Board, Commission or Committee Recommendation
The Transportation Board met on December 6, 2012. Results from that meeting will be presented at the Council meeting.
On February 7, 2012, staff gave Council a presentation on the NM502 design option for the section of DP Road to Airport Road. At the February 7 meeting, Council passed a motion that directed staff to relay to the New Mexico Department of Transportation (NMDOT) the County’s preference for Option 1. A copy of the February 7 Council Meeting Minutes is provided for reference (Attachment A).

In subsequent meetings with NMDOT, they expressed concerns about the traffic Level of Service (LOS) for the side streets Arroyo Lane and Sombrillo Court and asked for the LOS to be checked. The County’s Traffic Engineer calculated the LOS at the intersection of NM502 with Arroyo Lane and Sombrillo Court. LOS for a STOP controlled intersection is based on the average amount of time/delay a driver has to wait before an adequate gap in the conflicting traffic occurs, allowing the driver to proceed. The following lists the LOS for a two way STOP controlled intersection:

LOS A - Average Delay (Seconds/Vehicle) 0-10
LOS B - Average Delay (Seconds/Vehicle) >10-15
LOS C - Average Delay (Seconds/Vehicle) >15-25
LOS D - Average Delay (Seconds/Vehicle) >25-35
LOS E - Average Delay (Seconds/Vehicle) >35-50
LOS F - Average Delay (Seconds/Vehicle) >50
