Congestion Management System

Appendix C: Summary of Congested Corridors

Corridor #F1 – Interstate 40 (west segment)

Segment Limits: Watt Road to James White Parkway

1997 Travel Time Study Congestion Identification: Classified as congested from Walker Springs interchange to James White Parkway – Marginal to Serious congestion.

Plans or Projects Currently Underway: Currently under construction between Papermill interchange and I-640 west to widen I-40 to 4 lanes in each direction.

Project to widen between Winston Road and Papermill Drive is scheduled to be let to construction in Fall 2002.

Much of the Regional Transportation Management System (TMS) deployment of ITS technologies will occur along this section of I-40.

Observations from Data Collection and Possible Causes of Congestion:

• The travel time runs were performed during periods of roadway construction on I-40, particularly in the sections between Alcoa Highway and Papermill Drive interchanges. This section of I-40 was driven in the westbound direction during the afternoon peak hour, however it was observed that often the traffic was actually heavier and moving much slower in the eastbound direction at this time period, particularly between the Walker Springs and Papermill interchanges.
• The volume-to-capacity ratio was the major factor for triggering the congestion designation for this route. Travel time is currently only a problem in the section between I-640 and I-275.
• The section of I-40 west of I-640 is prone to congestion problems because of the combination of I-40 and I-75 traffic as together they share the same roadway for approximately 17 miles.
• The current construction projects also reduce capacity in this section with the narrowing of lanes and lack of shoulders.
• The construction project set to begin in Fall 2002 has potential to cause severe congestion if traffic is not adequately managed during construction.
• A significant number of trucks are another factor causing congestion.
• A particular problem is non-recurring congestion due to accidents and other incidents, especially in the construction zones.

Analysis of Appropriate Congestion Mitigation Strategies:

• Once completed, the current and planned construction should provide help to alleviate some of the existing problems, although it will likely be a temporary solution should current traffic growth trends continue.
• The deployment of ITS technologies should help to alleviate non-recurring congestion considerably, chiefly by providing quicker incident detection and response.
• This corridor could significantly benefit by an increase in carpooling/vanpooling.

Summary of Congestion Mitigation Strategies to Implement:

• Strategy 1A – Growth Management: Enforce urban growth boundaries, analyze land use impacts on transportation facilities.
• Strategy 1C – Ridesharing Programs: An increase in the average vehicle occupancy rate should reduce the overall traffic demand on I-40.
• Strategy 1D – Alternative Work Arrangements: Attempt to promote through TPO’s “Smart Trips” initiative.
• Strategy 2F – Construction Management: As previously noted, there will be a major portion of I-40/75 under construction during the next 3 to 4 years. It is critical that traffic management and construction management techniques are used to reduce the amount of impact on traffic. Possible measures include – avoiding lane closures during peak hours, fast-tracking the project by working day and night and providing incentives and disincentives to the contractor based on the amount of time it takes to finish construction.
• Strategy 4A – Incident Management: The Knoxville Regional TMS project should address the need for incident management in this corridor.
• Strategy 4B – Advanced Traffic Management Systems: The TMS will include a traffic management center.
• Strategy 4C – Advanced Traveler Information Systems: The traffic management center proposed with the TMS project will provide information to motorists, both through dynamic message signs and the internet.
• Strategy 5A – Additional Freeway Lanes: The section roughly between the West Hills and Papermill Drive interchanges is programmed for construction in the current Transportation Improvement Program (TIP).
• Strategy 5C – New Roadway Construction: The problem mentioned earlier of combining I-75 traffic with I-40 traffic on the same stretch of roadway could be solved to some degree by the construction of an I-75 bypass route. The Tennessee Department of Transportation (TDOT) is currently in the planning stages for a bypass route that would accomplish the goal of diverting I-75 through traffic away from the city.

 

Corridor #F2 – Interstate 640 (west segment)

Segment Limits: Broadway to I-40 (west)

1997 Travel Time Study Congestion Identification: The section between I-275 and Broadway was identified as Marginally congested.

