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

Freight Activity

2,922 surveys completed

o Canton (Westbound) - 1,484 (36% capture rate)

o Potsdam (Eastbound) - 1,438 (50% capture rate)

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
