1 Transportation System Issues and Challenges Traffic CongestionTraffic SafetyEquality of AccessEnvironmental Impacts
2 Traffic Congestion Demand & Supply; Trip Generation; Construct more capacity V.S. Transportation Management; (Funding Limitation.)ITSTraffic Control (e.g. Improved timing and coordination of urban arterial signal systems or freeway ramp meters.)
3 Traffic SafetyMotor vehicle fatality (most but decreasing because of improved highway design and maintenance, improved vehicle design, driver education and law enforcement activities.)SpeedingAdverse WeatherAviation fatality (very low compared to those for motor vehicles)Rail traffic (sporadic)
4 Equality of AccessThe poor, the elderly and the physically handicapped.Keep fares lowPublic transportation systems (includes airports, rail transit stations and intersections of streets with sidewalks) must be fully accessible to both wheelchair users and pedestrians.
5 Environmental Impacts Air quality (vehicle technology and vehicle maintenance -- emissions control devices and inspection programs)Energy consumption (improve vehicle technologies, new fuels)Land useSite-specific impactsdisplacement of residents and businesses due to construction of transportation facilitiesnoiseimpacts on wild-lifeimpacts on water qualityvisual impactstemporary impacts during construction (noise, dust, reduced water quality due to erosion of unprotected slopes, etc.)
