Transportation Demand Analysis Lecture note Remember…
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
Home-based and Non home-based trips Trip purposes Remember… Peak hour Morning peak, noon peak, evening peak Home-based and Non home-based trips Trip purposes Work, education, shop, recreation, personal business, others Special studies: serving passenger, mode change Chaining behavior in large cities Transportation Demand Analysis
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) Transportation Demand Analysis
Transportation Demand Analysis Lecture note Geographical pattern
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
Time: Peak hour (daily) Purpose: work Involve in traffic congestion Radial trips Mainly: Time: Peak hour (daily) Purpose: work Involve in traffic congestion Move to other locations after city development Transportation Demand Analysis - Title
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) Transportation Demand Analysis - Title
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
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
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
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 Transportation Demand Analysis - Title
