Freeway Management Readings from every detector on the interstates in the St. Louis District are used for this comparison. An average 24 hour volume value is determined for each route and direction per month. The average values are then combined for a total 24 hour volume. The values presented represent the number of vehicles on the district s interstates on the average weekday for each month. 15
Arterial Management New Arterial Travel Time Index This is the fifth month attempting to report arterial travel times in a similar format to freeways. Data from MO Route 141 and US Route 67 are presented for in both the AM/PM peak for North and Southbound directions. An explanation of how this effort is being completed is included in the following paragraphs. Arterial mobility is measured by a travel time index, or TTI. The TTI for a segment of roadway over a peak period is calculated by dividing the average travel time by the expected travel time. The expected travel time is simply the length of the segment divided by the posted speed limit. Due to signalization of arterials, determining a true free flow speed is not practical. For this reason, the posted speed limit is used rather than the free flow speed. A value greater than 1.0 means the average travel time during the peak period is longer than the expected. Because arterial travel times are measured over a segment rather than at a point, the TTI charts display one index value for the entire segment. This means the TTI will be displayed as a straight line between measurement points rather than as a slope from one line to the next as shown on the freeway charts. The travel time indices being presented are the current month and the previous month. A comparison of the previous year will be added as soon as the information is available for analysis. Arterial mobility on MO Route 141 was introduced first, with US Route 67 the second of several instrumented arterial routes to be added in the future. Eventually, as more routes are added to the report, the arterial travel time index will be displayed on a color coded map similar to the freeway mobility map. MO Route 141 US Route 67 16

Arterial Management 7/1 (Tuesday) Location: Southbound I-170 ramp to Westbound MO 180 Event: Vehicle drove off of road into tree and shut ramp down Time: 8:55 am 10:17 am Total Time: 1 hour 22 minutes Action: Signal at MO 180 @ I-170 was set to free to flush the traffic through. After the truck was removed from the ditch, signal was set back to normal operation Result: The adjustment moved traffic efficiently with no backups on either approach. Vehicles were making illegal right turns from left turn lanes (but yielding to opposing left turn movement). 21
Arterial Management Fair St. Louis Events The City of St. Louis, St. Louis Metro Police Department, MoDOT, Forest Park Forever, Fair St. Louis and Metro personnel met for several months to prepare for the July Fair St. Louis Events in Forest Park. The group worked on a plan to mitigate traffic issues for the event including the interstates, major and minor arterials and parking facilities. The city and MoDOT worked together on coordinating signals along multiple corridors affecting ingress and egress over the three day event. The egress coordination plan was implemented for testing Saturday morning June 28 th at 5:30 a.m. The implementation went well with a few fine-tuning adjustments that needed to be made. A traffic mitigation plan was also implemented that covered the event dates and times from the open of the fair to the closing on July 5 th with the fireworks. Thursday July 3 rd events: The lane drop that was supposed to be on Forest Park Parkway (FPP) was incorrectly set up on Skinker instead of FPP and the responsible traffic control company responded an hour later to correct the lane drop issue. As a result, Skinker northbound traffic became congested and the AM plan (2/4/1) was implemented to relieve congestion. The NB left turns on Kingshighway at Barnes Hospital and West Pine were eliminated at 3:00 p.m. to limit access into the park and to improve traffic progression on the corridor. Planned WB I-64 ramp closures at Hampton and Clayton/Skinker for the event were implemented between 3:30 p.m. and 4:30 p.m., at which time the SB left turn from Skinker to I-64 was eliminated to coincide with the on-ramp closure. The traffic on Kingshighway and Skinker/McCausland was heavy between the hours of 3:30-5:30 p.m., which construed Thursday s PM rush. As the PM rush was winding down, the signals at Kingshighway, Hampton, and Skinker/Clayton were placed on the AM plan (2/4/1) to accommodate access into the park. The signals at Kingshighway, Hampton, and Skinker/Clayton were switched over at 7:00 p.m. for the PM plan (3/4/1) as traffic patterns switched from peak entry into the park to beginning to exit the park. The signals on Lindell were switched over at 7:42 p.m. to the PM plan (3/1/1) (the normal plan was used vs. the egress plan due to the planned lane drop not being deployed on WB I-64). The entry plan for I-44 WB off ramp at Vandeventer was scaled back due to the lack of ramp traffic that was anticipated and the traffic queues on Vandeventer. The fireworks ended at 10:18 p.m. and the exit from the park started. At 10:56 p.m. the signals at Hampton and Skinker were switched to the exit plan (3/2/1) as traffic made it to the park exits to these arterials. Full egress from the park completed at 11:22 p.m. and the egress traffic off of the arterial was done at 11:45 p.m. and AM plan (2/4/1) was implemented for Kingshighway, Hampton, and Skinker/Clayton for Friday s events. 22
