GIS-ALAS Advisory Committee Meeting

August 28, 1997


Present: Scott Burklund, Reg Souleyrette, Tim Strauss, Jack Latterell, Joyce Emery, Alicia Caton, Michael Pawlovich, Jaime Reyes, John Nervig, George Oster, Stephen McGregor, Mark Alexander, Jim Dickerson

Status Report

GIS-ALAS is currently being developed using ESRI products. Distribution will occur by CD (using ArcView) and the Web (using MapObjects). Both distribution options will be free to users. ESRI may have a new product coming out this fall that would enable us to use our CD product more directly on the Web. Alabama's system also has a Web component.

Concerns were expressed about confidentiality and other issues related to public access to accident data via the Web, especially for data on a single accident or a specific node number. We would need to password protect the Web application or some of its components. We could also strip off the last 4 digits of the node number or create thematic maps (e.g., to show the number of accidents at particular location). An assessment needs to be done of potential uses and users of the product to determine specific functionality implementation requirements.

The file conversion is basically completed. The CD product should be ready for testing by the middle of the September. An initial version of GIS-ALAS, with data for the Central Iowa transportation center, will be available for testing. The following were identified as candidates for the initial testing process:

Harold Jensen, Jaime Reyes/John Nervig, Stephen McGregor, an enforcement agency to be chosen in consultation with Terry Dillenger, a representative of FHWA, and Alicia Caton.

Tim Strauss will look at statistical analysis packages that potentially could be used to analyze accident pattern and causation (e.g., Xgobi, pointstat, etc.). A professor at ISU has a database of weather conditions and wants to match it with accidents. We also plan to connect our work of this nature to what Michael Zhang is doing.

John Nervig will get copies of sample screens of Access-ALAS to Michael. We plan to have good coordination between the GIS-ALAS and Access-ALAS efforts.

Avenue of the Saints Project

George Oster talked about the Avenue of the Saints and his concern about how smaller communities will handle necessary fire and emergency services, as well as how response patterns will be affected. There are 871 independent fire departments in the state. Most small and undermanned, and underfunded, and we need to determine the effect of the Avenue of the Saints on these departments. (A possible positive impact is quicker ambulance service to Iowa City) We can use ALAS to get a description of current response patterns for the four affected counties. They have a researcher at the University of Iowa.

UNI Update

A pilot GIS-T database is being developed in ArcView. Elements include USGS data, elevation, and ambulance service locations. In Phase 2, demography and a whole list of other data will be added. Three geography graduate students are doing GIS-T in the department. There is a new GIS research lab at UNI. The Blackhawk County Department of Justice has a grant for their E911 upgrade, which will include AVL, routing, and dispatch.

GIS/Crash data conference and other matters

The GIS/Crash data conference will be held November 6. It will include a presentation of DOT/CTRE activities (PC-ALAS, Access-ALAS, GIS-ALAS), presentations from other states, a presentation from UNI, and a discussion of AVL/dispatch/emergency medical response applications. We would also like to get law enforcement from Dubuque, Des Moines, and West Des Moines involved.

CTRE will prepare a one-pager for the national model exhibit in Scottsdale that Jack Latterell is attending. In addition, Tom Welch needs one or two overheads on GIS-ALAS.

Visit to Driver Services

Joyce Emery and the CTRE project team visited Driver Services in Des Moines to discussed possible ways to improve the coding of accident locations. CTRE and the DOT/Transportation Data will follow up on this issue.

 

CTRE is an Iowa State University center.
