 CVO Interoperability



ITS/CVO Interoperability Guiding Principles

The following principles pertain to interoperability issues facing the deployment of ITS in the trucking and motorcoach industry.  They have been copied from the ITS America website and are presented in their entirety.

ITS/CVO Interoperability Guiding Principles

These interoperability guiding principles were prepared in recognition of the importance of promoting interoperability in the implementation of Intelligent Transportation Systems (ITS) for Commercial Vehicle Operations (CVO). They have been adopted by the ITS America CVO Technical Committee.

These principles represent values and are designed to be flexible and durable to accommodate a broad scope of technological, social, and cultural change. ITS America may, however, need to revisit them periodically to assure their applicability and effectiveness.

These principles are advisory, intended to educate and guide transportation professionals, policy-makers, and the public as they develop interoperability guidelines for specific ITS/CVO projects. They are not intended to supersede existing statutes or regulations. Initiators of ITS/CVO projects are urged to publish the interoperability principles that they intend to follow. Parties to ITS/CVO projects are urged to include enforceable provisions for assuring interoperability in their contracts and agreements.


IGP #1

The CVO community will work to implement interoperable ITS/CVO systems in all United States jurisdictions.

IGP #2

The CVO community will work with the CVO communities in Canada and Mexico to implement interoperable ITS/CVO systems throughout North America.

IGP #3

The CVO community will work to ensure that ITS/CVO systems, where appropriate, are interoperable with other ITS systems (e.g., electronic toll systems).

IGP #4

Interoperable ITS/CVO systems will be achieved through the development, adoption, and adherence to common standards for hardware, systems/software, operations, and program administration.

IGP #5

Each jurisdiction will support the national ITS/CVO information system architecture and data exchange standards developed under the Commercial Vehicle Information Systems and Networks (CVISN) program.

IGP #6

Transponders shall have a unique identifier.

IGP #7

Information systems supporting electronic screening, credentials administration, and safety assurance will use:

7a. US DOT numbers for the identification of both interstate and intrastate motor carriers.

7b. Commercial Drivers License (CDL) numbers for the identification of commercial drivers.

7c. Vehicle Identification Numbers (VIN) and license plate numbers for the identification of power units.


IGP #8

Commercial vehicle operators will be able to use one transponder for power unit-to-roadside communications in support of multiple applications including electronic screening, safety assurance, fleet and asset management, tolls, parking, and other transaction processes.

IGP #9

Public and public-private DSRC applications will support open standards that are consistent with the national ITS architecture.


IGP #10

Public and public-private organizations will support open data exchange standards for the state-state, state-federal, state-provincial, and carrier-agency exchange of safety and credentials information as described in the national ITS architecture.


IGP #11

Jurisdictions will support common standards for placement of DSRC transponders on trucks and buses to ensure the safe and cost-effective use of transponders.

IGP #12

Jurisdictions will support a common set of recommended practices concerning the selection, layout, and signage of roadside screening sites (i.e., weigh stations, ports-of-entry, international border crossings, and temporary inspection sites) to ensure safe operations.

IGP #13

Jurisdictions will support a common performance standard for roadside electronic enforcement screening and passage of transponder-equipped motor carriers to ensure equity in enforcement.

IGP #14

Roadside electronic enforcement screening criteria will include the following: motor carriers must be enrolled in the jurisdiction's program; must meet the jurisdiction's enrollment criteria; and must meet all legal requirements established by the jurisdiction.

IGP #15

Jurisdictions will support quarterly reviews of carrier qualifications to ensure that the standards evolve to meet the changing needs of government and motor carriers.

IGP #16

A jurisdiction will not retain the identification codes or other data from the DSRC transponders of passing motor carriers who are not enrolled in the jurisdiction's program.

IGP #17

Jurisdictions will support a common performance standard for selection of vehicles and drivers for roadside safety inspection.

IGP #18

Jurisdictions will support a common performance standard for recording and reporting roadside safety inspection results.

IGP #19

Jurisdictions will support a common performance standard for reconciling disputed roadside safety inspection results.


IGP #20

Motor carrier participation in ITS/CVO roadside electronic screening programs will be voluntary; motor carriers will not be required to purchase or operate DSRC transponders.

IGP #21

Motor carriers will have the option of enrolling in any ITS/CVO roadside electronic screening program.

IGP #22

Jurisdictions will support uniform criteria for enrollment of motor carriers in ITS/CVO roadside screening programs.

IGP #23

Enrollment criteria will include consideration of safety performance and credentials status (e.g., registration, fuel and highway use taxes, and insurance).

IGP #24

No jurisdiction will be required to enroll motor carriers that do not meet the criteria for enrollment.

IGP #25

Motor carriers may obtain a DSRC transponder from the enrolling jurisdiction or a compatible DSRC transponder from an independent equipment vendor of the motor carrier's choice.

IGP #26

Each jurisdiction will determine the price and payment procedures, if any, for motor carriers to enroll and participate in its ITS/CVO electronic screening program.

IGP #27

Jurisdictions shall work to establish business interoperability agreements among roadside electronic screening programs.

IGP #28

A jurisdiction will make a motor carrier's DSRC transponder unique identifier available to another jurisdiction upon written request and authorization by the motor carrier.

IGP #29

Jurisdictions will work toward development of a single point of contact for motor carriers enrolling in more than one ITS/CVO roadside screening program.

IGP #30

Each jurisdiction will fully disclose and publish its practices and policies governing, at a minimum:

30a. Enrollment criteria;

30b. Transponder unique identifier standards;

30c. Price and payment procedures for transponders and services;

30d. Screening standards;

30e. Use of screening event data; and

30f. Business interoperability agreements with other programs.

Date approved by the Board of Directors: April 22, 1999

Note: These guiding principles address only issues of interoperability. They do not address all issues related to concepts of operations or privacy and data control. These issues are addressed in separate guiding principles.
