Transportation Management, Intelligent Transportation Systems, and Other Adaptations to Maturity in the Highway Sector

Transportation Management, Intelligent
Transportation Systems, and Other Adaptations to
Maturity in the Highway Sector

• David Levinson

2
Why Transportation Systems (Supply) Management

• We have largely built out existing transportation
  network (S-Curve).
• Highways are a mature system.
• More efficient (faster, safer, greater person
  flows (and vehicle flows)) use of existing
  transportation facilities without significant new
  construction.
• Complements TDM strategies - but not aimed at
  reducing demand.

3
Identify TSM Tools

• High Occupancy Vehicle Lanes (HOV Lanes)
• High Occupancy Toll Lanes (HOT Lanes)
• Bus Priority Lanes, Queue Jumpers, Signal
  Pre-emption
• Park and Ride Lots
• Ramp Meters
• Highway Helpers
• Variable Message Signs
• Electronic Toll Collection
• Highway Access Management
• Other Intelligent Transportation Systems
• Other

Background

• Ramp Metering in the Twin Cities
• 443 ramp meters in the metro area
• Zonal control
• Long delays at some ramps
• All meters were shut off for 8 weeks from Oct.
  to Dec., 2000.

7
Overview

• TDM
• What is it?
• Who are the players?
• Tools and techniques
• Effectiveness?
• Strategies for implementation

8
Understanding the jargon
TDM
TMA or TMO
TRO or TDM plan
9
TDM What is it?

• Demand driveneven demand oriented
• Attractive strategy (akin to least cost planning)
• reduces resource requirements (e.g., oil for
  fuel) on the input side of the balance sheet and
  the magnitude of waste material (e.g., air
  pollution) on the output side of the equation.
• Increase the efficiency of the transportation
  system at little cost

10
Different Types of TDM

• Alternative work schedules
• Staggered
• Flex time
• Four-day week
• Telecommuting
• Alternative modes
• Carpools
• Vanpools
• Subscription buses
• Parking management
• Preferential parking
• Parking pricing
• Parking ratios
• Park-n-rides

• Road Pricing
• Preferential HOV lanes
• Congestion pricing
• Transit
• Employer sponsored
• Employer subsidized
• Land use zoning
• Higher densities
• Mixed use development
• TOD

11
Issues/dimensions to understand

• Suitability of the metro area?
• Likely travel impacts
• For what type of travel (reductions in SOV use,
  trip generation, VMT or increases in transit
  use?)
• Costs
• For whom?
• Levels of acceptance
• Difficulty of implementation

12
Costs of Telecommunications?

• May induce travel
• May induce leapfrog development in the hinterland
• May encourage lone eagles
• Role of the Web?
• Long term effectiveness?

Implementation Transportation Management
Organizations and TROs
14
Products, Services, Facilitation from TMO

• Ridesharing information and assistance (e.g.,
  computerized carpool matchlists)
• Transit information and assistance (e.g., route
  maps and bus schedules)
• Convenience incentives (e.g., parking spaces)
• Financial incentives (e.g., transit pass
  subsidies)
• Program operations (e.g., vanpools)
• Alternative work schedules
• On-site amenities (e.g., child day care)
• Facilities improvements (e.g., bicycle lockers)

15
Case study Minneapolis

• Current situation
• 60,000 parking stalls (city owns two-thirds of
  them)
• 145,000 people work Downtown (roughly 2/3 use
  transportation alternatives)
• New Comprehensive Plan and Zoning Code codified
  specific TDM Plan requirements (99).
• New developments gt 100,000 sf produce a TDM Plan.
  Also, Public Works still exercises its blanket
  authority to require plans for smaller projects
  if warranted
• What is in the TDM plan?
