Traffic Modeling

One tool that plays a part in the development of transportation plans is the traffic model. A traffic model uses information about traffic patterns (gathered through studies of actual traffic counts); anticipated location of future dwelling units, employers, and other attractors; size and capacity of roads, etc… and builds a model of what the future traffic conditions might be. Future road projects can be entered into the model and the effect of those projects can be analyzed. In this way, engineers and planners can make judgments about the relative benefits to the overall system of each road improvement or new road. The traffic models can also anticipate the number of trips that might be taken with alternative modes such as transit, pedestrian and bicycle by using person trips instead of only vehicle trips. As the LRTP was developed, traffic modeling was used to produce a list of future road improvements that give the greatest benefit for the dollars that are anticipated to be available. You can view a model run of the current traffic conditions with the existing road system below.
