1. INTRODUCTION

As required by 23 U.S.C. § 166, the California Department of Transportation (Caltrans) prepared the 2018 California High-Occupancy Vehicle Facilities Degradation Report to report the performance of the high-occupancy vehicle (HOV) facilities in California. Caltrans also prepared an action plan that identified remediation strategies to bring degraded HOV lanes into compliance with federal performance standard.

An HOV facility is a preferential facility designated for exclusive use by vehicles with two or more occupants for all or part of a day. Federal law authorizes states to allow inherently low-emission vehicles (ILEVs), certain gasoline/electric plug-in hybrid vehicles, and toll-paying vehicles to access HOV facilities without meeting occupancy requirements. States that allow these exempted vehicles to access HOV facilities must monitor and report the performance of those HOV facilities.

California allows certain Inherently Low Emission Vehicles (ILEVs) and Plug-in Hybrid vehicles displaying valid Clean Air Vehicle (CAV) decals to access HOV facilities without meeting occupancy requirements.1 The California Department of Motor Vehicles (DMV) administers the clean air vehicle decal program. As of December 31, 2017, the DMV issued 166,873 white decals for ILEVs and 136,753 green decals for Plug-in Hybrid vehicles. Starting in 2018, the DMV created a new red decal for all types of qualifying clean air vehicles. Green and white decals remained valid through the end of 2018. By December 31, 2018, the DMV had issued 441,011 red decals. The statewide distribution of decal registrations, by county, is available in the Appendix, tables A-1 and A-2. California also allows toll-paying vehicles not meeting occupancy requirements to access certain HOV facilities known as high-occupancy/toll (HOT) or express lane facilities.2 The California Highway Patrol (CHP) enforces HOV facilities restrictions.

In accordance with the federal law, Caltrans established a performance monitoring, evaluation, and reporting program for the HOV facilities. In addition to existing remediation actions currently in progress or scheduled for implementation, Caltrans is collaborating with the Federal Highway Administration (FHWA) and partner state and regional transportation agencies to identify additional strategies. In the future, Caltrans may consider requesting a waiver for certain HOV facilities from compliance with degradation requirements.

2. DEGRADATION DETERMINATION METHODOLOGY

Federal law considers an HOV facility as degraded if the average traffic speed during the morning or evening weekday peak commute hour is less than 45 miles per hour (mph) for more than 10 percent of the time over a consecutive 180-day period. Previous degradation reports have consistently identified more lane-miles of degraded HOV facilities in the second half of the calendar year than the first half. While Caltrans continues to monitor the HOV facilities for the entire year, Caltrans and FHWA agreed degradation report and action plan would focus on the second 180-day period of the year, from July 1 to December 31.

Caltrans uses the Performance Measurement System (PeMS) software tool to monitor and analyze the operational performance of the state highways. PeMS serves as a central repository to collect, store, and analyze traffic data from sources such as vehicle detectors and traffic census stations. PeMS reports operational information such as traffic speeds and volumes. Caltrans analyzes weekday data, including holidays that fall on weekdays, but not weekend data because the federal standard only applies to weekdays.

The data analysis is as follows:

 Each HOV facility is divided into segments. The average speed for each segment during the morning and afternoon peak periods is collected for each weekday.

 Weekdays for each segment are identified as degraded when either the morning or evening peak hour(s) average speed is less than 45 mph.

 A segment is considered degraded when more than 10 percent of its weekdays out of the total monitored weekdays in the analysis period were degraded.

For 2018 there were three significant changes to the data analysis process:

 Historically, speed data was only collected for one hour in the morning (8 a.m. to 9 a.m.) and one hour in the afternoon (5 p.m. to 6 p.m.). These single-hour peak periods were selected based on the fact they capture the peak travel times in most areas of the State. For 2018, a decision was made to expand the peak hour periods to three hours, 6-9 a.m., and 3-6 p.m. HOV facilities in districts 3, 7, 8, 10, 11, and 12 were analyzed for these expanded three-hour peak periods. District 4 was only analyzed for the 8-9 a.m., and 5-6 p.m. single-hour peak periods due to limitations of PeMS that would not permit such analysis. Improvements are being made to PeMS that will allow for the expanded three-hour peak analyses for all districts starting in 2019.

 Historically, each HOV facility has been divided into segments approximately five miles in length; however, all districts, except for Districts 4 and 11, redefined their segments to more accurately capture traffic flow conditions along their HOV facilities. Segments were re-defined by beginning and ending at interchange locations rather than using equidistant sections regardless of where intersecting routes occur.

 District 11 (San Diego Area) had previously noted that they had some issues with PeMS not reporting average speeds for the reversible flow Interstate 15 High-Occupancy Toll facility. For this report, they used the Ramp Meter Information System (RMIS) to collect accurate speed data for Interstate 15 as well as their other HOV facilities. The RMIS data was compared against the PeMS data. District 11 staff determined the data was similar on all corridors except for the I-15 due to the reversible express lanes. The RMIS data may be used for District 11 in future reports.

