Component

The City of Ames in Iowa is a medium-sized community, which has an estimated population of 56,510 (2008). The Ames Area Metropolitan Planning Organization (AAMPO) was designated in 2003. In addition, the City of Ames is home to Iowa State University with an enrollment of 27,945 as of Fall 2009. During the period 2002-2008, on average 1,000 traffic crashes (of property damage over $1,000) occurred per year. This trend will continue in the future and may increase in view of changes in demographics and land use. However, to date, safety is not explicitly considered in the city’s transportation planning process. Historically, the approach to safety problem identification and mitigation has been “reactive”, black spots or hot spots have been identified by ranking locations based on the crash frequency and severity, mainly at the corridor-level and without considering the exposure rate (vehicle miles traveled) and socio-demographics characteristics of the study area. Therefore, a larger study analysis area at the Transportation Analysis Zone (TAZ) level or the network planning-level should be used to address the needs of development of the community in the future and incorporate safety into long-range transportation planning process. This paper examines how existing planning models (for example, the PLANSAFE models presented in NCHRP Report 546) can be used for forecasting safety in the future in a medium-size community, due to changes in socio-demographics, traffic demand, road network and countermeasures. In addition, United States Road Assessment Program (usRAP) Risk Mapping is investigated for application in the city. Incorporating safety into long-range transportation planning can assist planners and decision-makers in predicting how changes in demographics, land use, and roadway infrastructure investments can impact traffic safety, and help set safety performance targets for the city.
