Work Zone Rule Virtual Workshop –
Rule State of the Practice Overview
Assessing the State of the Practice
FHWA has identified several ways to assess the state of the practice and effects of the Rule: Review of 2008 Work Zone Self
Assessment (WZSA) results Review of responses to five supplemental
questions added to the 2008 WZSA Discussions with State and local agencies
What have we learned?
Rule has brought about positive changes in practices and more focus on managing work zones, specifically in the following areas: Work Zone Policy Impacts Assessment Significant Project Identification Training TMP Development and Implementation Data Collection and Analysis
2008 WZSA Results
Largest increases were in practices related to Subpart J:
Classifying projects based on impacts (Significant Projects) – 25%
Training law enforcement personnel – 21% Establishing a policy to develop TMPs – 20%
WZSA Rule Supplemental Questions
Supplemental question scoring scheme
The Rule Has Caused Change
The Rule Has NOT Caused Change
Other
The agency has significantly experienced this as a result of the Rule.
The agency has
somewhat experienced this as a result of the Rule
This was already taking place prior to the Rule and has not changed since the Rule was implemented.
This was not taking place
prior to the Rule and is still not occurring.
It is too early to tell if the Rule has caused this to occur (but I might know later).
Work Zone Policy Biggest change - Agencies have pulled together several
disparate policy documents and procedures/guidelines into one WZ policy/guidelines. Some agencies did not have a policy for MOT in work zones and
have now developed one as a result of the Rule.

21 agencies (41%) have reported that as a result of their WZ Policy, they are taking a more consistent approach to planning, designing, and constructing road projects
Work Zone Policy (cont.)
Many agencies mentioned they are now considering WZ impacts earlier in the project development process.
Some agencies have established goals and measures for WZ performance (e.g., queues, delay time) as a result of the Rule.
Impacts Assessment
The agency is seeing enhanced consideration and management of WZ safety and mobility impacts - starting during planning and continuing through project completion

24 agencies (47%) experienced this as a result of the Rule
3 of those agencies cited the Rule as causing a significant change in this area
Impacts Assessment (cont.) While planning and designing road projects, the agency is
expanding planning beyond the project work zone itself to address corridor, network, and regional issues – particularly when congestion is an issue.

Too Early to Tell
19 agencies said the Rule had caused this to occur
17 agencies said the Rule had not caused change because most of those agencies (16) were already doing this
Impacts Assessment (cont.)
Agencies also indicated that they are more often using analytical tools to determine WZ impacts 10 to 15% increase in score each of the past
2 years on the 2 related WZ SA questions: During planning to assess impacts of future
construction/maintenance activities To assess impacts when developing TCPs
Significant Project Identification
Agencies are thinking more about project impacts and are more likely to have a process in place to classify projects based on expected impacts As a result, they are better able to assess and
manage WZ impacts WZ SA shows a 25% increase in score between
2007 and 2008 in this area Several States said that they organize a team
to develop the plan for mitigating the impacts of significant projects
Training
Training has been significantly affected by the Rule 27 agencies (53%) said that as a result of the Rule they
had updated/changed training for their staff (designers, planners, construction staff, etc.) to address broader consideration of WZ impacts and management in the scheduling, design, and implementation of projects 11 of those agencies said they had made significant changes
in training
WZ SA question on law enforcement training saw a 21% increase in score from 2007 to 2008
Training (cont.)
The agency has updated/changed training for its staff (designers, planners, construction staff, etc.) to address broader consideration of work zone impacts and management in the scheduling, design, and implementation of projects.

TMP Development and Implementation
Most agencies (90%) now have a policy for developing TMPs to help manage the WZ impacts of a project WZ SA shows a major score increase (20%)
from 2006 to 2007 and again from 2007 to 2008
Some agencies have developed TMP teams and tools
Use of TMP Strategies
The agency is expanding WZ management beyond traffic safety and control to address mobility through the consideration and use of transportation operations (TO) and public information (PI) strategies.

Data Collection and Analysis
Increasing number of agencies report they are establishing measures and collecting data to track WZ congestion and delay
Likely related to the addition of operational data to data provision when the Rule was updated
Agencies establishing measures to track WZ congestion and delay increased 26% (from 23 to 29 agencies) between the 2007 and 2008 WZ SA, which continued a significant increase of the year before
WZ SA indicates a 21% score increase between 2006 and 2007 and a 15% increase from 2007 to 2008 for the question on collecting data to track WZ congestion and delay
Several agencies have started tracking queues
