San Bernardino County Comprehensive Transportation Plan
San Bernardino County's transportation needs are influenced by many factors.
Some are obvious, such as a growing population and changes in the locations
of jobs, services, shopping, and recreation opportunities. Social and
economic changes are less obvious but have a surprisingly strong effect
on transportation choices.
Improving the county's transportation system to address these changes can be very costly, and progress often seems painfully slow. Most major transportation projects take years to complete and must be planned before construction begins. Because of this, both the state and federal governments require plans to identify a 20-year transportation program and how to pay for it.
Analyses show that the transportation needs of San Bernardino County and the southern California region far outweigh financial resources. Solving this problem will require some difficult policy choices.
An effort is underway to update the county's Comprehensive Transportation Plan (CTP) to the year 2030. Goals and objectives, performance indicators and alternative transportation scenarios are being defined and analyzed to create a preferred plan alternative. In cooperation with local agencies, this work has involved updating the socioeconomic forecasts to the year 2030 and the base year streets and highway network for the CTP traffic model.
The updated CTP will:
- Identify transportation improvements and strategies to enhance system performance and achieve emission reductions to meet air quality requirements; and
- Integrate goods movement strategies currently under development and serve as a basis for action programs to be implemented through the Congestion Management Program.
Because this plan addresses controversial issues, broad participation is essential if there is to be support for the plan and its policies. The planning process relies on input from city and county governments, concerned citizens, businesses, air quality agencies, and transportation specialists. SANBAG encourages participation in choosing and supporting the best course of action.
