Can the timing of the light on Lebanon at the Dallas Tollway be adjusted? The light last 11 seconds on Lebanon and during rush hour this only allows a couple of cars to get through the light. Going north and south on the tollway it stays green for several minutes.
Thank you

Kim,

Can you please specify what direction you are traveling and whether it is in the morning or evening? If you like you can call me at 972-335-5585 x133. We will verify the operation to make sure there aren't any detection problems.

The signal is timed to favor Dallas Parkway because the predominant traffic flow is going southbound in the morning and northbound in the evening. The signals on Dallas Parkway are synchronized to move traffic north and south.

As other north/south routes are completed in Frisco, I expect that the timing will be able to be adjusted to provide more time for Lebanon, at least in the Dallas Parkway area. When the Legacy extension is completed next May, I think the volume along Dallas Parkway will drop and allow us to provide more time for Lebanon. As it is now, the volume on Dallas Parkway is about four to five times the volume on Lebanon during the peak hour. The current timing reflects those volume conditions. If it were your typical four legged intersection, then more time could also be given to Lebanon. But since it is a diamond interchange, we have to make the two sides work together and the keep the area between the frontage roads from filling up and backing onto the frontage roads.

Another project that will begin in January or February is the extension of the DNT. This will take about two years to complete, but the Lebanon interchange will be completely rebuilt because the DNT is going under Lebanon. The new bridge will be 10-lanes wide versus the existing five lanes right now. The traffic on Dallas Parkway will also decrease because the through traffic on Dallas Parkway will now use the mainlanes along the DNT. When that occurs, the timing will really begin to favor Lebanon instead of Dallas Parkway.

Thanks

Thank you for the reply. I am talking about traveling eastbound on Lebanon in the evening and morning traffic. Thank you again for checking into it.
