. Another vehicle tag technology was chosen and a voluntary program was put in place for distribution. This method resulted in less than 10 percent of vehicle tags being distributed than what was needed to produce adequate results. Technically the system was capable of producing accurate travel times, but it was difficult to provide consistent travel time readings because the low level of market penetration made it difficult to measure travel times consistently throughout the day. A higher concentration of AVI tags would provide more consistent data throughout the day.
- Consider using electronic toll tags if the region has toll roads. San Antonio does not have existing toll roads, therefore they were unable to use existing toll tags. They believe that an area with existing toll facilities would provide a great opportunity to make use of these tags to provide travel time data along arterials. If electronic toll payment is employed in an area, these tags can be used to collect travel times and the costs to implement a travel time system would be reduced.