Plans or Projects Currently Underway: Currently the section between I-275 and Broadway is under construction to improve the Broadway interchange and widen I-640 to 3 lanes in each direction.

Observations from Data Collection and Possible Causes of Congestion:

• The volume-to-capacity ratio performance measure triggered the congestion identification for this route, there was no Travel Time related congestion noted.
• One area that is subject to congestion is the westbound on-ramp to I-40, which is currently under construction. This area will be monitored subsequent to the completion of the construction to determine if the problem persists.
• Peak period traffic surges can cause localized areas of congestion, especially at the previously described location of the I-640 westbound ramp to I-40.

Analysis of Appropriate Congestion Mitigation Strategies:

• Since there were no travel time-related congestion problems identified, this route is probably not in need of major mitigation currently.
• This section will benefit from the reconstruction project between Broadway and I-275 and the installation of ITS devices with the TMS project.

Summary of Congestion Mitigation Strategies to Implement:

• Strategy 1A – Growth Management: Enforce urban growth boundaries, analyze land use impacts on transportation facilities.
• Strategy 1C – Ridesharing Programs
• Strategy 1D – Alternative Work Arrangements: Attempt to promote through TPO’s “Smart Trips” initiative.

Corridor #F3 – Interstate 40 (east segment)

Segment Limits: Rutledge Pike to James White Parkway

1997 Travel Time Study Congestion Identification: Classified as Moderate to Serious congestion between James White Parkway and Broadway.

Plans or Projects Currently Underway: The section of I-40 between I-275 and Cherry Street is being planned for a major reconstruction project, which would involve adding lanes and upgrading interchanges.

Observations from Data Collection and Possible Causes of Congestion:

• The travel time data indicated a congestion problem in the A.M. peak period. This section is also operating at high volume-to-capacity ratios.
• This section of I-40 is a bottleneck because it is 4-lanes while the sections directly to the east and west are 6-lane sections.
• The James White Parkway interchange is a deficient design, with unsafe left-hand on and off ramps from the westbound direction.
• Local traffic using I-40 to get from Broadway to James White Parkway must execute a weave from the right lane to the left lane in a very short distance going westbound.

Analysis of Appropriate Congestion Mitigation Strategies:

• It has long been known that this “downtown” section of I-40 is deficient and plans have been studied for several years on appropriate improvement projects, however, the surrounding historic districts and limited right-of-way make construction challenging.
• One feature of the proposed improvements is a “Fifth Avenue Connector” plan, which will remove some of the local traffic destined to downtown and Broadway from the interstate.
• The Knoxville Regional TMS project will include ITS devices in this section of I-40, and will become particularly useful when construction begins to help manage traffic through the construction zone.

Summary of Congestion Mitigation Strategies to Implement:

• Strategy 1A – Growth Management: Enforce urban growth boundaries, analyze land use impacts on transportation facilities.
• Strategy 1C – Ridesharing Programs

• Knox County is currently studying alternatives to improve the Tazewell Pike/Emory Road intersection, which is currently a 4-way stop.

Observations from Data Collection and Possible Causes of Congestion:

• The intersection of Tazewell Pike and Emory Road is clearly a congested area as evidenced by the travel time data.
• Other particular slow-downs that occurred during travel time data collection were between Old Broadway and Jacksboro Pike, and the section between Briercliff Road and Shannondale Road.
• This roadway has a high volume to capacity ratio due to its two-lane cross section and lack of turn lanes, especially at high volume side streets such as Briercliff Road, Beverly Road, Villa Road and Shannondale Road.

Analysis of Appropriate Congestion Mitigation Strategies:

• The City/TDOT project should help to alleviate problems at the highest traffic locations if implemented, however there are several concerns from residents due to sensitive areas.
• The County should continue to pursue improvements at the Tazewell Pike/Emory Road intersection.
• The aforementioned projects should incorporate design aspects to accommodate pedestrians and bicyclists wherever possible, including bike lanes and sidewalks.
