ATM Project Database

ADOT is planning, designing and implementing an ATM system for the I-17 corridor in metro Phoenix. This is a corridor through a highly developed area, so there is not an opportunity for expanding travel lanes. ConOps is focusing on Dynamic Speed Limits, adaptive ramp metering, and LCS. Corridor currently has HOV in place. As of 8/2015, ConOps is in development. Examined shoulder running, but too many constraints with HOV, very limited shoulder on many parts of I-17, and auxiliary lanes.

The ramp metering plan for southbound I-680 uses a real-time adaptive system that monitors traffic volumes and density and adjusts the ramp metering rate based on thresholds that vary by time of day set for the travel demand at each ramp.

The main objective of the I-210 Connected Corridors/Congsestion Relief Project is to better regulate vehicle flow upon entering the freeway system. This is being accomplished with advanced metering equipment and technology for use with on-ramp meters, freeway-to-freeway connector meters, dynamic rerouting and HOV Bypass Lane metering. This is the first Caltrans lead ICM effort. It involves 4 cities, the county of LA, LA Metro, Caltrans and UC Berkeley PATH.

The system used underground sensors to count vehicles entering and exiting the parking area’s reserve lot. The data collected were relayed to a central computer system where vehicle counts were processed and information on parking availability was posted on an Internet website and displayed on two portable dynamic message signs (DMS) located on Highway 24.

Utilizes congestion management pricing to establish tolls for the 91 express lanes. The express lane allows groups of three or more commuters travel for free or at a discount during certain hours.

Use of dynamic lane markers for junction control to provide a connector lane during peak hours to I-5 Northbound. Implemented in 2010; currently being upgraded.

SANDAG is examining potential ATDM strategies for the I-805 corridor in metro San Diego. Key issues are transit and freight mobility. Looking to leverage lessons learned from the I-15 ICM.

The I-680 Express Lane gives solo drivers the choice to pay a toll electronically to use the lane while regular carpool users continue to use the lane for free.

The I-880 Express Lane gives solo drivers the choice to pay a toll electronically to use the lane while regular carpool users continue to use the lane for free. To open in 2019

SFpark is a demand-responsive parking pricing and management system. The pilot effort provides real-time parking availability information for on- and off-street parking and also incrementally raises or lowers parking prices based on demand to maintain a minimum level of parking availability

VTA converted existing HOV lanes on SR 237/I-880 to HOT lanes providing solo drivers the opportunity to use the express lanes for a fee using FasTrack electronic toll collection technology.

This project will convert 34 miles of existing High Occupancy Vehicle (HOV or carpool) lanes to express lanes from Dunne Avenue in Morgan Hill to the San Mateo County line. Carpools with two or more occupants, motorcycles, transit buses, and eligible hybrids will continue to use the express lanes free of charge. Solo drivers will have the option of paying a toll to use the express lanes during commute hours.

A regular Stanford commuter, will earn credits when they enter and exit the main Stanford University campus by car at designated off-peak hours Monday through Friday. Credits can be used to win random cash rewards from $2 to $50 over and over again on the Capri website. The rewards accumulated on Capri will be disbursed monthly via Stanford's payroll or through bank deposits.

The ATM system is expected to incorporate variable speed limits based on advanced algorithms to improve traffic turbulence in real-time, reduce crash risk, and improve traffic flow.

Use of VSL and Lane control for travel on the Delaware Memorial Bridge as part of Advanced Traffic Management System

The Cape Coral Bridge is composed of two fixed spans approximately 3400 feet long with a vertical clearance of 55 feet above the Caloosahatchee channel and a width of 95 feet clearance for the center channel.

The toll facility though small in size, has three traffic toll lanes that process on average over three million vehicles annually. All three traffic lanes flow in a Westerly Direction towards Sanibel Island. Two traffic lanes are designated for patrons who need change and or receipts for payment of tolls and one traffic lane dedicated to Electronic Toll Collection.

One of the U.S airports that has seen the widest application of advanced parking management systems.

ParkPGH provides real-time information on available parking. An application, website, and call-in phone number all allow travelers to get current information on the number of available spaces in all nearby garages, with data updated each minute through a feed from the gate system at each garage.

Manged Lanes. Gives solo drivers the opportunity to use HOV lanes for a toll

In November 2000 the Northwest Freeway HOV lane was converted to HOT use, and is operated in a manner similar to the Katy Freeway. The Northwest QuickRide allows paying two-plus carpools to use the lane only in the morning peak when three-plus occupancy requirements are in effect.

Parking prices are based on events, and intervals between trains reduced during major events when demand is high

The segment of I-66 between U.S. 50 and I-495, where the case study HOV/shoulder lane combination is operational, includes three main lanes in each direction. Starting in 1992, the shoulder was opened to peak-period, peak-direction general purpose traffic, allowing the leftmost lane to operate as an HOV lane. With completion of an ATM project in the fall of 2015, VDOT will implement dynamic lane control, hard shoulder running, queue warning and ultimately variable speed limits.

This 1.5-mile project allows traffic to travel on the left shoulder of northbound I-495 from where the 495 Express Lanes end to the George Washington Parkway.

An 11-mile segment of I-64 along Afton Mountain recently had ITS assets and communications infrastructure installed that will allow for the future installation of Variable Speed Limit signs during reduced visibility conditions.

The traveler information center TIC integrated phone and paging technology to deliver three types of personal commuter information: (1) dynamic ride matching information, (2) current traffic congestion information, and (3) transit information.

WSDOT has looked at a range of options to address the projected increase in population and employment along this corridor. Studies acknowledge the importance of connecting I-405 and SR 167 to form a seamless corridor. The Eastside Corridor (made up of sections of Snohomish, King and Pierce counties, stretching down I-405 and SR 167 to SR 512) vision includes new highway lanes, improved interchanges, express toll lanes, expanded transit service including bus rapid transit (BRT) and expanded vanpool programs

e-Park uses dynamic message signs to direct users to parking garages with remaining capacity. Current garage capacity can be viewed on a mobile-friendly website for 12 parking garages.

The signs post variable speed limits that help warn drivers of backups ahead and smooth out traffic as it approaches a lane blocking incident. The overhead signs can also quickly close entire lanes and provide warning information to drivers before they reach slower traffic.

This system consists of 15 overhead mounted Flip-disc and LED signs. The speed limit is based on traction requirements, pavement conditions, visibility, weather (precipitation amount and type), and incident types. There are thresholds for the system, and the speed limit is based on a matrix of the conditions given above.