Arterial Management Friday July 4 th Events: The command center opened at 08:40 a.m. and all city cameras started the day down due to a power outage at Soldiers Memorial that caused the camera outage. The North/South arterials were already running AM plan (2/4/1). The city camera system was back online and running at 10:00 a.m. The McCausland/Skinker arterial had a large queue exiting from the parade at 12:02 p.m. therefore the arterial was placed on PM plan (3/4/1). The inbound fair rush began at 7:26 p.m. The North/ South arterials were placed on AM plan (2/4/1), which was able to hand the traffic volumes entering the fair. There was a gas main break discovered at 7:38 p.m. on SB Hampton @ West Park where one SB lane was temporarily closed until the work could be postponed until overnight. The McClausland/Skinker arterial was placed on exit plan (3/2/1) due to heavy pedestrian traffic at Forsyth at 9:11 p.m. The Kingshighway, Hampton and Forest Park Parkway arterials were placed on exit plan (3/2/1) between 9:58 & 10:38 p.m. The fireworks show was on from 9:57 p.m. to 10:16 p.m. The Skinker/McClausland arterial egress was completed at 11:15 p.m. After the main park egress, the Hampton arterial was placed on PM plan (3/4/1) to give more time to the NBL onto I-64 and less delay for Oakland since the exiting traffic pattern switched from exiting the park to exiting via Oakland. Full egress was completed at 11:39 p.m. and the North/South arterials were set to the AM plan (2/4/1). Saturday July 5 th Events: The third day of the fair opened to the public at 12:00 p.m., at which time there was a heavy volume of pedestrian traffic using the I-64 @ Hampton interchange, Skinker @ Lindell and Skinker @ Forsyth/Lagoon where adjustments were made to accommodate the influx of pedestrians accessing the park via Metrolink. The volume of traffic increased on the North/South arterials for fair entrance and the AM plan signal timing was handling the traffic. The Kingshighway, Hampton and Forest Park Parkway arterials were placed on exit plan (3/2/1) between 10:00 & 10:40 p.m. The fireworks show was from 10:00 p.m. to 10:21 p.m. The Skinker/McClausland arterial egress was completed at 11:30 p.m.. After the park egress, the Hampton arterial was placed on PM plan (3/4/1) to give more time to the NBL onto I-64 and less delay to Oakland again. Full egress was completed by 11:30 p.m. Conclusion: The communication and cooperation between all agencies was highly effective in correcting glitches and mitigating potential traffic related events during the Fair. The close coordination by all involved helped traffic ingress and egress throughout this period resulting in a very successful holiday event. 23
Data Key Work Zones Whenever additional travel time is reported, this additional time shall be evaluated using this chart and adequate mitigation measures should begin within the parameters of this chart. TMC and field personnel are partners in the mitigation of traffic and notification of additional travel times should trigger the appropriate response from both parties. Chart is designed to be an additional travel time reference to establish parameters for gauging the travel impact through work zones and to provide guidance for taking mitigation actions. Travel times can be collected or reported via Blue Toad technology, field personnel, call reports, ITS, TMC cameras, etc. Major and Moderate impacts trigger an IAR (Immediate Action Required) event. IAR means work zone user and TMC partner together to take immediate actions to reduce or eliminate distress. During an IAR event mitigation procedures can range from increased driver notification up to and including removal of work zone. Additional mitigation procedures may require involvement of administration through use of the work zone resolution ladder. Level of Impact Major (Red) IAR Event SEVERE DISTRESS PRESENT Return of roadway to free flow traffic is Priority #1 Moderate (Yellow) IAR Event CAUTIONARY STAGE: Action required by Field/ TMC to prevent escalation to a major event Additional Travel Time Expected 15 minutes or above TMC and field personnel take all steps possible up to and including removal of lane closure to achieve free flow threshold 10 14 minutes TMC increases driver messaging. Field begins efforts to restore free flow traffic Mitigation Actions Immediate Action Required Supervisory mitigation assistance is required using the St. Louis District Work Zone Resolution Ladder as a tool to restore free flow traffic threshold TMC and field shall reach a consensus on mitigation success within 15 minutes or less. If a consensus cannot be reached, mitigation should be scaled upwards in accordance with the St. Louis District Work Zone Resolution Ladder 24
Data Key Incident Levels Major Impact Traffic Incident Road closure > 2 hours Major traffic incidents are typically traffic incidents involving hazardous materials, fatal traffic crashes involving numerous vehicles, and other natural or man-made disasters. These traffic incidents typically involve closing all or part of a roadway facility for a period exceeding 2 hours. Moderate Impact Traffic Incident Blocked travel lanes/closure 30 min 2 hours Moderate traffic impact incidents typically affect travel lanes for a time period of 30 minutes to 2 hours, and usually require traffic control on the scene to divert road users past the blockage. Full roadway closures might be needed for short periods during traffic incident clearance to allow traffic incident responders to accomplish their tasks. Minor Impact Traffic Incident Lane closures < 30 minutes Minor traffic incidents are typically disabled vehicles and minor crashes that result in lane closures of less than 30 minutes. On-scene responders are typically law enforcement and towing companies, and occasionally highway agency service patrol vehicles.
