Transportation System Issues and Challenges Traffic Congestion Traffic Safety Equality of Access Environmental Impacts
Traffic Congestion Demand & Supply; Trip Generation; Construct more capacity V.S. Transportation Management; (Funding Limitation.) ITS Traffic Control (e.g. Improved timing and coordination of urban arterial signal systems or freeway ramp meters.)
Traffic Safety Motor vehicle fatality (most but decreasing because of improved highway design and maintenance, improved vehicle design, driver education and law enforcement activities.) Speeding Adverse Weather Aviation fatality (very low compared to those for motor vehicles) Rail traffic (sporadic)
Equality of Access The poor, the elderly and the physically handicapped. Keep fares low Public transportation systems (includes airports, rail transit stations and intersections of streets with sidewalks) must be fully accessible to both wheelchair users and pedestrians.
Environmental Impacts Air quality (vehicle technology and vehicle maintenance -- emissions control devices and inspection programs) Energy consumption (improve vehicle technologies, new fuels) Land use Site-specific impacts displacement of residents and businesses due to construction of transportation facilities noise impacts on wild-life impacts on water quality visual impacts temporary impacts during construction (noise, dust, reduced water quality due to erosion of unprotected slopes, etc.)
