Title: Planning for Urban Freight Movement


1
Planning for Urban Freight Movement
  • By
  • Arun Chatterjee
  • The University of Tennessee, Knoxville

2
Scope of My Presentation
  • Traditional planning engineering oriented
  • Vehicle-based analysis
  • Internal through movements of trucks
  • Tools for planning and forecasting
  • Examples of common issues and opportunities
  • Practical difficulties

3
Internal Movement- Modes Vehicles
  • Nearly 100 trucks
  • Majority SU and trucks and vans of different
    types
  • Some large combination trucks

4
Services of Different Hierarchy
  • PUD between major centers, e.g., an airport and a
    hub center of UPS/FedEx large combination
    trucks
  • PUD of containers from one rail terminal to
    another, e.g., in Chicago large trucks
  • PUD between warehouses and offices/stores medium
    size trucks and vans
  • PUD between a break-bulk terminal and
    offices/homes small trucks and vans

5
Service Vehicles
  • Service vehicles of plumbers, electricians, etc.
    (Should these be treated as freight vehicles?)

6
Types of Commodities
  • Construction materials
  • Food products
  • Consumer goods TV, furniture, etc.
  • Petroleum
  • Small packages
  • Mail, etc.

7
Long-Range Planning Process of MPOs
  • 20-year planning horizon
  • Relies on forecasting models
  • Two major components
  • Land use forecasting
  • Travel forecasting
  • How is freight transportation treated?

8
Land Use Planning and Forecasting
  • Does it address truck terminals and their
    locations- now and in the future?
  • Does it address warehousing and their locations -
    now and in the future?
  • How are the other freight generators such as
    seaports, airports, and rail-truck intermodal
    yards treated? (Expansion relocation needs)
  • Is access to freight facilities examined?

9
Travel Forecasting Models
  • Travel forecasting models constitute a major
    component of the planning process
  • Four-step modeling procedures primary focus has
    been on passenger trips by automobile transit
  • Research on travel surveys and mathematical
    models commonly focus on person/passenger trip
    making and mode choice

10
Truck Travel Forecasting Models
  • Only a few MPOs are developing these models
  • Lack of good data on truck travel
  • Need for truck trip surveys and truck counts
    (by types)

11
Truck Trip Modeling Questions to Be Addressed
  • How to classify truck trips-- size, type of
    service?
  • Trip generation models for productions and
    attractions variables to use employment, or
    commodity oriented?
  • Trip distribution- trip based or tour based
    models? (Pick-up delivery trucks use trip
    chaining/tours.)

12
Truck Trip Modeling- Questions(Cont.)
  • Traffic assignment - need a separate network for
    large trucks?
  • If auto trips and truck trips are assigned
    separately, how to account for their combined
    impact on capacity and speed?
  • Should have the ability to identify truck trips
    even after combining with auto trips for
    assignment for truck route planning.

13
Special Techniques for Developing a Truck Trip
O-D Matrix
  • An O-D survey for truck travel is expensive and
    complex
  • Mathematical techniques for creating truck trip
    matrix that can replicate truck counts
  • Need truck counts at strategically selected
    locations
  • Need information on truck trip generators and
    truck prohibitions
  • Baltimore area MPO recently utilized this
    approach

14
Problems Opportunities
  • Long-range short-range
  • How to identify these?
  • Role of freight advisory committees for
    identifying current problems and opportunities

15
Opportunities Deserving Immediate Attention
  • Planning oriented
  • Traffic engineering oriented

16
Planning Oriented Opportunities
  • Providing off-street loading docks/space for
    buildings zoning ordinance should specify
    requirements

17
Planning Opportunities (Contd.)
  • Developing freight terminal complexes
    transportation parks (or freight villages) land
    use plans should provide for these.

18
Traffic Engineering Oriented Opportunities
  • Curbside loading zones
  • Improvements along routes commonly used by large
    trucks
  • Intersection improvements at locations with heavy
    truck use

19
Cut-Outs for Loading Zones
  • Cut-outs/turn-outs of wide sidewalks for loading
    zones

20
Curbside Loading Zones
  • Location
  • Length and marking
  • Hours of operation
  • Time limit for turnover
  • Different zones for different types of vehicles
  • Enforcement

21
Curb Space Management
  • Competing users of curbside
  • Buses
  • Taxi cabs
  • Service vehicles
  • Trucks of different types
  • Who gets priority?

22
Through Movement Common Problems
  • High volume of heavy trucks on arterial highways
    noise, traffic congestion, safety concern, etc.
  • Lane use restrictions for trucks
  • Rail-highway grade crossings safety

23
Difficulties to Overcome
  • General public has a negative attitude toward
    freight service providers
  • Elected officials may not give high priority to
    freight vehicles (freight does not vote) and
    freight planning
  • Need cooperation of private freight companies,
    but they want fast action and are skeptical about
    public agencies

24
Concluding Remarks
  • Use a practical approach
  • Address major concerns and issues of both public
    and private sectors
  • Need to implement a few strategies quickly to
    gain confidence of private sector
  • Need to publicize the case/need for freight
    transportation using news media, chamber of
    commerce, trade associations, etc.
