Wis. Admin. Code Department of Transportation § Trans 209.07 - Candidate project identification process
(1) GENERAL
DESCRIPTION. Candidate project identification is accomplished within the
overall framework of developing the highway and bridge improvement program . The
department shall identify both the surface, structure, safety, geometric or
capacity deficiencies, singly or in combination, and the alternative
improvement levels to correct or reduce the deficiencies.
(2) RESPONSIBILITIES. The transportation
region offices, with the guidance from the central office , shall take the lead
role in identifying candidate projects for the resurfacing, reconditioning,
reconstruction, interstate, major and bridge program areas. The regions shall
provide the regional and local viewpoints and knowledge of unique local
conditions to program development.
(3) COLLECT AND DEVELOP DATA. The department
shall maintain a system of uniform data collection for segments of the highway
system. This data shall be used for comparison and evaluation purposes to
assist in determining that the most appropriate and beneficial candidate
projects and improvement levels are selected. This data shall be updated, as
necessary, for the recycling of the program. The following data will be
collected and developed where appropriate:
(a)
Highway data
1. Pavement surface
type
2. Year surfaced
3. Widths: right of way, travel lane,
pavement, shoulders, median, and parking lane
4. Lanes: travel and parking
5. Driveways
6. Posted speed
7. Pavement serviceability index
(PSI)
8. Accident
information
9. Curves with limited
stopping sight distance
10. Steep
grades
11. Percent no passing
zone
12. Average daily
traffic
13. Forecast average daily
traffic
14. Hourly vehicle data and
hourly capacity
15. Parking
restrictions
16. Terrain
17. Access control
18. Maintenance problems
(b) Bridge data
1. Deck condition: expansion and construction
joints
2. Superstructure: main load
carrying members, floor system
3.
Substructure condition: abutments, piers, bents
4. Waterway condition: adequacy of opening,
flooding, debris present
5.
Approaches condition: roadway condition, horizontal and vertical sight
distance
6. Capacity condition:
design, inventory and operating load, posting, maximum vehicle weight, load
rating basis, overburden depth
7.
Field inspection and office appraisal rating
(c) Historically collected environmental,
social and economic data
1. Land use
2. Right-of-way required
3. Housing and business units
required
4. Farms
affected
5. Land required:
agricultural, wetland and upland habitat

(e) Pavement age that is more than 20 years
on portland cement concrete or more than 15 years on bituminous
pavements.
(f) Pavement width that
is less than 21 feet.
(g) Shoulder
width that is less than 4 feet.
(h)
Bridges that have a sufficiency rating less than 50 or have a condition or load
rating of 3 (basically intolerable condition requiring high priority of
repair).
(6) DEVELOP
ALTERNATIVE PROJECT IMPROVEMENT TYPES AND COST ESTIMATES. The department shall
identify a range of practical improvement types for each candidate project. The
range of alternatives for highway projects may include: patching and
maintenance resurfacing (the equivalent of the "no build" option); improvement
resurfacing; minor and major reconditioning; and reconstruction (See Figure 2).
Alternatives for bridges shall be: maintenance; rehabilitation; or replacement.
(a) The department shall consider the
following factors for the range of alternative improvement levels of a given
project:
1. The nature, number and severity
of the deficiencies present;
2. The
overall budget available;
3. The
cost estimate for each alternative;
4. The associated federal-aid eligibility
requirements;
5. The existence of
other related projects;
6. The
probable project effects concerning safety, energy consumption, economic
development and the social and natural environment;
7. The traffic volumes served by the proposed
project .