Many variables can affect traffic flow in HOV facilities. While the federal standard distinguishes HOV facilities' performance as degraded or not degraded, Caltrans further classifies degradation into three categories to extrapolate potential causes and formulate remediation strategies. The criteria for each category of degradation status are as follows:

0. No Data (data collection infrastructure not available to track traffic speeds). 1. Not Degraded—degradation occurs less than 10 percent of the time, or two or less weekdays per month. 2. Slightly Degraded—degradation occurs from 10 to 49 percent of the time, or three to nine weekdays per month. 3. Very Degraded—degradation occurs from 50 to 74 percent of the time, or ten to 15 weekdays per month. 4. Extremely Degraded—degradation occurs 75 percent or more of the time, or 16 or more weekdays per month.

These criteria are referred to in footnote #3 on pages 12 through 77, and in Table A-3 (pages 80 through 89).

3. STATEWIDE DEGRADATION SUMMARY AND ACTION PLAN

In 2018, Caltrans operated 1,790 lane-miles of HOV facilities on the state highway system. Monitoring data was available for 1,581 lane-miles of HOV facilities. Degradation data was not available for 168 lane-miles due to vehicle detector upgrades and repairs. The State Route 91 express lanes facility in Orange County does not require reporting degradation in compliance with 23 U.S.C. §166 because it was originally authorized under 23 U.S.C. §129. This facility is considered “Monitor only” and its degradation status is not reported in this document.

Table 1 summarizes the statewide HOV facilities degradation monitoring in 2018. Figure 1 shows the lane-miles of degraded HOV facilities by district. Of the 1,581 lane- miles monitored, forty-seven percent (744 lane-miles) was considered degraded. Figure 2 shows statewide degradation further categorized as slightly degraded, very degraded, and extremely degraded. Forty-two percent of the degraded HOV facilities statewide was slightly degraded (309 of 744 total degraded lane-miles). Twenty-seven percent was very degraded (200 of 744 total degraded lane-miles). Thirty-two percent was extremely degraded (235 of 744 total degraded lane-miles).

For each district, degraded HOV facilities are reported in a table and map. Degraded HOV facilities listed in the table may include some non-degraded segments.

Caltrans collaborated with the FHWA, the CHP, and other stakeholders to establish a Managed Lane Working Group (ML Working Group). The ML Working Group develops and supports the implementation of strategies to optimize the performance of the HOV facilities. Table 2 presents an initial list of strategies identified by the ML Working Group to remediate degradation. The ML Working Group will continue assessing and updating the list to incorporate new lessons learned and advancements in the state-of-practice for traffic demand management. These task references are also noted in the individual action plans for each degraded HOV facility, wherever they are proposed.

Caltrans is committed to implementing the strategies presented by the ML Working Group. For each degraded HOV facility, Caltrans will correlate existing actions that have been implemented to the list of strategies and assess the feasibility of other strategies on the list for initiation. As a part of this effort, Caltrans will review local traffic data and field conditions to identify potential causes of degradation and determine viable strategies to remediate those causes. Analysis suggested factors contributing to degradation include:

 Recurrent congestion on the freeway  Disruptions to the traffic flow from vehicles entering or exiting the HOV facility  Congestion at the downstream end of the HOV facility backing up traffic into the HOV facility  HOV demand exceeding the capacity of the Managed Lane

Caltrans has already initiated various minor and major infrastructure projects to improve the performance of HOV facilities. Some projects were underway in 2018, while others will begin construction within the next several years. Caltrans will assess the effectiveness of these improvements at reducing HOV facilities degradation upon completion of the projects and after traffic patterns have normalized. Caltrans is also implementing active traffic management and traffic demand management strategies to mitigate congestion on freeways in some districts. These strategies include on-ramp and freeway connector ramp metering, adaptive ramp metering, integrated corridor management, and speed harmonization to optimize traffic flow on the freeway and local arterials and minimize stop-and-go conditions.

Caltrans may consider increasing minimum occupancy requirements for certain HOV facilities to remediate degradation. Prior to making such operational change, Caltrans would need to thoroughly examine the effects the change may have on the HOV facility and entire freeway facility. The analysis would consider the geographic, geometric, and traffic demand characteristics of both the individual freeway facility and the region. To minimize traffic impacts, increasing occupancy requirements could be accomplished in conjunction with conversion of the HOV facilities to HOT/express lanes to efficiently manage traffic demands. HOT and express lanes allow additional flexibility in traffic demand management of the lanes by actively controlling the access of eligible vehicles. Caltrans is in the process of developing guidance on when to

© 2020 California Department of Transportation. All Rights Reserved. 6 2018 California High-Occupancy Vehicle Facilities Degradation Report and Action Plan September 2020 consider and how to implement changes to vehicle occupancy requirements. That guidance should be completed in the fall of 2020.

Currently, Caltrans is not considering prohibiting exempted clean air vehicles (CAV) from HOV facilities. Caltrans will continue conducting traffic counts to determine the distributions of vehicle occupancy and classifications, including exempted vehicles.

