DESIGN DEVELOPMENT PROCESS After all data has been gathered, our team will prepare the design documents necessary for this project. In the design process, we will assess each intersection individually using as -built drawings (where available), the GIS signal inventory, and the field review data to determine exactly what in -cabinet equipment and precise quantities of each will be required for each intersection depending on the CMS system hardware and software chosen by the key stakeholders. Our team will work closely to confirm that the utility coordination information is incorporated into the design process and limit re -work or other issues due to unseen conflicts. The complexity level of this project lends itself to a simplified review process in which preliminary (60%) and final (100%) plans should be submitted for review. These reviews will need to be conducted by the Key Stakeholders and INDOT, where applicable. Included in these reviews will be a review of the environmental document that will accompany the construction documents. Our team will develop and work with INDOT on approval of any proprietary materials requests, as we know that selecting hardware and software that is compatible with the city's existing infrastructure is key to a successful deployment. Additionally, our team will work with the city and INDOT to develop or update the Methodology of Understanding (MOU) for any INDOT owned signals that will require local equipment in the cabinets. We will also verify the construction documents reflect the overall construction schedule such that contractors are required to complete the work on the agency's schedule in lieu of the contractor's preferred schedule. With the anticipated need to update existing signals due to restrictions limiting the deployment of the CMS equipment, our team is fully equipped to handle any issues that may arise. Our environmental staff has navigated the LPA process for every size project and will coordinate with the necessary agencies to verify the required permits are received from application to acceptance. Based upon the findings of the Signal Upgrade Prioritization Model, and in conjunction with the city, intersection where upgrades will be provided will be identified for design. The same experienced engineering staff who will be providing the CMS design and who previously worked within the tight confines of downtown South Bend on the SmartStreets project will be performing the signal modification designs. The traffic engineering staff will review the in -field data and survey data collected, if needed, and maximize the cost and time savings for the City of South Bend. Our team will include our experienced roadway team should any drainage, sidewalk, curb or ramp locations need to be modified. All the available information will be reviewed and discussed with the city to confirm their needs are met prior to design. Any existing local traffic standards/preferences and appropriate INDOT standards will be utilized in these designs. RECOMMENDATIONS A technical memorandum will serve to document the results of the detailed field inventory, the design determinations and final design decisions. The report also will document any concerns or recommendations that our team has about the existing signal equipment, intersection geometry or pedestrian operations. These issues would be considered non -critical but may enhance the operations or safety of the traveling public. All aspects of the signal system will be reviewed throughout the project on an ongoing basis, and these recommendations will be compiled in the final report, noted in a meeting or summarized in a memorandum during the project depending on their urgency or significance. If these issues are operational in nature, analysis may be provided to show the benefits of the recommendations. Throughout the project, any safety issue that is deemed a threat to the traveling public or pedestrians will be brought to the immediate attention of the local agencies.
