TRAFFIC SIGNAL FIRMWARE CONVERSION AND SOFTWARE INTEGRATION FOR AN EXISTING SIGNAL NETWORK IN PASADENA, CA

摘要

The City of Pasadena’s traffic management center currently monitors and operates over twohundred and fifty signals throughout the City. The operation and maintenance of existingtraffic signals and traffic communication network is facilitated from the Traffic ManagementCenter (TMC) through use of three different traffic management systems: Series2000,QuickNet Pro, and Siemens i2. The City is transitioning to newer traffic signal controllers,standard traffic signal firmware, and a more centralized advanced traffic management system(ATMS). The purpose of the conversion is to provide a more technologically advanced andspecialized traffic signal control means to address the most challenging traffic conditions.This paper will describe the thorough process of converting the base timing parameters forover one hundred and twenty signals to a new firmware, inputting and uploading theconverted firmware into the existing central system software (i2), preparing intersectiongraphics, and re-allocating data channels of the existing links to accommodate the maximumnumber of controllers per channel. The paper will also describe the limitations brought on bythis transition, and the difficulty of deploying and implementing new firmware and softwareusing older communication infrastructure.
