![]() The New American Legion Bridge I-270 to I-70 Traffic Relief Plan will address long-term growth throughout the region. ![]() The ICM Project is aimed at helping improve today’s congestion by eliminating existing bottlenecks and adding intelligent traffic system that will improve reliability and predictability for today’s users. The I-270 ICM Project is separate from the New American Legion Bridge I-270 to I-70 Traffic Relief Plan. In addition to the 23 southbound I-270 ramps being activated this week, MDOT SHA plans to install ramp metering on another 22 ramps onto northbound I-270 in 2022, for a total of 45 ramps at 18 interchanges by the end of next year. Other elements of the overall $132 million I-270 ICM Project include additional auxiliary lanes between interchanges, extension of acceleration and deceleration lanes and reconfiguration and restriping of existing lanes to optimize traffic operations. Ramp metering is one piece of the I-270 ICM Project that Governor Larry Hogan announced in 2016 to provide congestion relief and improve travel times throughout the 34.4-mile I-270 corridor from I-70 to I-495. While a first for Maryland, ramp meters have been used elsewhere as a proven, cost-effective tool to help improve safety and efficiency and reduce congestion. For more information and to view a location map and ramp metering video, click The system also detects the length of vehicles in queue to help ensure ramps don’t back up onto arterial roadways. Motorists are advised to use caution and reduce their speeds approaching the traffic signal, as there may be stopped vehicles waiting to merge onto the highway. When ramp metering is not in operation, beacons will be dark and the traffic signals will flash yellow, allowing motorists to proceed without stopping. Once the signal turns green, a driver may proceed and merge onto the highway one vehicle at a time. When ramp metering is in full operation, motorists will see a warning sign with flashing beacons and should slow down, watch for queued vehicles and be prepared to stop at the stop line just prior to the highway entrance. Signals at the end of the ramps have been flashing yellow for about a month to alert motorists that activation of ramp metering is coming. daily and are anticipated to be active during peak traffic hours and when I-270 experiences traffic congestion. The ramp metering signals will have the capability to operate between 4 a.m. The system balances highway demand and capacity, maintains optimal highway operation and reduces congestion for safer, more efficient travel. Ramp metering uses traffic signals and sensors to manage traffic flow entering the highway. I-270 Innovative Congestion Management (ICM) project to help improve safety, reduce congestion and save drivers up to 30 minutes on their morning commute between Frederick and I-495 (Capital Beltway). (September 9, 2021) – The Maryland Department of Transportation State Highway Administration (MDOT SHA) will fully activate new ramp meters on 23 ramps to southbound I-270 in Frederick and Montgomery counties Wednesday, September 15, weather permitting. BCC also handled modification to controller software for ramp metering operations.System to Operate on 23 Southbound Ramps at 18 Interchanges The Signalization Scope included reconstruction of existing signals at Broward Blvd ramp terminals and a new Signal in the Broward Blvd Park and Ride Facility.Īs the ITS Engineer for the project, the Team provided design services for Fiber Optic Cabling along length of project, Microwave Vehicle Detection Systems (MVDS), Closed Circuit Television (CCTV), Dynamic Message Signs (DMS), Advanced Distribution Management System (ADMS), Tolling DMS, Ramp Metering, Wrong Way Detection, and Generator backed power subsystems.Also signing and markings at Broward Boulevard and Broward Blvd. Signing and Pavement Markings design was developed for 6.53 miles along I-95 encompassing express lanes ingress and egress connections and 5 interchanges connections.Group provided design and construction support service for S&PM and Signalization: Phase 3A-1 of the 95 Express program consists in converting the existing High Occupancy Vehicle (HOV) lanes to High Occupancy Toll (HOT) lanes, as well as one lane widening in each direction, resulting in two tolled Express Lanes in each direction from south of Broward Boulevard to north of Commercial Boulevard in Broward County.īCC Engineering is the prime Design Project Manager.
