Thank you for the questions.
Question Number 1.
We are working to improve our response to signal timing changes for workzones along the tollway. Often times the lane closures are for one or two days or for only a matter of hours. For construction projects of such a short duration, it isn't always practical to make timing adjustments. If the closure is to last for three to four days or longer and appears to create a signal timing problem, we work to get changes made. We are working towards building a traffic control communications system that will allow us to be more responsive in making timing changes for short durations.
We are also monitoring the construction of the tollway interchange and will be making timing adjustments as necessary.
When a right-of-way (ROW) permit is requested, we inform the contractor that they cannot begin work along the southbound side of the tollway until 9am. Our ROW inspector and construction inspectors try to watch this. If a contractor is working outside of the allowed times, we require them to shut down.
I agree with your assessment of some of the work zones that are used. This past January we added a ROW inspector that monitors construction within the public ROW. We are also now requiring contractors to submit a traffic control plan before a ROW permit is issued. These plans must conform the Texas Manual of Uniform Traffic Control Devices before they are approved. The problem that we usually find is the workers do not follow the approved plan. When we see a poor workzone, we work with the contractor to improve the situation or we shut them down. If you see an unsafe workzone, please call 972-335-5520 during business hours to report it. If it is after hours, please contact the police department at 972-335-5502.
The same telephone numbers can also be used to report signal timing problems. You can also contact me at 972-335-5580 Ext. 196 to report timing problems.
