Transportation Technical Committee

Meeting Report
Date: December 29, 1999
Location: Bellevue Hall, New Castle County, Delaware

INTRODUCTION/ OPENING COMMENTS:

Jim Lisa of DEDO welcomed the attendees and stated that this evenings agenda would consist of:

1. Following up on the Broom Street modeling

2. Answering questions that were raised last week concerning Broom Street and Augustine Cut-Off.

PRESENTATION

Joe Wutka, the Chair of the Transportation Committee explained that there was a perception that the meetings are coming to a halt after January 5, 2000 with no coordination of the project following that date. Joe Wutka assured the committee that this portion or phase of the project was nearing an end however, there is still a huge amount of details needed to be worked through. The process will continue through the design and physical construction of the project.

The Department of Transportation will need to hold a public hearing on the project where the general public will be able to provide their input on the proposed road improvements.

Joe Wutka indicated that the drawings that have been shown to this point were conceptual and that detailed drawings and plans will need to be completed.

John Rautzahn of MTA noted that the topics for the evening would focus on:

Augustine Cut-Off:

  • Traffic Distribution as it relates to Augustine Cut-Off;
  • Safety Issues with Partial Signal Option;
  • Capacity Analysis of the Partial Signal Option;
  • The CORESIM Model of the Partial Signal Option expanded to Broom Street and Concord, 18th and Broom, and Alapocas and Augustine Cut-Off

Augustine Cut-Off Options previously discussed were:

  • No change from the existing conditions. Movements as they exist today show severe degradation at all the moves in the year 2010.
  • Right-in Right-out. The traffic congestion on Route 202 would prevent the right turn movement from Augustine Cut-Off in the year 2010.
  • Full relocation of Augustine Cut-Off to the Local Road System. This option did create some diversion onto Broom Street.
  • Partial Traffic Signal Option. Allow right turns out of Augustine Cut-Off to Southbound Route 202 and left turns into Augustine Cut-Off from Northbound Route 202 by signal control. Allowing these movements account for the trips previously diverted to Broom Street.

Safety Factors considered at Augustine Cut-Off:

  • High traffic volumes on Route 202;
  • Signalized intersection near the approach to an Interstate ramp;
  • The weave problem southbound from Foulk Road to I-95;
  • Tie-in northbound from I-95 weave.

The two remaining options at Augustine Cut-Off are the following:

Full relocation to the local road system option:

  • Advantages: fully relocated access to the local road system provides no traffic signals, no delays, no weaves Southbound from Foulk Road to Augustine Cut-Off.
  • Disadvantages: no traffic signals tend to increase driver speed, and additional diverted routes for some movements.

The partial signal option:

  • Advantages of partial signal at Augustine Cut-Off reduces speed, no weave southbound from Foulk Road, the direct routes are available for all movements, no traffic diverted to City Streets.
  • Disadvantages: Safety improvements are not as great as no signal.

The capacity analysis provided indicates the partial signal at Augustine Cut-Off meets the No-Degradation Criteria.

The CORSIM traffic simulation of Broom Street and 18th Street shows the intersection does work at an acceptable level of service today.

Option 5 (Bow-tie) with Partial Signal at Augustine Cut-Off shows all intersections working.

The various traffic movements of Options 5 and Option 6 were reviewed. Both options included no access and partial access at Augustine Cut-off.

John Rautzahn announced and reviewed the Evaluation Survey that was sent to the Committee Members on December 29, 1999. The packet includes instructions to complete the evaluation survey as well as a sheet for additional comments. The surveys should be returned as quickly as possible. The forms may be returned in the self-addressed envelopes, faxed to McCormick, Taylor & Associates, Inc. Attention: Dorothy Daly, or if needed the evaluation may be brought to the meeting on January 5, 2000. The return date of December 31, 1999 shown on the form was incorrect. The date should be January 4, 2000.

Honorable Robert Valihura, Jr. presented a Resolution to the Committee for the renaming of I-95 to

I-195 and for I-495 to I-95. The Resolution will be considered at the January 5, 2000 Transportation Technical Committee Meeting. It was noted that if the Resolution met consensus, the Resolution should be a considered as part of the Committee's recommendation.

Honorable Robert Weiner concurred with the renaming of I-95 and I-495. Mr. Weiner also commented on the Federal Clean Air Act and that the MPO was near its optimal level.

QUESTIONS/ANSWERS/COMMENTS

Q. Will the signal at relocated Route 141 and the Augustine Cut-Off to relocated Route 141 park connector be a 2-phase signal?

A. The signal at this intersection will be multi-phased.

Q. In Option 6 (Diamond), why is the left-turn movement required at Independence Mall? Why can't this movement be completed at Murphy Road?

A. This is one way to provide access for northbound Route 202 traffic to Foulk Road east and Route 141West.

Q. When was the right turn movement at Independence Mall to Foulk Road added?

A. The movement has always been on the Diamond Plan. However, this movement is not required to make the Diamond Option work.

Q. What will the existing Route 141 and the Relocated Route 141 be called.

A. The nomenclature will have to be changed, however, there have not been names given at this particular time.

Q. There appears to be a potential problem area at Augustine Cut-Off with the partial signal option for the right-out backs up and does not allow the northbound movement to make the left-turn onto the relocated portion. The left-turn movement from Route 202 Northbound to Augustine Cut-Off could also create a problem if the stacking length is not sufficient.

A. This intersection must be designed to accommodate these concerns.

Comment from a member of the Transportation Committee: The only reason Option 5 & 6 are on the table is because these are the only Options that achieve no degradation by 2010.

How does the model assign where traffic goes?

A. The model anticipates the driver's behavior. A driver will take the easiest way to get somewhere not necessarily the shortest. The computer anticipates these moves and applies the logic to the model output. The Origin and Destination (O&D) Study completed this past summer was used in the model.

How do we know we are on the mailing list?

A. If you're not sure you're on the list see Michelle Reardon standing at the back doorway.

Comment from member of the Transportation Committee: The distances are not that far from Augustine north to the relocated, Route 141 perhaps a quarter of a mile. It doesn't take that long. You're not walking. People will start going in directions so they don't have to wait. They like to move.

Q. Is the partial signal on Augustine Cut-Off compatible with both Option 5 And Option 6?

A. No, Option 5 (the bow-tie) makes it impractical to have a partial signal because there is no signal on Foulk Road.

Comment from member of the Transportation Committee: There are 70 accidents a year in and around Augustine Cut-Off. This is unacceptable. We now have a chance and an opportunity to do something about this intersection. We know the only real option is to eliminate the Augustine Cut-Off / U.S. 202 intersection. Let's make the right choice here.

Comment from member of the Transportation Committee: The City has gone to the grid system and since that time traffic seems to be moving more effectively. People are given multiple choices.

Which option keeps the optimum traffic moving?

A. The issue that is being addressed by this project is that by the year 2010 we are not degrading the system. Either Option 5 or Option 6 will do that.

Q. Did the Origin &Destination completed in August consider the impacts of the school traffic?

A. Yes, traffic data was gathered at various times of the year.

Were all speed limits in the model observed?

A. The model observed all posted speed limits.

Q. If there are no lights on Concord Pike, will there be an increase in accidents due to the increased speed especially near the City?

A. The roads will be posted for speed.

Conclusion/Adjournment: The committee concluded its meeting at 10:00 PM. The next meeting will be on January 5, 2000, at 4:30 PM at the Brandywine High School Cafeteria.
