Frederick County, Virginia is seeking professional traffic engineering services on an as needed basis for traffic studies, modeling, analysis, design and review of traffic signals and intersections, signs, roadway extensions, new road alignments, pavement markers / markings, guardrail, lighting, roadway safety improvements and for other traffic engineering related projects. Traffic Data Collection, Analysis and Simulation This work shall include the utilization of professional traffic engineering expertise to analyze traffic flow in congested or crash prone areas, and to make recommendations to solve traffic operational problems and/or to improve traffic flow. The Consultant's analysis shall be based on County, State, and Federal policies and regulations, guidelines in the Traffic Operations and Safety Analysis Manual, and accepted engineering principles and practices. The Consultants shall employ, as necessary, updated traffic engineering tools, such as computer simulation models with software tools, such as Synchro/SimTraffic, Sidra, VISSIM, Transmodeler, Corsim, HCS, etc. to complete this work. Work may require extensive traffic data collection, to include but is not limited to, speed, volume, classification, turning movements, travel time, delay, pedestrian counts, and bicycle counts. Expertise in Macro/Mesoscopic software, such as CUBE, shall be required for planning level and large area modeling. B. Traffic, Safety, and Operational Studies Work may include the collection/review of various types of data, to include crash, speed, traffic volume, vehicle probe, roadway/asset inventory, alignment, and design data, as well as the performance of operational and safety analyses. The consultant shall be able to perform and utilize the methodologies outlined within the Transportation Review Board (TRB) Highway Capacity and the American Association of State Highway Transportation Officials (AASHTO) Highway Safety Manuals, to include any related analysis and design software. Work may include field investigations, research, analysis, summarization, and/or recommendations regarding the specific issue(s) being reviewed and studied, cost estimates (including costs for preliminary engineering, right of way, utility relocation, and construction phase costs), and the formal presentation of the results to the public and/or elected officials. Work may also include the analysis of traffic and pedestrian data (directional flow volumes, crash statistics, and/or speed samples), and the application of this data into Signal Justification Reports as outlined in the Virginia Department of Transportation (VDOT) Traffic Engineering Memorandum 387.1, Manual on Uniform Traffic Control Devices for Streets and Highways (MUTCD), and the Institute of Transportation Engineering (ITE) Manual of Transportation Engineering Studies. Experience with the VDOT Junction Screening Tool (VJuST) is desirable. Depending upon the specific project, public information meetings and interaction may be required. All inquiries and technical questions or comments related to this solicitation shall be directed to John Bishop no later than Friday, September 27, 2024, 2:00 p.m., local time.
