3. Remember… Trip Travel Journey Tour Round trip Chain
a movement from an origin, O, to a destination, D, for a purpose, P.
Travel
mainly used for behavior of trip making
Journey
mainly used for a set of trips
Tour
includes, at least, 2 trips (go and return)
Round trip
travel in form of a tour
Chain
a sequence of trips
Transportation Demand Analysis

4. Home-based and Non home-based trips
Remember…
Peak hour
Morning peak, noon peak, evening peak
Home-based and Non home-based trips
Chaining behavior in large cities
Transportation Demand Analysis

5. Remember… Trip purposes
Work, education, shop, recreation, personal business, others
Special studies: serving passenger, mode change
Aggregation due to sparse data
(e.g., discretionary vs. non discretionary trips)

Geographical pattern

7. Geographical patterns of urban trips
1- Radial trips
2- Ring trips
3- Local trips
4- Central business district (CBD) trips
5- Trips to special land uses
Transportation Demand Analysis - Title

8. Time: Peak hour (daily) Purpose: work Involved in traffic congestion
Radial trips
Mainly:
Time: Peak hour (daily)
Purpose: work
Involved in traffic congestion
Move to other locations after city development
Transportation Demand Analysis - Title

9. Between radial corridors
Ring trips
Mainly:
Converted from radial trips to peripheral destinations (Peripheral markets)
Between radial corridors
No Joint routes due to the lower demand  No public transit route
More than one ring may formed (e.g., London, Moscow, Medina)

10. Local trips (in residential zones)
Also named as “to/from” trips
From houses to transportation systems
From transportation systems to houses
Walk trips to adjacent land uses
Transportation Demand Analysis - Title

11. Often, by Walk, Bicycle, Motorcycles
CBD trips
Often, by Walk, Bicycle, Motorcycles
Due to city size, by: Taxi, Bus, BRT, Metro
Transportation Demand Analysis - Title

12. Trips to special land uses
Special land uses: Stadiums, Airports, Parks,…
Different patterns of time and travel
Airport: passengers, crew and accompanies
Stadium: day, time and flow …
Transportation Demand Analysis - Title

13. Transportation master plans
Mainly focus on peak hour:
Accounting type 1 and 2 (i.e., radial and ring trips)
Ignoring type 3, 4 and 5
