511 M essage:
Congestion on north I-15 near Rancho Bernardo Rd. Consider alternate routes
inlcuding Exit at Ted Williams to Pomerado North and re-enter at Pomerado on
ramp.
Notes:
Data along the response plan generated arterial route shows a clear increase in
vehicle flow. This increase in flow, however, shows no negative impact on the
speeds or travel times, as is demonstrated by INRIX data along Ted Williams
Pkwy and Pomerado Rd. Travel time remains relatively consistent to normal
day operations for that route. Reasons behind a lack of improvement in travel
time along the route could be attributed to weather conditions (rain and
thunderstorms) during that time frame. Heavy rainfal began approximately
around 2:30pm which is when the event was generated. Event did not trigger
until 3pm, however, once congestion had accumulated along the I-15 North.
