Over 61 percent of this growth, 2.479 million people, will be the result of net migration into the state" - http://demog.state.nc.us/

General Travel Demand Information
- Please identify those DOT divisions / groups that collect, forecast, analyze, or make other uses of highway travel demand measures (including VMT, AADT, ton-miles, or other measures). Not all rows need be completed if there are no relevant contacts.
- Travel Demand Measurement: Please identify the primary measures of travel demand (either current or projected) currently gathered by your agency.
Measures of Current Travel Demand
| Measure | Yes | No | Comments |
|---|
| VMT | X | | Reported annually after HPMS data provided to FHWA. Note: Statewide reporting procedure needs to be updated. GIS unit maintains and reports this information per county and for entire state. |
| AADT | X | | Primary system is collected every year unless entire county falls under an urban area. Urban area counts split b/w odd and even years. Interstates counted every year. Secondary roads are every 2 years. |
| Ton-miles | | X | NCDOT does not collect. Referenced info found at BTS and FAF websites supported by FHWA |
| Vehicle ownership | X | | DMV maintains vehicle registration records - currently over 7 million registered vehicles in the state |
| Other | | | |
| Other | | | |
| Other | | | |
Measures of Future Projected Travel Demand
| Measure | Yes | No | Comments |
|---|
| VMT | X | | Projections to years 2010, 2020, 2030 have been made by GIS unit for each county. Based solely on historical trend. |
| AADT | X | | Traffic forecasts are developed for projects throughout the state to help determine project scope, design/traffic operation decisions, and environmental/social impacts |
| Ton-miles | X | | Currently developing a statewide truck travel demand model to ascertain impacts of truck movement on congestion, level of service. Model output will be input for another study on truck profiles, vehicle class and impacts of overweight trucks to pavement/bridges. Ton-miles, tonnage, commodity by value data expected from FHWA late July/early August |
| Vehicle ownership | | X | No reported predictions are made on vehicle registration |
| Other | | | |
| Other | | | |
| Other | | | |
- Travel Demand Measure Usage: Please identify specific ways in which travel demand measures (either current or projected) are currently used in your asset management program or for other purposes such as planning, programming, or maintenance activities.
Measures of Current Travel Demand
| Measure | Comments |
|---|
| VMT | Mostly used in charts/graphs to show increasing level of demand on system vs. slower growth of revenue. Disparity b/w VMT and revenue has lead to policy discussions with Board of Transportation and outreach to public to seek new ways to fund transportation (October 2005) |
| AADT | Future projected more important for planning/programming |
| Ton-miles | Not used in planning |
| Vehicle ownership | Role in trip generation in travel demand models - trip generating capacity tied to income for housing and commercial vehicle info collected for employment |
| Other | |
| Other | |
| Other | |
Measures of Future Projected Travel Demand
| Measure | Comments |
|---|
| VMT | Same issue as current but further disparity in the future between VMT and revenue |
| AADT | Traffic forecasts are developed for projects throughout the state to help determine project scope, design/traffic operation decisions, and environmental/social impacts |
| Ton-miles | If initiatives mentioned under "comments" section of Q 14 are used and emphasized, ton mile measurement could have impact on improved strategy to address infrastructure maintenance and enforcement of overweight trucks |
| Vehicle ownership | |
| Other | |
| Other | |
| Other | |
Self-assessment
- My state DOT:
| | Agree | Neutral/ Don't Know | Disagree | Comments |
|---|
| Performs a statewide travel demand forecast or survey at regular intervals (e.g., annual VMT estimates) | X - not a forecast but an annual VMT calculation based on ADT and historical information. | | | |
| Performs a statewide long-range transportation infrastructure plan | X - current Plan was adopted in 2004, Board of Transportation recommends Plan be updated every 2 years | | | |
| Performs statewide long-range transportation financial planning | X - DOT performs cash forecasting via Financial Management Division. Forecasts are:- 1 year
- 36 month
- 8 year forecasts
| | | |
| Includes long-range infrastructure planning as part of the asset management process | Statewide Plan outlines investment goals under three areas of system improvement - Maintenance/Pres., Modernization, Expansion. Transportation Plans for local areas generally focus on capacity, operational and safety improvements not maintenance | | | |
| Includes long-range financial planning as part of the asset management process | Recent example of Moving Ahead program allowed use of cash balances in trust funds to be applied towards maintenance/traffic operational improvement projects | | | |
| Includes operations and maintenance as part of the asset management process | X - just starting new Highway Performance Based Management overseen by Operations | | | |
| Includes travel demand forecasting as part of the asset management process | X - will have some role in LOS standards instituted under Highway Performance Based Management | | | |
