As SANDAG's 2021 Regional Plan unfolds, these are some important terms you need to know:
Regional Transportation Improvement Program (RTIP): A five-year listing of major highway, transit, and active transportation projects including project costs, funding sources, and development schedules. Compiled from priority lists submitted by local jurisdictions and transportation agencies.
Road Usage Charge (RUC): A road usage charge is a user fee system where all drivers pay to maintain the roads based on roadway utilization, rather than how much gas they purchase. Under a road usage charge, all drivers share roadway maintenance and repair costs based on what they actually use.
Shared Streets: Temporary roadway modifications that create safe and healthy spaces for people of all ages and abilities to bike or use other micromobility options (e.g., scooters, skateboards) while reducing vehicle miles traveled.
Series 14 Regional Growth: Population, housing unit, household, and job estimates for the future. The Series 14 Forecast projects several demographic and socioeconomic variables from the base year of 2016 to the horizon year of 2050 using data and assumptions about the region in the future.
Smart Growth: A compact, efficient, and environmentally-sensitive pattern of development that provides people with additional travel, housing, and employment choices by focusing future growth away from rural areas and closer to existing and planned job centers and public facilities, while preserving open space and natural resources.
Transit-oriented Development (TOD): Residential and employment growth that occurs near existing and planned public transit facilities
Transportation Demand Management (TDM): Policies and programs to reduce demand by automobiles on the transportation system, by promoting telecommuting, flex-time, bicycling, walking, transit use, staggered work hours, and ridesharing.
Value Pricing: A congestion management strategy that applies a surcharge to users of a transportation roadway or facility to reduce congestion during periods of peak demand. Value pricing is a way of harnessing the power of the market demand to maximize use of the available supply. Concepts include dynamic pricing, cordon pricing that charges are either dynamic or fixed within or into an area, and areawide pricing generally applied on a permile basis within an area.
Vehicle Miles Traveled (VMT): The total number of miles traveled on all roadways by all vehicles. Reducing vehicle miles traveled (VMT) can help ease traffic congestion and improve air quality
