Monitor Aggressively, Manage Proactively GuidePost I-270 SB lane addition data on page 18 shows major improvement in PM mobility Freeway mobility improved throughout the region despite a 5.2% increase in volume from this time last year. A drop in volume of 3.8 % from last month may have contributed to improvements in areas with continued low mobility Arterial mobility remains consistent on all routes except continued fluctuations on Route 100 and a PM spike on US 67 NB Winter weather impacted regional mobility on December 5 th, 6 th, 13 th, and 14 th Both lane clearance and incident clearance times increased by over 5 and 7 minutes respectively.

Arterial Mitigation Efforts 12/11/13 Wednesday AM Peak Location: Route 267 and Bayless Ave, St. Louis County Event: Two different crashes occurred on NB I-55 before Virginia Avenue with 2 left lanes shut down creating a 6 mile back up with a 20 minute queue Time: 7:16 am - 8:31 am Total Time: 1 hour 15 minutes Action: Call arrived from a traffic engineer explaining there was a large queue on EB Bayless Avenue approaching Route 267. At 8:38 am the timing plan was changed with 7 seconds added to Bayless Avenue to help clear out the queue. No PTZ was available so controller observations were made to see if Bayless Avenue was gapping out and clearing the queue. At 9:12 am the timing was returned back to normal operation. Result: Lack of PTZ coverage and no on site observations prevented an accurate assessment from being made, but controller information showed more gap outs of Bayless Avenue after the timing was adjusted. 12/12/13 Thursday AM Peak Location: WB I-70 between Zumbehl Road and Cave Springs, St. Charles County Event: 3 vehicle crash in the two right lanes, one roll-over. Large backup on WB I-70 that extended to the west of the Route 94 overpass with a 14 minute queue. Time: 8:05 am 9:51 am Total Time: 1 hour 46 minutes Action: Traffic was exiting at Zumbehl Road and using the outer roads as a diversion to get around the crash. Most of the traffic was turning south onto Zumbehl Road and using the South Outer Road (SOR) as a diversion. The timing plans at the Westbound I-70 Ramp at Zumbehl Road and Eastbound I-70 Ramp at Zumbehl Road were changed to plans favoring traffic from the westbound Ramp to the SOR. Once traffic was back to free flow on Westbound I-70, the controllers were turned back to normal operations. Result: Once the new timing plans were implemented, an immediate improvement was noticed on the Westbound I-70 WB Ramp at Zumbehl Road with only a minor effect to the flow of Zumbehl Road.

Average Rate of Travel on Selected Signalized Routes by Calendar Year Average Travel Time per Mile Arterial Management The purpose of this measure is to determine how well selected arterials across the region are operating during the peak traffic times. As improvements are made, such as signal timing, equipment upgrades, or access management improvements, this measure will show the effects of those efforts and decisions on the arterial system. Travel times are measured on various arterial routes. For most routes, data is collected from driving each route multiple times during the A.M. and P.M. peak periods and timing how long it takes to traverse the route. For Rte. 141 and US 67, the Sensys Travel Time system is utilized to determine the travel times and allows a much more comprehensive collection of data. The travel time is compared to the speed limit and the average minutes per mile are calculated. An average minutes per mile based on a perfect run through the corridor is calculated and used as the baseline for comparison. If the actual average minutes per mile are at the baseline, traffic is moving at the speed limits without any stops. The routes where data was collected include the following: Route 141*, from I-55 to I-64 Route 30, from Route PP to Weber Hill Road Route 100, from Route 340 to Maple Lane US 50, from Union West City Limit to Denmark US 67*, from Route 367 to I-270 * Routes where data was collected using Sensys system.

Route 100, from Route 340 to Maple Lane St. Louis County Travel times continue to fluctuate during the PM period on this corridor due to varying circumstances. WB PM is showing an increase over last month where the EB PM is showing a decrease in travel times. The corridor is in its final optimized configuration upon completion of the plans in May. Number of Signals - 8 Length of system - 4.2 miles Speed Limit is 40 mph Number of Lanes - This is a five lane section with a two way left turn lane.

Number of Signals - 6 Length of system - 6.3 miles Speed Limit varies between 40 mph and 50 mph Number of Lanes - This was just recently upgraded to a five lane section. Weighted AADT for length of segment - 16850 AM peak flow is eastbound. PM peak flow is westbound. No current plans to install Sensys Travel Time system. Final 1/14/2014 3:47 PM 25

US 67, from Route 367 to I-270 St. Louis County Travel times showing some minor changes except for the NB PM direction where travel times have been trending higher and have a significant rise in December. Observations during data collection indicate that the traffic volumes on NB 67 are heavier. Optimization on this system was completed in 2012. ACS Lite activated early February 2013. Manually collected data used this month due to Sensys equipment/system failures. Number of Signals - 19 Length of system - 8.3 miles Speed Limit varies between 40 mph and 45 mph Number of Lanes - This is a five lane section with a two way left turn lane.

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.

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.
