Work Zone Safety & Mobility Rule When the rule was announced a couple years ago, MoDOT went to work right away to develop our policy.

Transportation Management Plan Strategies to manage work zone impacts of a project Temporary Traffic Control Plan For Significant Projects Traffic Operations Public Information The purpose of the TMP in Missouri is to manage the work zone impacts of the project. Every project gets a basic Traffic Control Plan, as they have for years. For Significant Projects (I.e., those projects that have a significant impact on traffic during construction), two additional areas are needed: Traffic Operations strategies Public Information efforts This obviously begs the question: What is a significant project in Missouri? What is a significant project in Missouri?

Initial Criteria (Fall 2007) Significant Project ? A significant project is one that, alone or in combination with other concurrent projects nearby, is anticipated to cause sustained work zone impacts greater than what is considered tolerable based on this policy and/or engineering judgment. Initial Criteria (Fall 2007) Interstate lane closures for 3 days or more Every job on Statewide Transportation Improvement Program (STIP). First, the “official” FHWA definition. We found this a little unhelpful, so we decided to develop our own criteria to guide designers and project managers. MoDOT’s criteria for determining “Significance” have evolved over time. We started with very simple criteria. The first was the FHWA definition in The Rule regarding Interstate work. It deems a project significant if it includes lane closures (constant or intermittent) on an Interstate road for 3 days or more. The second was very simple. Every project on our Statewide Transportation Improvement Program (STIP) was defined as significant. This caused us some problems and put undue work on our designers and project managers. We were requiring Transportation Management Plans (TMP) on very basic projects, or even projects that had little or no effect on traffic safety and mobility. We are currently in the process of developing more specific criteria…

New Criteria (Proposed in 2008) Significant Project ? New Criteria (Proposed in 2008) Interstate lane closures for 3 days or more Full FHWA oversight Major Route in an urban area Capacity values to exceed those in the Work Zone Guidelines. We are currently developing new criteria that will still fulfill the intent of the TMP without putting unnecessary work on our project managers. This is the same federal standard from previously. Any project under full oversight by FHWA will be considered significant. We have our 32,000 roadway system split into Major Roads and Minor Roads. The Major System is about 5,000 miles of the state’s most heavily traveled roads. If we are working in an Urban area on a Major Road, those criteria deem a project significant. Our Work Zone Guidelines give certain capacity thresholds for closing lanes on roads. We have an internal application used by designers and maintenance operations to determine at what time of day they can work on each route on our system. If a project will cause these values to be exceeded (by closing lanes at certain times on certain routes), a TMP will be necessary. We also included a couple special situations where we do not require TMPs. The first is a mobile operation, be it maintenance pot hole patching, contract striping, etc. We still communicate with the public about where these work zones will be, and the field personnel are careful about when and where they occur – but they do not require a TMP. And for any project that does not affect traffic on the state route, a TMP is not necessary. Not Significant Mobile Operations State route traffic not affected

How do we choose strategies? Choosing Strategies Traffic Operations Mitigate impacts on mobility Public Information Affected road users General public Area residents/businesses Public entities As many of you know, the basic pieces of a TMP are a Traffic Operations component and a Public Information component. FHWA produced a very large appendix with strategies project managers could read through. We were concerned about how it would be utilized (or not used at all) by our Design staff in the districts. In order to increase the likelihood of usage, we developed a software tool to assist. It’s simply called the Strategy Matrix Report. How do we choose strategies?

Strategy Matrix It’s a very basic application, and runs on Microsoft Access. After inputting basic information into this screen, the user is led to a series of input screens (next slide)…

Strategy Matrix … that ask the user to input the aspects of his/her project. The tabs match the FHWA Strategy Matrix: Duration/Staging, Impacts, Location, and Traffic. Based on these inputs, the program will spit out appropriate strategies to consider for that job (next slide)…

Strategy Matrix Along with each strategy comes Pros and Cons to help the project manager make a decision on that strategy. It’s main purpose is to make the list shorter for the PM to look through.
