The Traffic Congestion Toolbox


Methods to reduce traffic congestion fall in two categories:

  • increase capacity and
  • reduce loading.

Increase capacity

  • Increase capacity on existing roads
  • Identify and develop arterials Reduce bottle necks on existing routes
  • Additional freeways
  • Hi tech traffic control devices
  • Update definition and control use of road reserves
  • Have a dynamic long term plan

Reduce loading

  • Toll roads
  • Streamline any and all passenger and freight carrier services
  • Develop high occupancy vehicle concept (HOV lanes)
  • Dedicated bus routes
  • Park and Ride facilities coupled with bus routes
  • Lift clubs (car pooling), with Park and Ride and address insurance obstacles
  • Penalise single occupant vehicles
  • Ramp metering on freeways (to regulate peak flows)
  • Upgrade rail facilities to carry more freight, to compete with trucks
  • Upgrade old passenger rail facilities
  • New rail links (eg Gautrain / Soweto monorail)
  • Non Motorised, Intermediate Motorised Transport (NMT) and (IMT) - bicycles etc
  • Motor cycles (commuter type) (address safety obstacles)
  • Commuter vehicles ("bubble cars" use less road space)
  • Work from home
  • Stagger work hours (flexi-time)
  • Stagger business hours
  • Start next industrial hub west of city to reduce travel distances for some
  • Inner city private vehicle tax (example London) (just to keep in mind)
  • Electric city vehicles (plug in and charge batteries saves on tank fuels)
  • Alternative fuels, fuel cells, hybrid vehicles, to be on this agenda towards minimising fossil dependance

    Application of alternatives

    Not all of these are necessarily applicable or easily implemented and some are already receiving attention. This presentation attempts to

    • To address those alternatives that are realistically achievable in the short and intermediate term
    • That are likely to provide the best return at the lowest cost, but mainly to
    • Establish a policy towards the here-in stated "Seven Principles for Planning Efficient Roads", and to
    • Identify these alternatives within a charter of objectives and a dynamic visible forward looking plan

    intermediate means of transport (IMT) and to discuss the issues of reform
    investment and public participation that are to firmly entrench NMT as
    a recognised and fully supported form of transport in South Africa

    • Adding More Capacity
    • Increasing the Number and Size of Highways
    • Providing More Transit and Freight Rail Service
    • Operating Existing Capacity More Efficiently Getting More Out of What We Have
    • application of advanced technologies,
    • other strategies that do not rely on advanced technologies,
    • Modify Travel and Land Use Patterns to Spread the Load Travel Demand Management (TDM),
    • Non-Automotive Travel Modes,
    • Land Use Management,
    • Put more people into fewer vehicles,
    • Designers must think "outside the box" find creative ways to incorporate new designs
