– The Lincoln/W. Main Street Intersection will be replaced this summer as part of the SR 59 Signalization Project
– We have contacted the design firm for the project and asked them to give us a proposal to updated their previous analysis to determine the impacts of adding the all red phase. We could do the work internally, but we would not be able to complete it in a timely manner.
– We also asked the firm to consider other changes to the signal to make the intersection more pedestrian friendly in the proposal, if the addition of a pedestrian only phase impacted the signal detrimentally.
– We contacted ODOT and they agreed that the analysis would be considered eligible for funding with the SR 59 Project (therefore we pay 20%)
Please note the existing intersection is functioning at (for cars) a Level of Service (LOS) of “E” with an average delay of 65.4 sec. The minimum design LOS is “D” with a maximum delay of 55 sec (preferred is “C” with 35 sec of delay). Knowing this I believe the results of the analysis will show a more unacceptable LOS with the addition of the pedestrian only phase.
However, we think the addition of a “Pedestrian Lead” phase may be possible. In this situation, when a pedestrian pushes the walk button the signal will provide a brief phase where all traffic movements will have a red light and the “called” pedestrian movement will get a “walk” signal. This phase will provide for the pedestrian to occupy the crosswalk before the car. The impact to the traveling public for this type of change may be acceptable. We have already included this “Pedestrian Lead” phase for the signals at SR 59/Horning and SR 59/Midway.
In summary….we are working on the request, it will be a few months before we get enough information to make an informed decision, it will cost us a small amount of money that is already budgeted and any changes will be made with the new signal installed this summer.
