Slide 2
Why are we here tonight? To talk with you about Idaho 19. To
share what we have learned so far. To hear about your experiences
on ID 19 to help identify future improvements - a mostly rural
roadway that travels nearly 15.3 miles from the Oregon State Line
to Caldwell. Corridor Management Plan
Slide 3
NOW A WORD FROM OUR SPONSOR Funding Challenge: Idahos state and
local transportation agencies need an additional $240 million each
year to meet our increasing transportation needs. Without the
revenue increase, we will not have the funds needed to: Improve
highway safety Maintain or improve highway efficiency Match federal
highway funds Corridor Management Plan
Slide 4
NOW A WORD FROM OUR SPONSOR Funding challenge: Idaho is the 4
th -fastest growing state in the nation. Idahos population is
expected to increase by 35% between 2000 and 2020, nearly twice the
national average growth rate. That means more cars, trucks and
drivers and more demand for better roads and bridges. Corridor
Management Plan
Slide 5
NOW A WORD FROM OUR SPONSOR Funding challenge: State revenue is
not keeping pace: Idahos fuel tax has not increased since 1996.
Statewide vehicle registration fees have not increased since 1997.
Highway construction & maintenance materials costs are soaring.

What is a corridor plan? A near-term (10-year) plan. Analysis
of future travel demand and performance in the corridor. Evaluation
of problems and needs. Identification of corridor improvement
priorities. Our objective is to continue to provide a roadway that
is both safe and efficient. Corridor Management Plan

WHERE ARE W E TODAY? Access Points Per Mile Nationwide and
Statewide Studies Reveal An increase of 1020 access points per mile
on major arterials increases crash rate by 30%. Idaho Statewide
data indicate that 37% of all crashes occur at intersections,
driveways and alleys. Well managed arterials have 40% - 50% fewer
crashes. Corridor Management Plan

Why is Access Management Important to Idaho Transportation
Department? Our Mission: Your mobility. To maintain a efficient
high speed linkages from Activity Centers in Canyon & Owyhee
Counties to other places within Idaho. To improve safety remove
unsafe features or add features which will improve both safety and
functionality of Idaho 19. Both of these can be more affordable
with careful access management. Corridor Management Plan
Slide 23
WHERE WILL WE BE TOMORROW? Why is Access Management Important
to ID 19 Users? Improve safety. Maintain a functional highway
efficiently move traffic to and through your communities. Safe and
functional highways is one more reason why the ID 19 travel shed
should continue to be a good place to live and do business.
Planning can help to balance public and private interest. Corridor

Average Rate** Mile Posts: 9.07-14.50 - US 95 to Notus Rd Crash
Rate - 0.70 Below Statewide Average of 1.48 Miles Posts: 14.50-19.9
- Notus Rd to I-84 Business (Cleveland Blvd) Crash Rate - 1.25
Above Statewide Average of 1.18 * Note: Accident rates are average
annual, based on the most recent 5 year period. **Comparison to
Average is based on comparable highways (2 lane widths) serving
rural communities. Corridor Management Plan
Slide 27
WHERE WILL WE BE TOMORROW? Roadway Capacity For most segments
(including three and two lane sections) we are well under capacity
of the roadway today (when we compare current volumes to existing
capacity) but ID 19 users will experience serious decline in level
of service (LOS) after 15 years. Corridor Management Plan

Whats Next BASED ON YOUR FEEDBACK Narrow the list of the needed
improvements. Bring policy and physical improvements to local
stakeholders Task Force for plan review. Take recommended plan
elements to: Local Planning and Zoning Commissions Local Government
