310 CMR 7.37
MB High Occupancy Vehicle Lanes
(1) Definitions. As used in 310 CMR 7.37:
BASELINE ROADWAY CONDITIONS means the average weekday peak hour trip time in
minutes for each roadway segment based on monitoring of traffic and recording of trip times
during the 12 month period from April 1, 1992 to April 1, 1993.
FEASIBILITY STUDY means a study which analyzes the environmental, operational,
engineering, right-of-way, construction, and financial issues affecting the implementation of high
occupancy vehicle lanes on each roadway segment described in 310 CMR 7.37(3). The analysis
of environmental issues shall include the impacts of HOV lanes on all mobile source emissions
of CO, VOC and NOX as well as the impacts of such lanes on general purpose traffic flow.
Operational issues may include enforcement and public safety issues. Notwithstanding the
foregoing, in cases in which feasibility studies submitted to the Department on or before
November 1, 1994 have not included an analysis of the impact of HOV lanes on NOx emissions,
an analysis of such impacts will be submitted to the Department for inclusion in the
Transportation Improvement Program for the metropolitan Boston area, as required by 23 CFR
450.
FINANCIAL as used in 310 CMR 7.37(1) and 7.37(8)(a) means the availability of funds from
any federal, state or local sources for the design and construction of a high occupancy vehicle
lane or facility.
PERFORMANCE STANDARDS means a level of roadway performance that at a minimum: 1.
is equal to or better than a Level of Service C, and 2. will result in average HOV trip times that
are at least one minute per mile less than average trip times on adjacent general purpose traffic
lanes during peak hours of travel, as defined in 310 CMR 7.37(6)(b)2. Either the MHD or the
MTA may propose substitute roadway performance standards which attempt to maximize: travel
time savings, reductions in emissions of ozone precursors, operational efficiency, and person
throughput, and which require vehicle throughput of no less than 400 HOVs per hour for a high
occupancy vehicle lane provided that such standard provides for greater improvement in air
quality for VOC, CO and NOX in the area where the HOV lane is targeted, in both the short and
long term. The Department shall review any proposed substitute roadway performance standard,
and shall either reject or accept it within 60 days after it has been submitted to the Department.
ROADWAY THRESHOLD STANDARDS means Baseline Roadway Conditions increased by
35%.
(2) Applicability. 310 CMR 7.37 applies where indicated, to the Executive Office of
Transportation and Construction (EOTC), the Massachusetts Highway Department (MHD), and
the Massachusetts Turnpike Authority (MTA).

within 30 days from the date of the Federal Highway Administration issuance of a Record
of Decision in connection with said review.
(c) By June 30, 1994, the MTA shall submit to the Department a study of the feasibility of
establishing high occupancy vehicle lanes for Interstate-90 eastbound and westbound
between Interstate-93 and Interstate-95. Said study shall include analyses of the feasibility
of:
1. Implementing full-scale high occupancy vehicle lanes;
2. Implementing a program of special high occupancy vehicle toll booths and full head-
of-queue privileges including consideration of establishing specially demarcated lanes
leading to high occupancy vehicle toll booths wherever found practical at appropriate
turnpike interchanges; and
3. Installing electronic identification systems to facilitate high occupancy vehicle flow
through turnpike toll booths.
(4) Implementation of Certain High Occupancy Vehicle Lanes.
(a) If the northward extension of the existing southbound high occupancy vehicle lane on
Interstate-93 north of the Charles River is found to be feasible pursuant to the feasibility
study to be completed in accordance with 310 CMR 7.37(3)(a), the MHD shall establish the
high occupancy vehicle lane and make it available for public use according to a reasonable
schedule, as defined in 310 CMR 7.37(4)(d), agreed upon between the Department and the
MHD, but in no event later than November 1, 1994. The extension shall be subject to the
following conditions:

iii westbound lanes of traffic on I-90 demand forecasts.
3. Incorporation of additional high occupancy vehicle lanes shall not be accomplished
by the addition of a new lane or lanes to Interstate-93 northbound beginning at the
Charles River Crossing and extending north towards Interstate-95.
