Organizational Structure Shift
Old Days:
• Traffic modeling was a planning task• Operational analysis was performed by traffic engineers• Design was performed by design engineers
» Disconnect between Planning and Engineering» Disconnect between Traffic and Design» Disconnect between Traffic and Operations» Decision Quality suffered!
![Page 7: Fitting Simulation DOT Business Processes€¦ · network-wide freeway simulation, the “METSIM ... •We need to capture the dynamic relationships between these processes •Conceived](https://reader031.vdocuments.net/reader031/viewer/2022030607/5ad657607f8b9a6d708e074a/html5/thumbnails/7.jpg)

![Page 8: Fitting Simulation DOT Business Processes€¦ · network-wide freeway simulation, the “METSIM ... •We need to capture the dynamic relationships between these processes •Conceived](https://reader031.vdocuments.net/reader031/viewer/2022030607/5ad657607f8b9a6d708e074a/html5/thumbnails/8.jpg)
Now:
• Traffic modeling will be done by traffic engineers
• The Planning Model may perceive a loss relative stature
• The middle step--“project level traffic”-- will be integrated with traffic modeling.
• Traffic analysis & modeling will be integrated with the Operational analysis
• Traffic and Design will need to be more integrated
• Design engineers will need to know a lot more about traffic operations.
• The Organization must become more traffic engineering literate

New Generation Simulation -- Alignment Issues
Organizational Structure: WhereWho Control
May need to be incubated outside of existing structures
Culture:Traffic engineering vs. planning Traffic engineering vs. design Top-down vs. bottom-upA simulation model cannot be “owned”
Processes:Data, GIS, Graphic
Paradigms:FlexibilityModel vs. Open Platform

Making MDOT Simulation Friendly
Data Processes:
• All data from all sources must be put on one platform
• All data must be formatted and stored electronically
• The Michigan Framework
• Traffic data tools developed by the METSIM will have independent utility—e.g., the “BALT”
![Page 11: Fitting Simulation DOT Business Processes€¦ · network-wide freeway simulation, the “METSIM ... •We need to capture the dynamic relationships between these processes •Conceived](https://reader031.vdocuments.net/reader031/viewer/2022030607/5ad657607f8b9a6d708e074a/html5/thumbnails/11.jpg)
Challenge
• Build a system model, incrementally, from the bottom up
• Maintain flexibility
• Minimize Model development costs
• Minimize maintenance costs
![Page 12: Fitting Simulation DOT Business Processes€¦ · network-wide freeway simulation, the “METSIM ... •We need to capture the dynamic relationships between these processes •Conceived](https://reader031.vdocuments.net/reader031/viewer/2022030607/5ad657607f8b9a6d708e074a/html5/thumbnails/12.jpg)
Incremental ApproachAs each baby model is broken off, it is:
• Developed to be uniform with all the other models• Brought up to the new base year
As two or more baby models are combined for the next project:
• Their traffic is updated to the new base year• They are joined and new matrices developed

Work Zone Mobility—New Rules
Effects of new rules for work zone mobility :
• WZ will need to go upstream in the process, » e.g., the early environmental process
• Require more functional integration in the Department» e.g., among design, planning, operations
• Earlier consideration of staging and constructability• On projects involving systemic (interstate) impacts, WZ
mobility will» require a network approach» consider the interactive effects between closures» probably require network simulation
» Organization Process Challenge

Metro Region’s ResponseProcess Improvement
• Requires support from other Stakeholders.
• For example, from Planning
• A shared understanding is needed.
• Dialogue among Stakeholders is the first step

Metro Region’s Response
Network Simulation:• The various projects need to be tested on one platform—
model—since their impact areas overlap• How to build a large network, and re-use it for other projects• How to do this without creating a new bureaucracy parallel to
the Travel Demand bureaucracy• In-house or by consultants?• The goal is to have uniformity of the model across the system• If multiple consultants, will there be too many cooks working
on ‘the model’?

Metro Region’s Approach
• Two years ago, Planning initiated the development of a network-wide freeway simulation, the “METSIM”
• METSIM consisted of the Central Detroit Freeway Network and the I-75 corridor, extending out to Pontiac Michigan.
• The METSIM is now being used to develop work zone mobility plans for three other projects (MOTSIM’s):
• Ambassador Bridge Gateway – Construction• I-94 Rehabilitation – the Engineering Report• I-75 Trade Corridor – the Engineering Report

Project Management– P/PMS Tasks / Flows
• New federal requirements for mega projects
• Construction Staging; Constructability; Work Zone Mobility.
• Unique process requirements for I-94 and I-75
![Page 30: Fitting Simulation DOT Business Processes€¦ · network-wide freeway simulation, the “METSIM ... •We need to capture the dynamic relationships between these processes •Conceived](https://reader031.vdocuments.net/reader031/viewer/2022030607/5ad657607f8b9a6d708e074a/html5/thumbnails/30.jpg)
Project Management Plans (PMP’s)
• New federal requirements: Mega projects will require PMP’s, starting at the Engineering Report Stage, or shortly after the ROD.
• We will need to develop a year by year plan of how the project is to be constructed.
• This presupposes that the Financial Plan is in place at this early stage of Design.
• This will require earlier and better construction staging, constructability, and work zone mobility analysis.

MDOT’s Process---P/PMS
Problem:
•We need to start earlier doing Constructability , Construction Staging (CS), and Work Zone Mobility (WZ)
•On large “system” projects, we will need network simulation to perform these tasks
•We need to capture the dynamic relationships between these processes
•Conceived this way—these are essentially new processes
•MDOT doesn’t have an institutional memory
•Neither do most of the Consultant Teams
![Page 33: Fitting Simulation DOT Business Processes€¦ · network-wide freeway simulation, the “METSIM ... •We need to capture the dynamic relationships between these processes •Conceived](https://reader031.vdocuments.net/reader031/viewer/2022030607/5ad657607f8b9a6d708e074a/html5/thumbnails/33.jpg)
Project Management • Project Management Plan Guidance for Mega Projects (and
over $100 million)
• Effort to build predictability into projects
• Effort to move federal oversight further upstream—before construction
• AASHTO found that the cost variances in large projects is larger in the pre-construction phase than at any other time.
• Improving pre-construction processes and building in predictability can have a huge potential pay-off.
• traffic simulation—construction staging– constructability –work zone mobility processes – can play a key role
