Why Now? Why Now?

• Iowa has been interested in MDSS for several years– 2 Years in Functional Prototype with Federal Highways

• 2002 - 2003

– 3 Years with Pooled Fund Study• 2003 - Present

• MDSS concept has had a chance to mature and spread

• We wanted an MDSS as part of the regular forecast– MDSS recommendations based on same forecast– Could be presented as another forecast tool – We didn’t know what to expect from the PF MDSS

• We didn’t want to wait 3 more years

MDSS ConcernsMDSS Concerns

• MDSS is an emerging technology

• No company we knew of had a fully functional MDSS system– Companies were starting to develop

• MDSS would take time to develop• No previous product to try or evaluate

– Limits the number of bidders– Price

The Phased ApproachThe Phased Approach

• 3 years – 3 sets of requirements– Allow vendors time to develop– Open opportunity for more vendors– Gradual introduction and training for

supervisors• Good or bad?• Less overwhelming• First impression of MDSS - is it useful?• Basic at first and more advanced in future

The phasesThe phases

• Year 1– Non-interactive display showing hourly calculated

road conditions and suggested maintenance actions

• MDSS in simplest form• Forecast in form of graphs and tables• No GIS maps• Uses generic road segment in each county for

calculating maintenance actions• Provides Strategic actions but not good tactical actions• Assumes you do the maintenance action recommended

and then calculates future maintenance actions

The PhasesThe Phases

• Year 2– Interactivity begins

• What-if scenarios– Road treatment– Weather

• Still no data entry of maintenance actions– Assumes you do the maintenance action

• Forecast all snow runs on interstate routes• Ability to change plowing cycle time • Ability to change service levels and apply

different rules of practice

The PhasesThe Phases

• Year 3

– All snow runs

– Begin incorporating past maintenance input

– Alternate chemical selections

– Blowing Snow modeling

– Possible use of Pooled Fund MDSS
