1 St. Louis District Mobility July/August 2015 GuidePost Freeway Mobility was impacted in July but improved in August As Construction and Pavement repairs on Eastbound I-44 at I- 270 completed Choke points still exist in AM on EB I-70 At I-270, NB I-270 from I- 55 to Clayton Road, WB I-64 Kingshighway to McCausland Continued Evening rush problems exist EB I-270 at Lindbergh and I- 170, WB I-70 at I-64 and I-64 in Both directions downtown, mid- Town and west of the I-270 corridor Arterial Mobility remains consistent with slowed travel near interstates in the AM and the PM peak is slower overall TTI Urban mobility Report ranked St. Louis 65 th with a Travel time index of 1.16 see full 2015 Urban Mobility Scorecard and Appendices Urban Mobility The MoDOT Traffic Management Plan for the renovation of the driving surface on the I-270 bridges over New Florissant Road and New Halls Ferry Road worked much better than Anticipated with only moderate impacts.

The vehicle slid down grass embankment traveled thru the guardrail and ended up in lane 1. The guardrail was knocked into the southbound lanes of I-270. A tractor trailer swerved to miss the guardrail and jackknifed. The tractor trailer went under the Dougherty Ferry overpass striking the rock wall and piers, causing debris to block the lanes. The truck split and could not be towed prior to start of rush hour. Action: Motorist Assist provided traffic control and the bridge was inspected for structural damage with none noted. Traffic initially diverted off at Dougherty Ferry with no queue. EOC and Motor Carriers were notified of the closure. Lanes were progressively opened for morning rush and the tractor trailer remained on shoulder until am rush was over.

Driver of first vehicle was fatally injured. The 2 passengers from second vehicle were ejected one off the bridge, resulting in two more fatalities. Closure resulted in a 1 mile queue for two hours and seven minutes. Action: Special Ops provided traffic control; MSHP Reconstruction and water rescue were called to scene. EOC, Communications, AE and Motor /Carriers were also notified.

9 Incident Management Major Impact Traffic Incidents and Mitigation 7/15/2015 (Wednesday) Time: 5:08 am 3:52 pm Location: Jefferson County Southbound I-55 before McNutt Road Event: Overturned Tractor Trailer Estimated Initial Impact: Rush Hour: 2 of 2 travel lanes affected equals (=) 100% Incident Detail: A tractor trailer ran off the roadway and overturned, splitting open the trailer loaded with packaged cereal grain. Three separate tow vehicles were required to remove the tractor and trailer. Traffic was diverted from I-55 at Route Z to US 61 Southbound returning to I- 55 at MM 176. Traffic queued to Route M (4.5 miles) resulting in a major disruption of mobility. During the removal, the roadway was damaged and resulted in Maintenance replacing a large piece of pavement before the roadway could be totally open. Maintenance setup a lane drop in the right lane for repairs of the roadway and guardrail. Clean up of the spilled cereal grain occurred simultaneous. During the lane drop the queue was ¾ of a mile back to Route Z. Action: Motorist Assist and Maintenance responded for incident management, roadway repairs and traffic control. The on-call signal engineer was notified and made signal adjustments along the diversion route. MoDOT Communications, AE, EOC and Motor Carriers were notified of closure and detour route.

For example, data is generated from detectors on I-44 east of MO 141 (previously included all available in the District). All baseline data for 2014 was recalculated with the revised detectors on routes as shown above. 29

34 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 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 34

35 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. Worst Time to Travel Clocks - The clocks found on the speed charts depict the progression of travel speeds during the commute peak period at the worst congestion location along the route. - For example, the clock on the left depicts conditions worsening at a particular location beginning at 6:30 a.m. with the slowest speeds between 7 a.m. and 8:15 a.m. Conditions improved at 8:45 a.m. Definitions ACTRA Traffic signal management software program Alert message sent regarding an incident or event on the roadway Arterial Missouri State Highway Numbered Routes, not fully access controlled Arterial Device ITS equipment located along MoDOT arterials DMS - Dynamic Message Signs along highway displaying incident and travel time information Defined Sensor A single sensor with an individual ID focused on a particular roadway; defined sensors may be located at one physical sensor location Driver messaging Messages placed on DMS boards to alert drivers of incidents ahead of their direction of travel EOC Emergency Operations Center operated by MoDOT in Jefferson City ER MoDOT s Emergency Response units that provide emergency assistance during nights and weekends typically not covered by Motorist Assist units multiple 35
