A. 
A priority rating system has been developed to provide a weighted numerical system for prioritizing improvements and maintenance efforts for roadways and rights-of-way currently maintained by the Road/Bridge Department. A similar system will be used for roadways not maintained by the Road/Bridge Department for the purposes of upgrading the County standards and tax billing for improvements, etc. Priorities for roadways maintained by the County will not be intermingled with priorities for roads not maintained by the County.
B. 
Road maintenance and improvements will be evaluated using the following factors and formula:
PI — Priority Index =
TF — Traffic Factor
FC — Functional Classification of Roadway
TR — School Bus Route
MF — Maintenance Factor
AF — Alignment Factor
MI — Miscellaneous/other considerations
PI=TF+FC+TR+MF+AF+[+MI]
C. 
Traffic Factor (TF). The traffic factor will be a measure of current average daily traffic as determined by the Road/Bridge Department by means of mechanical counts, visual count, or their best estimate based on number of residences, farm or other operations, and department staff experience with similar type roads that have had actual counts performed. The traffic factor will be weighted as follows:
ADT
TF

350 — 999

200 — 349
5
100 — 199

D. 
Functional Classification (FC). The functional classification indicates the character of use and purpose of the roadway and is an indicator of the relative importance of a roadway to the overall transportation network. The functional classification will be weighted as follows:
Function
Classification
FC
Type I
Arterial

Type IV

E. 
School Bus Route (TR). School bus routes are an obvious concern for prioritizing maintenance and improvements for safety reasons. The school bus route factor will be weighted as follows:
School Bus Route
TR
YES
2
NO
0
F. 
Maintenance Factor (MF). Roads having high deferred maintenance costs must have a higher priority for repairs and improvements, while roads with low deferred maintenance costs may have a lower priority for repairs and improvements. An example would be a concrete street that needs some preventative maintenance that would be relatively inexpensive at this time compared to a very high replacement cost if the preventative maintenance is not performed. The maintenance factor will be weighted as follows:
Deferred Maintenance Cost
MF
High
5
Moderately High

3
Moderately Low

No Deferred Cost

G. 
Alignment Factor (AL). The alignment factor takes into account the geometric problems of the roadway; vertical and horizontal geometric (sight distance), road width, road grades, etc. The alignment factor will be weighted as follows:
Sight Distance
AF
250'

H. 
Miscellaneous — Other Considerations (MI). The danger of using a mathematical calculation for establishing priorities is that they will be taken too literally. Therefore, other considerations may be taken into account in establishing priorities.
I. 
Many times situations arise that do not fit the parameters as outlined above. Significant cost savings may occur when an adjacent lower priority project is combined with a high priority project. Accident histories as provided by the Missouri Highway Patrol and Cass County Sheriff's office may dictate some adjustments to the priorities. It is also desirable to balance the distribution of improvements geographically within the County. Budgetary restraints may not allow for the highest priority projects to be completed but may allow for two (2) or three (3) lower priority projects. For this reason the Road/Bridge Department and/or County Commission may be required to adjust the priorities by this miscellaneous factor.
NOTE: Roads that end on both ends of a State route or County paved road, add a number of three (3) to the formula. Roads that are within one (1) mile of a City limit, add a number of two (2) to the formula. Roads that are a dead-end to have a number of minus two (-2) to the formula.

Dust control measures will be taken on gravel surfaced roadways to promote safe vehicular traffic flow and to improve site distances. Prioritization will be based on the average daily traffic counts taken by the Road/Bridge Department. The department recognizes that different types of traffic (i.e., truck traffic vs. passenger vehicles) generate different levels of dust. Until more exact methods of counting these different types of traffic are available to the County, any preferences shown would be very subjective. No dust control products other than those approved by the Road and Bridge Department may be placed on the roadways without the express written consent of the department.
NOTE: Dust oil is not permitted for dust control. This is due to future maintenance problems associated with dust-oiled roadway surfaces.

A. 
The County cannot justify placing dust control on all County roadways for traffic safety but recognizes that many residents, given the topography or location of their home in relation to the road, may desire some relief from road-generated dust. Roadways that have been treated for dust control have different maintenance requirements and it will be necessary therefore for the Road/Bridge Department to coordinate any dust control applications for private citizens.
B. 
Approximate cost of dust control chemical application can be obtained from the Road/Bridge Department office (380-8360) in April of each year. A preliminary cost estimate for a once per year application varies from year to year, with an application width of twenty-four (24) inches. The recommended minimum length of roadway to be treated at citizens' expense is three hundred (300) feet. Citizens wishing to pay for the application of dust control chemicals on their roadways must contract with a County approved private applicator.

A. 
A priority rating system has likewise been developed to provide a weighted numerical system for prioritizing brush cutting and vegetation control efforts for road right-of-way currently maintained by the Road/Bridge Department.
B. 
Brush control and vegetation maintenance will be evaluated using factors similar to those used for other roadway maintenance and improvements.
BI — Brush Index
TF — Traffic Factor
TR — School Bus Route
AF — Alignment Factor
BI=TF+TR+AF

The alignment factor is revised slightly for brush/vegetation control to compensate for required road width and height clearance and sight distance. "Sight distance" is defined as the distance from which a person sitting in the driver's seat of a passenger vehicle can see stop signs and other road signs properly placed on the right side of the roadway.