4. Incorporation of additional high occupancy vehicle lanes shall not be accomplished
by the addition of a new lane or lanes to Interstate-90.
(c) Beginning January 1, 1994, the MHD and the MTA shall provide the Department with
an annual assessment of the potential for exceedances of the Roadway Threshold Standards.
The assessment shall be based on monitoring information collected and traffic projections
using a method which has been agreed to in advance through consultation with the
Department. The annual assessment shall, at a minimum, forecast when Roadway Threshold
Standards will be exceeded on the roadway segments identified for the MHD in 310 CMR
7.37(3)(a) and (b) and for the MTA in 310 CMR 7.37(3)(c). If the Roadway Threshold
Standards have already been exceeded as of one month prior to the date of submission of the
annual assessment, the annual assessment shall also identify the time of day and travel
conditions that were evident when Roadway Threshold Standards were exceeded.
(7) Attainment of Performance Standards.
(a) At the time that a new high occupancy vehicle lane or facility opens for public use, and
at the time that any existing high occupancy vehicle lane is expanded, the MHD with respect
to the roadway segments identified in 310 CMR 7.37(3)(a), and the MTA with respect to the
roadway segments identified in 310 CMR 7.37(3)(c), shall monitor the high occupancy
vehicle lane or facility performance, as measured by trip times, during peak periods of travel,
to ensure that high occupancy vehicle performance standards are being met. Trip times shall
be measured at least monthly and during at least five sample days each month. Measurements
shall be taken on at least one Monday, Tuesday, Wednesday, Thursday and Friday during
each month. On each of the sample days, a minimum of two time runs shall be made during
peak hours of travel in each direction for each high occupancy vehicle lane roadway segment.
(b) The MHD and the MTA shall use all appropriate and feasible measures to maintain
compliance with the high occupancy vehicle lane performance standards.
(c) Should high occupancy vehicle lane or facility performance standards for a given
roadway segment be violated for 75% of the time runs in a particular month, the agency
responsible for the operation of the lane shall file a written report describing the violations
with the Department within ten days following the end of the month in which the violation
was detected. This report shall describe the violations and shall describe a commitment by
the responsible agency to take whatever measures are feasible and necessary to return the
high occupancy vehicle lane to compliance with the performance standards, including but not
limited to changes in high occupancy vehicle eligibility or high occupancy vehicle facility
metering, and measures to increase the use of buses, car-pools and van-pools.
(d) Such reports shall be submitted to the Department for a period of two years following
the opening of each HOV lane or facility. Thereafter the MHD and the MTA shall continue
to monitor high occupancy vehicle lane and facility performance, to measure trip times as
required by 310 CMR 7.37(7)(a), and to maintain records of such monitoring and
measurements, and upon written request shall send reports to the Department containing the
information and commitments described in 310 CMR 7.37(7)(c), provided however that trip
times shall be measured at least quarterly and during at least five sample days each quarter,
and provided further that compliance with performance standards during this later period
shall be determined on a quarterly basis.
(8) Substitute High Occupancy Vehicle Projects.
(a) Based on the feasibility studies conducted pursuant to 310 CMR 7.37(3), if the MHD
or the MTA can demonstrate to the Department that a specific HOV lane listed in 310 CMR
7.37(3) is not feasible due to adverse environmental impacts or associated engineering and
financial issues, an alternative project shall be substituted in the following manner:
1. The MHD with respect to the roadway segments identified in 310 CMR 7.37(3)(a)
and (b), and the MTA with respect to the roadway segments identified in 310 CMR
7.37(3)(c), must petition the Department to accept a substitute project. All such petitions
shall be approved by EOTC prior to submission to the Department. All such petitions
shall include a demonstration that the substitute project achieves equal or greater
emission reductions of VOC, CO and NOX from mobile sources, than the installation of
an HOV lane, and that said substitute project provides for greater improvement in air
quality for VOC, CO and NOX in the area where the required high occupancy vehicle
lane is targeted, in both the short and long terms. Park and ride facilities may be proposed
as substitutes for the requirements for HOV lanes pursuant to the substitution provisions
of 310 CMR 7.37(8). Any park and ride facilities which have been built to fulfill the
requirements of, or are required to be built pursuant to 310 CMR 7.36(2), or are proposed
and accepted as substitute projects pursuant to 310 CMR 7.36, cannot also be proposed
as substitute projects pursuant to, 310 CMR 7.37(8).
