Major Impact Traffic Incidents and Mitigation

7/7/2014 (Monday)

Time: 8:41 am – 12:16 pm

Location: St. Louis City – Eastbound I-64 before Vandeventer Avenue

Event: Two vehicle crash involving a contractor dump truck that spilled its load

Estimated Initial Impact: A contractor dump truck carrying bricks, lumber and assorted materials overturned during the crash spilling cargo across traffic lanes. 4 of 4 travel lanes affected.

Action: MoDOT Emergency Responders and MoDOT maintenance crews set up a work zone and Motorist Assist and Maintenance crews stabilized the travel lanes. A Bobcat was used to remove spilled cargo and a tow crane used to upright the tractor trailer. St. Louis City Police and EMS responded to the scene assisting with traffic control and treating the two injured. TMC posted incident notifications on highway boards in advance of the incident and posted a notification on the traveler information map. MoDOT’s Work Zone Coordinator was notified along with Community Relations who contacted and informed the media.

Result: All eastbound lanes were closed. Traffic was moving on the right shoulder with a queue to Big Bend Boulevard. Traffic returned to normal flow 12 minutes after the incident cleared.

Event Duration: 3 hours 35 minutes

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.

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.

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).

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 28th 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 5th with the fireworks.

Thursday July 3rd 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.

Friday July 4th 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 5th 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.

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. IAR event can be upgraded or downgraded as conditions change.

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.
