Background The purpose of this presentation is to provide an update on the traffic signal system network. Much of the recent focus on the traffic signal system has been specific to network upgrades that would increase traffic signal data efficiency throughput and increase system security, while also eliminating the occurrence of network outages experienced at the Traffic Management Center, or TMC. The presentation will also provide an overview of signal operations at El Camino Real & Arenal Road during emergency vehicle preemption as well as protected- permissive operations of a Flashing Yellow Arrow, or FYA, signal. Discussion Traffic Signal Communications Network When initially established, the city traffic signal communications network was comprised of a combination of wireless radio and copper hardwire connections. All traffic signals that were in communication with the TMC, were connected to a larger aggregated signal group that passed through one or two wireless and solar repeaters. As the city upgraded its signal controller technology, these repeaters became a constriction that could not allow all controllers to transmit real-time traffic signal information. Before the Carlsbad Digital Information Network, or CDIN, was established, several departments transmitted their data between their central servers and field equipment on independent networks, including the traffic signal system, utilities, police, etc. With the recent implementation of the CDIN, the city’s Information Technology, or IT, Department has focused on integration and upgrade of the various networks that were previously stand-alone. A major feature of the CDIN is the utilization of fiber-optic communication technology to increase data throughput and reliability. Oct. 2, 2023 Item #3 Page 1 of 3 The following traffic communication network upgrades have been completed to improve traffic signal system functionality and reliability: •Connected the Aviara Park wireless repeater to a nearby park facility on fiber. This eliminated the need to transmit to the Crossings golf course via wireless and solar repeater. All signals transmitting to Aviara Park now return to the TMC on last leg fiber. •Removed the wireless and solar repeater from the golf course and replaced with new equipment now located at the Crossings golf course clubhouse. The clubhouse equipment is on direct power. Since the clubhouse is on fiber, all signals transmitting to the golf course now return to the TMC on last leg fiber. •Redirected several traffic signal groups away from longer wireless connections to Aviara Park or Crossing golf course repeaters to closer fiber connections. •Migrated the server for the traffic signal central software system. This included creation of new virtual servers with updated operating systems to improve performance and increase security. •Migrated Bluetooth reader devices to the new network. •Rebuilt the video detection software viewer and moved devices to the new network. •Reconfigured traffic signal and video detection devices from the legacy IP settings to the current CDIN network settings. This improved performance and increased security. Other projects either underway or identified as potential network improvement project are described below: •Interim cellular connections are being established for all traffic signal locations previously offline due to the line-of-sight limitations. The cellular connections will be replaced as future connections are established via high-speed wireless or fiber. •The city is actively exploring opportunities to partner with residential fiber providers to upgrade existing copper hardwire connections to fiber between traffic signals where conduit exists. •The city is actively exploring opportunities to bring back additional traffic signals on fiber that are not in proximity to the current CDIN backbone. Traffic Signal Operations The communication network upgrades have allowed staff to fully utilize functionality of both the traffic signal central software and the upgraded traffic controllers in the field. The following tasks have been completed or are in process related to signal operations: •Signal coordination timing is in operation for the morning and evening peak periods on El Camino Real, Palomar Airport Road, and Rancho Santa Fe Road. Use of midday coordination is under consideration. •Carlsbad Village Drive, west of Interstate 5, or I-5, is currently running coordination timing offset from the I-5/Carlsbad Village Drive northbound on/off-ramp signal. Caltrans has updated their own central system and controllers which now keeps their signal clocks current, making coordination possible. Oct. 2, 2023 Item #3 Page 2 of 3 •El Camino Real, in the vicinity of State Route 78, or SR-78, Plaza Drive to Carlsbad Village Drive, is currently running coordination timing offset from the SR-78 eastbound on/off- ramp signal. City of Oceanside signals to the north of SR-78 are also working from the same Caltrans offset. City of Oceanside recently upgraded its controller at El Camino Real/Vista Way due to periodic malfunctions. The previous controller was not consistently maintaining current time settings and would exacerbate traffic flow conditions on the El Camino Real corridor during peak and saturated conditions. •Staff is evaluating use of coordination timing on other corridors and/or intersections groups. •The traffic signal central system software, ATMS.now, was recently updated from v2.12 to v2.14. This is expected to address several bugs reported to the developer by city staff, including the copy/paste grid function, and pedestrian displays on real-time scan, etc. •Traffic signal controllers are currently running the Cubic Scout system with firmware ranging from v80.4.2 to v85.3. With the rollout of the new ATMS.now, staff is testing the stability and functionality of each version before considering upgrade of all devices to the most up to date v85.x. •Network communications upgrades have allowed real-time alerts to function more reliably, e.g., notification when a signal goes into all-way flashing red operations, when a signal controller is accessed, etc. •Alert configurations are being evaluated to notify during missed detection and false detection events. •Bluetooth reader device settings are being reconfigured to provide more usable vehicle feedback. •Big data analytics platform is being tested to view historical travel patterns and other data insights. •Detection upgrades on primary corridors is being evaluated. The city’s predominant detection system has been discontinued by the manufacturer and spare components are no longer commercially available. As primary corridors are upgraded, components that are removed can be reused elsewhere or kept for spares. The presentation also provides an overview of the following traffic signal operations: •El Camino Real/Arenal Road phase sequencing during emergency vehicle preemption, including issues previously identified and corrected. •FYA protected-permissive left turn operations. A new traffic signal using FYA will be constructed as part of the conditions of approval for a new Chick-fil-A restaurant on the 5900 block of Avenida Encinas. Next Steps Staff will continue to work in close coordination with the IT Department to improve the traffic signal communication network, with the purpose of using signal controller and central system technologies to optimize traffic flow within the city.
