Signal Design. Stantec will design and prepare signal plans and electrical details for traffic signal upgrades to the three subject intersections to add the new pedestrian facilities. The existing poles, junction boxes, vehicular signal heads, cabinet, and controller will be retained. Existing detection will be re-used except in cases where the stopbar is moved, and stopbar detection is present or necessary. Scope of signal work will include the preparation of Traffic Signal Plans, Electrical and Programming Details, Project Special Provisions, and Signal Equipment Quantities. These plans shall be prepared in accordance with the current design standards of the NCDOT Transportation Systems Management & Operations Unit. Stantec will obtain the latest signal plans and electrical details from NCDOT and incorporate all the necessary design information required to upgrade them to current standards as part of the proposed project improvements. Stantec will use the current signal plan for basemapping and update with any revised information resulting from topo survey or field review. We will show the new and revised pedestrian crossings, curb cuts, and sidewalk on the signal plans. Stantec will coordinate all signal plan submittals, reviews, and design issues with the Town, NCDOT Division 5 and Transportation Systems Management & Operations Unit as appropriate. Stantec signals staff will perform very basic dry utility coordination for minor conflicts between signal guy wires/ signal span wire and proposed sidewalk or curb ramps. For final approval, all traffic signal plans and associated design material and specifications shall be reviewed and accepted by the NCDOT- Transportation Systems Management & Operations Unit. Stantec will prepare a 90% submittal of signal and electrical plans to be submitted with the 90% roadway plans if not sooner. This will be the only preliminary submittal before the 100% submittal. Quantities and any necessary Special Provisions will be included with both submittals. The scope for the signal plans will include a site or google-street-view inventory of existing signal equipment, as well as up to 2 virtual meetings to discuss signal-related issues. It is assumed that no signal communication infrastructure will be impacted by this project. If signal communication design is determined to be required by the Town, then the consultant will coordinate with the Town on the scope, fee, and schedule adjustments as necessary of the project.
Signal Design. The CONSULTANT will design the modernization/upgrade of two signals within the project limits. The existing traffic signals at Cragmont Street and Mill Street along Main Street will both be replaced as part of this project. Traffic Counts will be obtained utilizing Miovision Cameras and will be projected to the future year. Classifications, including pedestrians, will be obtained from these counts in order to design pedestrian clearance intervals.
Signal Design. CONSULTANT will develop a preliminary proposed signal design based on current MUTCD and Region 4 requirements. It is assumed all traffic signals will be replaced and the new poles will be placed in a location where the current signals can still operate during construction of new infrastructure. The preliminary signal design will include poles, heads, detection, pedestrian buttons and signals, new controller and its location and emergency vehicle preemption.
Signal Design. A Professional Engineer of the firm shall be in responsible charge for the design of a traffic signal at the intersection. The signal plan sheet is to include but not limited to signal operating plan, controller assembly, controller timings, loops, loop lead-ins, conduit, pole schedule, signal head details, signing and pavement marking, pole location rod readings, a rod reading for the high point of the road and a summary of pay items. The CONSULTANT is responsible for all signal pole calculations using an approved FDOT structural software. The output shall be provided to the DEPARTMENT for all signal pole designs. Sub Task 1A: Pedestrian Features The traffic signal design is to include pedestrian features.
Signal Design. This task includes development of traffic signal modification plans for the NE Olney Avenue/NW Wall Street intersection. Work performed under this section shall be done according to the requirements of the ODOT Traffic Signal Design Manual, ODOT Traffic Manual, applicable Oregon Standard Drawings, and City of Bend standards. All traffic control devices installed in the state of Oregon are required to conform to the Manual on Uniform Traffic Control Devices (“MUTCD”) and the Oregon Supplements as to the MUTCD as established by ORS 810.200 and OAR 734-020-0005. Assumptions: ▪ No existing traffic signal mast poles will be impacted ▪ Structural analysis of signal pole mast arms will be assessed if changing the loading along the mast arms ▪ Up to one (1) field visit with ODOT signal staff to investigate status of junction boxes, conduit, traffic signal equipment, etc. is included. ▪ No temporary traffic signal plans will be prepared. If existing pushbuttons cannot remain active during construction, recall mode will be utilized. ▪ Cabinet print reflecting signal modifications will be prepared. Agency will provide existing cabinet print information. ▪ Signal interconnect between the BNSF railroad bungalow and the traffic signal will not be provided ▪ ODOT preliminary signal operations design form will be completed to document any phase or lane changes ▪ Signal Plans include: Traffic Signal Legend (1), Traffic Signal Modification Plan (1), Existing Utilities Plan (1), Pole Entrance Chart Plan (1), Detail Sheets (2), Cabinet print (1), PSOD (1)
