  1. Lec 7. Ch.3P3 Characteristics of urban travel Ch. 3 Part 3 (3.3): Topics • Trip types (purposes) • Three approaches for modeling trips • Travel behaviors of men and women • Trip purpose/temporal, spatial, and modal distribution of trips • Safety (covered in CE361) • Travel cost

  2. Typical trip types (used for demand forecasting) • Passenger trips are named by the trip purpose, classified by the trip origin: Work trips, Shopping trips, Social/recreation trips, Business trips, School trips – they are home-based or non-home based. Home-based trip HBO HBW Trips are defined as one-way movements. NHB Typical simple classes are: home-based work, home-based other, non-home-based • HBO is sometimes called HBNW (non work).

  3. Approaches for modeling trips Most popular modeling approach (UTMS) & we cover this one in this introductory TP planning course.

  4. Different travel behavior for men and women • Women’s (especially working women’s) trip making is more complex than men’s. • Women make more “chain trips” than men in general. • Trip chaining, or multipurpose trip making is difficult to model; there is so much uncertainty. UTMS does not include this type of trip making.

  5. Trip purpose/Temporal/spatial/modal distributions  Factors that need to be incorporated in demand forecasting For what purpose, at what time of the day, from where to where, by what mode is a trip made? And with whom, alone or with someone else?  This is an important question from a TP perspective. Peak Hr Volume? Which links are heavily used? Private auto, public transit, rail, walk, bike?  Modal demand levels

  6. Travel costs • Out-of-pocket costs to the user: costs associated with travel – fuel costs, parking fees, tolls, fares  This is what most of the drivers think of the cost for driving a car. • “Fixed costs” to the user: vehicle purchase, maintenance, and insurance costs  Many drivers do not consider these costs when they compare costs between driving a car and taking transit • “Social costs” to all: Include the cost of transportation services and goods that are not priced directly to the user but are incorporated into the price of the non-transportation good; public sector costs to build, maintain, and operate the transportation system; and the non-monetary costs to society of transportation-related impacts such as health effects of air and water pollution (externalities), pain and suffering from accidents, and travel time.

  7. Travel costs: Another way of looking at them - Direct and indirect costs • Direct costs: out-of-pocket costs, the cost of cars, insurance, building and maintaining roads, paying police officers, operating transit service, TP, etc. • Indirect costs: costs that occur as a result of transportation – congestion, accidents, air pollution, noise, solid-waste disposal, etc.