Vehicle occupancy counts also help to identify locations with high numbers of ineligible vehicles in the HOV facilities. Caltrans will share this information with the CHP, so they can prioritize their enforcement efforts and effectively deploy their enforcement efforts. One such location is the Interstate 80 corridor in District 4, between the Carquinez Bridge and the San Francisco-Oakland Bay Bridge. The Metropolitan Transportation Commission (MTC) recently agreed to fund the CHP for three years, beginning in July 2018, for enhanced HOV enforcement along this corridor. Caltrans will support this effort by updating the HOV violation fine amount on existing signs along the freeway to the current value. Caltrans and the MTC will collect traffic data to analyze the performance of the HOV facilities and across the entire freeway facility during the enhanced HOV enforcement time period. Additionally, the Golden Gate Division of the CHP in District 4 has also begun increasing HOV enforcement on freeways within their jurisdiction. Because of these enhanced HOV enforcement efforts, the CHP is recording an increase in the number of citations issued for HOV violation. Caltrans conducted some limited “before and after” studies of a couple of HOV facilities where enhanced enforcement occurred and found there was no significant impact on degradation. More information will be included in future reports. CHP’s enhanced enforcement effort is concentrated on the HOV lanes.

Caltrans has ongoing projects in all districts to improve the overall health of Transportation System Management (TMS) detection, and, quality of data to collect degradation information.

The Managed Lanes Study will produce a Concept of Operations for the corridor with possible solutions for HOV degradation and help identify engagement activities with CHP and other stakeholders. • D3 has identified several ramp metering issues along the northbound (NB) SR-99 corridor associated with unmetered HOV Preferential Lanes (HOVPL). Recent ramp count data shows HOVPLs violation rates of over 60%, which greatly impact the effectiveness of the ramp meters along this corridor. Recently, D3 implemented its first HOVPL metering in this segment of SR-99 (Mack Road Slip) and observed improvements in segment travel times across all lanes (roughly 4%). D3 is currently initiating projects to meter all five (5) unmetered HOVPLs in this segment, along with adding additional Intelligent Transportation System elements to help improve traveler information and incident response. Funding options for the ramp-metering improvements include applying for 2020 Sacramento Area Council of Governments Regional Flexible Funding Programs and the 310/315 Minor Program. This project will also help improve the Corridor Ramp Metering system already in operation. (Continued next page)

(SR-51 & SR-99 continued from prior page)

• For northbound SR-99 a project will be going to construction in 2022 that will meter the HOVPL’s at the Florin slip on-ramp and at both on-ramps from 47th Avenue to northbound SR-99. • During the a.m. peak period on northbound SR-99, D3 is using a Coordinated Adaptive Ramp Metering (CARM) strategy developed by UC Berkeley PATH. Initial results in 2016, showed an average increase in speed of 7.25% during the a.m. peak hour. UC Berkeley PATH is currently working on a Graphic User Interface for their CARM algorithm which would give D3 the ability to implement the CARM on other corridors, specifically southbound SR-99 for the p.m. peak commuter period. • In the southbound direction D3 activated 15 new ramp meters along this corridor in November 2019. D3 is also conducting a before and after study to evaluate the impact of new ramp meter activation on degraded HOV lanes. The study was scheduled to be completed by June 2020 and results will be shared with FHWA; however, with traffic anomalies due to the COVID-19 emergency and the Stay Home – Stay Safe order in the earlier months of 2020, the study will be delayed several months until traffic normalizes, and typical peak traffic data collection can be conducted to provide representative “After” condition. • Vehicle occupancy count data and HOV violation rates will be shared with the CHP to help prioritize HOV occupancy enforcement efforts on freeway corridors and segments identified as degraded. Caltrans D3 and CHP at the Lieutenant and Captain level have had multiple discussions on areas of congestion and optimizing enforcement for SR-99. These discussions have specifically prioritized SR-99 HOV lane enforcement due to the high violation rate observed, and degradation on the corridor.

Traffic moving at 65 mph next to the stopped GP lanes has not been observed. Speeds in the express lanes did increase with addition of channelizers because motorists felt more comfortable with the speed differential with a channelizer separation. • The occupancy violation rate with the self-declaring FasTrak flex transponder has increased over time, as motorists became aware that they could ride toll-free by simply switching the transponder on 2 or 3. The automatic vehicle occupancy detection system (AVODS) to be implemented in June of 2020 should reduce this average 30% violation rate over the peak period and 60% violation rate in the peak hour.

(SR-91 continued from prior page)

• District 12 conducted and completed the I-5 Managed Lane Project Study Report in 2019 which will help SR-91 degradation as a system integration solution. (O3, O13) • The MLNS study recommends two (2) different alternatives to address HOV degradation in both directions of SR-91 between I-5 and SR-55. The two alternatives are: 1) convert the existing HOV lanes to HOT lanes (one existing lane in each direction), or 2) add another managed lane, and operating both lanes as HOT lanes (two lanes in each direction). The MLNS also recommends that the SR-91 improvement project move forward in the project development process, and complete construction by 2030 or earlier. (C1, O3, O13) • District 12 continues to collaborate with our regional partner, Orange County Transportation Authority, to evaluate the MLNS alternatives, as well as, opportunities to mitigate the degradation of the EB SR-91 HOV lane transition to the EB Express Lane entrance.
