3 Developing p g a Vision Where does your community see itself when it is fully developed? Land use versus transportation What comes first, the chicken or the egg? 3

4 Developing a Vision Community plans often includemultiple goals that compete with each other Charming, historic, pedestrian friendly downtown Homes near natural amenities Economic development (jobs & retail) along major highway Can your land use vision accomplish your goals? 4

5 Planning & Forecasting Basic components of transportation forecasts Land Use Households Population Employment (retail & non retail) Transportation Regional i l& local lsystem (public roads, transit routes) Route characteristics (functional class, speed, capacity) Origin destination ii d i i information, i trip rates Travel Behavior Inventory 5

6 Planning & Forecasting Types of Tools & When to Use Them Large Scale Region/State APO/MPO County/Local Transportation Plans Corridor Analysis Travel Demand Forecasting Small Scale Development Building Traffic Impact Studies Intersection Analysis ITE Trip Generation Macroscopic Highway Capacity Manual Analysis Microscopic Simulation Mesoscopic Traffic Operations 6

Form: Income, Vehicle Ownership, Mode Choice, Origin Destination Data; LEHD: Employment Origin Destination Data Travel Behavior

7 Planning & Forecasting Travel Demand Forecasting Travel Demand Models The use of tools that integrate land use, socioeconomic characteristics & travel patterns to provide traffic forecasts Basic inputs Census Bureau Short Form: Households, Population; Long Form: Income, Vehicle Ownership, Mode Choice, Origin Destination Data; LEHD: Employment Origin Destination Data Travel Behavior Inventory, Mode Choice, Trip Length, Number of Trips, Vhil Vehicle Ownership Roadway Characteristics Lanes, Functional Classification, Speed, Capacity 7

Traffic forecasts based on preferred routes Areas of Congestion 8

9 Planning & Forecasting ITE Trip Generation Determination of trips to & from a site based on development characteristics Basic inputs Development type & size (units, square feet, students, etc.) Methodology Trip rates based on historical data What are the findings/info it provides? Enter/exit trips based on the appropriate trip rates Trips applied to transportation network 9

10 Planning & Forecasting Traffic Operations Highway Capacity Manual lanalysis (macrosimulation) Peak hour assessment of the capacity of a transportation system Microsimulation Assessment of a transportation system through the replication of each traffic element. Basic inputs Traffic volumes, vehicle composition, driver behavior, lanes, speed limits, signal timings, traffic control What are the findings/info it provides? Operational analysis of existing system The effects of changes in traffic elements or the transportation system 10

11 Planning & Forecasting Which forecasting tool do I use? Depends on Size of proposed development Regional significance Number of impacted intersections Insert hammer, screwdriver, wrench 11

13 Pulling it all Together Developing plans Think holistically don t complete one element at a time Don t let one element get too far ahead of the others Technical analysis findings need to be fed back into the planning process Identify who should pay for improvements? Update capital improvements plan (CIP) Growth pays py for itself 13