2. Within 30 days of receipt of a petition and demonstration for project substitution, the
Department shall make a determination whether all information necessary for review of
said petition has been submitted, and shall notify the project proponent. The Department
shall review the petition and shall, after notice and public hearing, accept or reject said
petition in writing no later than 90 days after the Department determines that all
information necessary to review the petition and demonstration has been submitted.
3. Within 30 days after the Department accepts or rejects such a petition and
demonstration for project substitution, the Department shall file a copy of said petition
and supporting documentation and a copy of the Department action with U.S. EPA,
Region I.
(9) High Occupancy Vehicle Enforcement and Promotion.
(a) By January 31, 1993, the MHD and the MTA shall each prepare and submit to the
Department a plan describing the general program for enforcement of the high occupancy
vehicle lane system. These program submittals shall include a commitment to
implementation of the enforcement program as defined therein. Within 30 days of receiving
the enforcement program plans, the Department shall review and make recommendations
regarding the plans. Said recommendations shall be incorporated by the MHD and the MTA
into the final enforcement program plan for each agency. Specific enforcement measures
applicable to a particular high occupancy vehicle lane shall be identified in the final design
phase of the high occupancy vehicle system.
(b) By May 31, 1992, the MHD and the MTA shall prepare and submit to the Department
a plan for a general program designed to promote high occupancy vehicle use. Said plan
shall be based on a comprehensive review of techniques used to manage or promote high
occupancy vehicle use in other locations throughout the United States and Canada. The
MHD and the MTA shall, in said program, commit to implementation of selected measures
to promote the use of the high occupancy vehicle system of each agency. A specific
promotional plan for each roadway segment shall be prepared in conjunction with the final
design for each high occupancy vehicle facility.
(10) High Occupancy Vehicle Expansion to the Local Roadway Network.
(a) EOTC and MHD shall encourage the City of Boston to incorporate high occupancy
vehicle lanes and non-lane based incentives or mechanisms which promote the use of high
occupancy vehicles.
(b) EOTC shall work with the Massachusetts Port Authority to conduct studies of high
occupancy vehicle needs at Logan Airport.
(11) Reports Regarding Effects on Air Quality. Within two years from the opening for public
use of each HOV lane or substitute project on any of the roadway segments described in
310 CMR 7.37(3), the MHD, for roadway segments described in 310 CMR 7.37(3)(a) and (b),
and the MTA for roadway segments described in 310 CMR 7.37(3)(c) shall submit a report to
the Department documenting the quantitative effects of such HOV lanes or projects on levels of
VOC, CO and NOX in the areas affected. The method of determining the quantitative effects
of such HOV lanes or substitute project on air quality shall be determined in consultation with
the Department.
(12) HOV Lanes and Substitute Projects Permanent. All HOV lanes built pursuant to 310 CMR
7.37(1) through (7) and all substitute projects implemented pursuant to 310 CMR 7.37(8) shall
be permanently operated and maintained by the MHD for all HOV lanes and projects built and
implemented by it and by the MTA for all HOV lanes and projects built and implemented by it.
Either transportation agency may petition the Department to either reduce or terminate the
operation, maintenance or implementation of any HOV lane or substitute project built or
implemented by it, by petitioning the Department to build another HOV lane, extend an existing
HOV lane, or implement a substitute project by demonstrating that such lane or project will
achieve equal or greater emission reductions of VOC, CO and NOX from mobile sources and
will provide for greater improvement in air quality for VOC, CO and NOX in both the short and
long term. The Department shall act upon such petitions as provided in 310 CMR 7.37(8)(a)2.
and 3.
