摘要: |
The Interactive Graphics Intersection Design System (IGIDS) is a computer software program developed for TxDOT that assists engineers in the analysis and design of individual, at-grade intersections. IGIDS is a MicroStation application which (1) contains geometric and traffic data, as well as signalization definition tools and pavement striping definition and tabulation tools; (2) contains built-in analysis tools for vehicle turning templates; horizontal sight distance checking for stop sign, yield sign, and no control; vertical sight distance checking within the horizontal sight triangle; and Highway Capacity Manual (HCM) Chapter 9 procedures; and (3) contains interfaces to external analysis programs for the TEXAS Model for Intersection Traffic (TEXAS), the TxDOT Automated Plan Preparation System (APP), and the Signal Operations and Analysis Package (SOAP). IGIDS can operate in English or metric units. IGIDS also has an extensive set of training materials. Data for both the built-in and external analysis tools are drawn from a common database that is maintained by IGIDS. Much of this data is extracted from the graphical intersection geometry definition that is constructed by the user. Some non-graphical data, such as volumes, must be entered through the keyboard. |
