Practical Designthe ground rules
• Safety: Every project designed with practicality in mind, must get safer. There is no room for compromise where safety is concerned.
• Communication: There is collaboration in developing every practical solution. Communication among designers, stakeholders, and administration officials is open, tolerant, and frequent.
• Quality: The practical solution must function properly and cannot leave a legacy of maintenance challenges. With Practical Design, quality remains at the forefront.

Practical Designthe model
• A project is structured solely on the basis of its purpose and need, no more and no less.
• Life cycle costs must be considered so the burden is not shifted to maintenance.
• Performance information used to support decision making, i.e. HSM, and HCM. (Design Exceptions)
4606 Projects Completed
12.2 Billion Dollars of Investment
6.0% Under Budget
815 Million Dollars in Savings
Since 2011 reduced work force by 20%, sold 124 facilities and 750 pieces of equipment.
Practical Designthe results:
What Has Occurred in Ten Years?
• Largest drop in traffic-related fatalities of any state in the nation in 2006.
• Fatal crashes dropped below 1000 in 2007 and dropped further in the following years.
MoDOT fell below 800 in 2011 and 766 in 2014.
• 40% decrease in lane departure fatalities since 2005.
Practical Designthe results: safety
• Customer satisfaction with MoDOT is 85%
• 95% of customers believe projects are the right transportation solution
Practical Designthe results: communication
• 89% of the state’s major road pavements are in good condition
•71% of the state’s minor road pavements are in good condition
•7th largest highway system in the nation
•46th in revenue per mile
•80% of bridges are in fair or good condition
