Study Notes
Transportation System Issues and Challenges
- Traffic congestion occurs when demand exceeds the capacity of the transportation system, characterized by slower speeds, longer trip times, and increased vehicular queuing.
Performance of the Transportation System
- Challenges include managing congestion, improving safety, providing equal access, and protecting the environment.
- Challenges also include incorporating new technology, securing financial resources, and developing adequate institutional arrangements.
Managing Congestion
- Traditional approach to congestion was to build more capacity, but this is often limited by funding and environmental concerns.
- Alternative solutions include sophisticated traffic control, urban land-use planning, and congestion pricing.
Traffic Safety
- Traffic accidents are a major concern, especially on highways and commercial air transport.
- Focus areas for improvement include vehicle safety, traffic safety research, and accident data collection.
Highway Traffic Safety
- The Vienna Convention on Road Signs and Signals (1968) standardized road signage globally.
- Types of signs include:
- Informative signs: provide information or instructions.
- Regulatory signs: instruct road users on what they must or should do.
- Warning signs: indicate hazards ahead.
Equality of Access
- Underserved groups include:
- Physically handicapped
- Elderly
- Poor
Environmental Protection
- Environmental impacts of transportation include:
- Air quality degradation
- Energy consumption
- Land use changes
- Site-specific impacts (e.g., noise, wildlife disruption, water quality degradation)
- Sensitive areas include:
- Habitats of threatened or endangered species
- Floodplains
- Wetlands
- Coastal zones
- Prime agricultural lands
- Historical or archaeological sites
- Wild or scenic rivers
New Technology
- Intelligent Transportation Systems (ITS) aim to:
- Improve safety
- Reduce congestion
- Increase mobility and accessibility
- Reduce environmental impact and increase energy efficiency
- Improve economic productivity
- Create a domestic ITS industry
- ITS technologies include:
- Improved traffic control systems
- Enhanced information provision
- Automation of administrative and regulatory functions
- Hazard warning systems
- New vehicle control systems
Funding
- Securing financial resources is a perennial challenge for public agencies and private firms.
- User charges include:
- Fuel taxes
- Direct fares or tolls
Institutional Arrangements
- Changes have occurred in response to perceived deficiencies in the existing system.
- Examples include adjustments to public-private sector relationships and attempts to overcome modal and jurisdictional fragmentation.
Transportation System Issues and Challenges
- Traffic congestion occurs when demand exceeds the capacity of the transportation system, characterized by slower speeds, longer trip times, and increased vehicular queuing.
- Challenges in the transportation system include:
- Managing congestion
- Improving safety
- Providing equal access
- Protecting the environment
Managing Congestion
- Traditional approach to congestion was to build more capacity, but this is limited by funding and environmental concerns.
- Alternative solutions include:
- Sophisticated traffic control systems
- Shifting from private automobiles to urban passenger transportation
- Better urban land-use planning
- Congestion pricing (surcharging users of public goods that are subject to congestion)
Traffic Safety
- Traffic accidents are a major concern for all modes of transportation, especially highways and commercial air.
- Focus areas for improving traffic safety include:
- Improving safety of vehicles
- Traffic safety research and development
- Collecting accident data
- The Vienna Convention on Road Signs and Signals was created in 1968 to standardize road signs and signals.
Highway Traffic Safety
- Types of highway traffic signs:
- Informative signs (provide information about an object or give instructions)
- Regulatory signs (instruct road users on what they must or should do)
- Warning signs (indicate hazards ahead on the road)
- Examples of each type of sign are given.
Equality of Access
- Providing equal access to the transportation system for all people is an ongoing challenge.
New Technology
- The Intelligent Transportation Systems (ITS) program aims to:
- Improve safety
- Reduce congestion
- Improve mobility and accessibility
- Reduce environmental impact and increase energy efficiency
- Improve economic productivity
- Create a domestic ITS industry
- ITS goals will be achieved through:
- Improved traffic control systems
- Better provision of information about the transportation system
- Automation of administrative and regulatory functions
- New systems for warning users of hazards
- New vehicle control systems
- Other applications of electronic technology
Funding
- Securing adequate financial resources is a challenge for both public agencies and private-sector firms.
- Common forms of user charges:
- Fuel taxes
- Direct fares or tolls
Institutional Arrangements
- New institutional arrangements have emerged in response to perceived deficiencies in the existing system.
- Changes have been made to the relationship between the public and private sectors and attempts to overcome modal and jurisdictional fragmentation.
