Enhancing Road Traffic Safety in Inland Empire: A GIS Based Methodology to Identify Potential Areas of Improvement

It is well known that the major goal of transportation system is to enhance mobility and crashes are unwanted by-products which have to be minimized while achieving the primary goal. Although general people value travel time more than any other outcome of transportation system, traffic accidents impose huge economic burden on the society. A detail investigation of the State of California crash statistics showed over representation of fatal, injury, alcohol related crashes, road departure crashes, speeding related crashes in Inland Empire (http://www-nrd.nhtsa.dot.gov/departments/nrd-30/ncsa/STSI/6_CA/2005/6_CA_2005.htm) and identified as one of the major transportation issues affecting this region. This seed-grant proposal aims to investigate the reason behind the high crash statistics in Inland Empire and develop methodologies to identify potential areas of safety improvements using Geographic Information System (GIS). Researchers have shown that (Kim et al, 2006; Mitra et al, 2007) land use, economic activities, spatial traffic generators such as schools, universities, bars and pubs have strong influence in traffic crashes. Consequently identification of these spatial factors in relation to high crash location is important in enhancing traffic safety of a region as many aspects of roadway safety management may suffer from omitting spatial variables that have possible impact on road traffic crashes. To ensure a comprehensive safety analysis of Inland Empire, this researcher would like to form a partnership with experts in GIS and traffic safety from Cal State San Bernardino and Cal Poly Pomona to develop road-safety research program in new transportation center. This seed-grant also seeks to gather crash information, land use and socioeconomic data from local agencies and develop GIS databases for further and in depth analysis of traffic safety in Inland Empire.
