CTIS Background and Future
In December of 1998, a first step in the update of the California Transportation Plan, a team comprised of Department staff and regional agency partners identified the need to integrate existing long-range plans of both the State and regional transportation planning agencies by creating a map, using GIS software, of the current and resulting transportation system.
A Technical Advisory Committee (TAC) provided suggestions on tool design and data collection process. The TAC was comprised of Regional Transportation Planning Agency (RTPA) representatives and District staff, as well as representatives from Headquarters’ programs within the Department. A Policy Advisory Committee (PAC) provided overall project direction and scope, and included RTPA Executive Directors and Department management.
In January of 2001, the first version (v1.1) of the CTIS GIS Tool was released. The Tool was programmed using ESRI’s GIS ArcView 2.0 desktop application and Avenue programming language. The Tool used existing GIS base data, and customized tools and buttons to obtain information about the planned and programmed transportation projects. Version 2.0, still based on the ArcView 3x platform, was completed in November of 2006. The update included technical enhancements, a streamlined interface, and updated datasets. With the development of ArcGIS, the "Views" from ArcView were imported into individual ArcGIS MXD files for use in ArcGIS. Individual GIS shapefiles of the CTIS datasets and layer files, in addition to documentation, are available for download.
A web-based application with a central database is currently being developed. This application will greatly improve communication and facilitate the exchange of information within the Department, and with regional and local planning agencies. This application will also provide the ability to generate accurate information quickly in response to questions from the Business, Transportation and Housing Agency, the Governor, the Legislature, and the public.
The CTIS 3.0 application will be server-based and accessed through a web-browser. The end user will not require any additional software installed other than routine updates to browser software, and thus eliminating the need to purchase GIS software.
The web-based application will be directly linked to the Department’s California Transportation Improvement Program System for periodic downloads of programmed project data. This linkage will not only improve the timeliness of the CTIS project data but will also allow the Division of Programming to offer mapping of the programmed projects to all its users without needing to modify their application or to develop a separate web application.
