Level of Service (LOS)
LOS Control Delay (seconds/vehicle)
A Exceptionally favorable progression. Most vehicles travel through the
intersection without stopping. Free flow operation.
B Very favorable progression. More vehicles are stopped than LOS A.
C Favorable progression. Individual cycle failures may begin to appear.
Significant number of vehicles stopping, but many will pass through the
intersection without stopping.
D Ineffective progression. Individual cycle failures are noticeable. Many
vehicles stop.
E Unfavorable progression. Individual cycle failures are frequent.
F Poor progression. Most vehicles fail to clear the queue.

Existing Railroad Crossings
Majority of trucks are expected to have an origin or destination within the North Country region
Major freight generators
o Local businesses and retail stores
o Agricultural and timber vendors
o Alcoa aluminum
o Port of Ogdensburg
o Massena rail terminal
NY border crossings – 9.55% of all trucks crossing from Canada to U.S. (inbound)
Most trucks from Massena and Trout River border crossings have NY origin/destination
Alexandria Bay and Champlain border crossings used for transporting goods to other states

TDM is a systematic process or mathematical representation of the transportation system, with
data on population and economic activity and the principles of supply and demand, to estimate
travel behavior of people in the region.
They simulate the effect on traffic patterns (travel demand) of changes in the road
Estimate the amount of travel on the transportation system
Planning tool
Model users
o County
o Villages and towns
o Developers
o Consultants
o State
Travel Demand Modeling (TDM)
Analyzing general plans
Traffic impacts of development
Corridor studies
Evaluating traffic mitigation
Evaluating emission impacts for transportation conformity
Uses of the Model
Trip generation – How many trips occur in each zone?
Trip distribution – How many trips travel from one zone to any other zone?
Modal split – What travel modes do they use?
Traffic assignment – trips from one zone to another are assigned to travel routes
Four Step Modeling Process
Only as good as the inputs
Cannot predict changes in land use or attitudes
Average weekday model
Travel occurring only on the network – no off road traffic

Utilized NYSDOT Highway Design Manual Chapter 2
o Standards are Presented for Urban and Rural Arterials
o Within the Village boundaries of Canton and Potsdam, Route 11 is classified as an
Urban Principal Arterial
o Outside the Village boundaries of Canton and Potsdam, Route 11 is classified as a
Rural Arterial
o Existing Highway Section is described from 2 Miles west of Canton to 2 Miles east of
Potsdam
Design Standards
Derived From NYSDOT Region 7 Pavement Data Report (2013)
Project Limits Are Divided Into 15 Reporting Segments
Pavement Condition Varies From A Scale Of 6 To 10 Out Of 10.
o 9–10: Excellent, No significant surface distress
o 7-8: Good, Surface distress beginning to show
o 6: Fair, Surface distress is clearly visible
o 1-5: Poor, Distress is frequent and severe
o U: Under Construction, not rated due to ongoing work
