Long Range Plan
In an attempt to meet the community’s transportation needs, the LACRPC has developed and continues to update the 2045 Long Range Transportation Plan. The 2045 Long Range Transportation Plan is a strategy of capital improvement programming developed to guide the effective investment of public funds in transportation facilities. The Plan provides the framework from which the area’s short-range Transportation Improvement Program (TIP) is developed.
Transportation Improvement Program
The Long Range Transportation Plan is monitored and implemented through the Transportation Improvement Program (TIP) process. Coordinating the short-range TIP for the Lima Urbanized Area represents one of the LACRPC’s major responsibilities as the Metropolitan Planning Organization (MPO). The TIP provides a four-year prioritized listing of a bikeway/pedestrian walkway, bridge, highway, transit, and paratransit projects, utilizing federal funding.

Travel Demand Model
A Travel Demand Model (TDM) is a computerized simulation model that allows transportation planners to develop future traffic conditions and identify alternatives to address future congestion in current planning activities. Planning Commission staff works with ODOT personnel to maintain a traditional 4-step gravity model that reflects trip generation, trip distribution, mode choice, and traffic assignment. The model is comprised of 366 travel analysis zones (TAZ) which reflect zonal transportation network characteristics such as roadway speeds, lanes, and widths, as well as 17 socio-economic data items reflective of the TAZ’s unique population, employment, households, and dwelling units. The model is sensitive to truck flow and transit usage as well as time-of-day that includes information across four periods: AM peak, midday, PM peak, and overnight.
