SBIR-STTR Award

Advance Technologies is proposing a formal software development effort to translate the State Transition Logic algorthims developed under NCHRP Project 3-66. We are proposing the use of free software such as GNAT, Linux and Umbrello to assist us in the software development. Advanced Technologies has been developing real time, safety critical, Ada83/Ada95 software for twenty years. We plan to use UML during the requirements and design phases of development. Both Ada95 and C software packages/modules will be generated from UML object models. The software will be compiled using GNAT and gcc. Unit testing, integration testing, and formal qualifications testing will be performed.

Phase II Project Scope: ATI has developed an open source Signal Control Programming Environment (SCOPE) that ? Implements Actuated Control with Min Recall Mode, Max Recall Mode, Gap Out Mode, Max Out Mode, Presence Mode, Lane-by-Lane Control. ? Contains a Pretimed Mode allowing control of 3-leg, 4-leg, and Texas Diamond Intersections ? Can be easily ported to any operating system. ? Can handle 64 sensor inputs and 8 Pedestrian calls (and can simulate both) ? Runs on ? Linux based PC (used for concept and unit testing). ? A PowerPC prototype board ? An Advanced Traffic Controller ? Has selectable NEMA-TS2 or ITS output formats. ? Is dual redundant, containing two different implementations of the same logic. ? Contains unique interfaces • An Advanced Traffic Controller interface. • A Java internet interface • A wireless Android Tablet interface ? Has the ability to simulate 64 actuated inputs (new call, has call, had call). This SCOPE Phase II effort will create a stand alone separate and reusable (by other programs) NTCIP interface. This interface will permit SCOPE to communicate with Central Management Systems used in mid to large municipalities.
