To address complex planning problems, Konheim & Ketcham assembles and analyzes data utilizing geographic information system (GIS) applications. Employing a wide variety of GIS, including MapInfo, ArcView, TransCAD, and Maptitude, K&K builds and maintains multi-level spatially-organized databases. By aggregating selected levels of data, we produce thematic maps that visually convey characteristics that are used to identify needs and formulate solutions.

K&K uses GIS in virtually all planning efforts. The characteristics of populations affected by any project are drawn from over 250 data fields from the U.S. Census. Land use features of the tri-state metropolitan area are being assembled into a cohesive picture of the region, with overlays of political jurisdictions and local places and districts. Roadways and transit lines are integrated into a regional network, with underlying information on physical and operating elements by link in each system. Public facilities, parks, cultural resources, zoning, truck routes and other defining features of New York City are contained in the database.

K&K uses GIS to develop origin and destination patterns by entering data on land uses and proposed developments that either generate or attract trips. Travel routes and times are calculated by using GIS to determine shortest distances along available roads and transit lines. These data are used interactively with transportation models imbedded in TransCAD or exported to other micro-simulation models, such as TRANPLAN. In other applications, the data are analyzed to determine existing levels of service or to simulate alternative future traffic conditions.

K&K has been a pioneer in presenting planned transportation projects, known as Transportation Improvement Programs (TIPs), in GIS formats so that government and community planners may evaluate them in relation to each other and to demographic and land use factors. These databases are retrievable by location, project type, sponsor, funding source, and year. K&K also uses GIS to identify optimum sites for facilities of all kinds that are compatible with other uses and with NYC's "Fair Share" goals.

K&K has developed other unique GIS applications, such as a highway noise model which extracts graphic and tabular information in the GIS database and then calculates noise levels, thus eliminating the tedious step of converting the database to a form compatible with stand-alone noise models.

In more straightforward uses of GIS, K&K arrays point data, such as flooding complaints or automotive accidents, to discern areas requiring priority attention.

The product of all these analyses are full color or black and white maps; the data may also be presented tabularly or in other graphic forms, such as bar graphs and pie charts. The result is that data are far more interesting and meaningful to a wide spectrum of people. K&K provides access to transportation planning information from its GIS archives and links to other related databases via the Internet on
