API v. 2.0

   Overview

This API description covers Ruter’s ADT agreement v2.0. The API describes a set of MQTT topics which are used to distribute data onboard public transport vehicles/vessels as well as between the vehicle/vessel and Ruter’s Back Office or vv.

1.1        Upgrades to the API

The API follows the upgrade cycles of ADT. Major releases are done more or less once a year and usually include breaking changes.

Minor/build releases are performed as continual deliveries and are non-breaking. New versions of this document will be published when new topics and/or fields are added.

1.2        Consumer Client Requirements

Clients consuming information posted on the topics must be tolerant to:

  • That optional properties can be null or left out.

  • That arrays can contain any number of elements including zero.

  • That returned data can be extended with new properties without notice.

1.3        Quality of Service, Retained Flag and Persistence

Generally, QoS level 1 is applied for most topics and the retain flag is true for most topics. See the respective topic for precise info.

Subscribers should start with Clean Session set to True to assure that they get the latest information at reconnection (the retained info) and avoid first having to process a long queue of outdated old information that in reality hinders new relevant information to reach the subscriber.

1.4        List of topics

The listed topics are topics that are to be produced in either the vehicle or in the Ruter Back Office.

All data must be JSON and UTF-8 encoded.

Topics are categorized by a thematic perspective, according to the topic structure proposed for ITxPT at the time of writing.

1.5        Translation of topic names

Global topic names are generally written on the format of <recipient>/<sender>/<vehicleid>/<topic> to make it easy to identify the source and destination of the messages.

Local topic names have omitted the <recipient>/<sender>/<vehicleid> part in order to have onboard equipment pre-configured with vehicle independent settings.

All topic names must thus be rewritten local/global in the MQTT bridge according to a provided configuration file.

2.7        Telemetry

Topic

ruter/<PTO>/<vehicleID>/sensors/telemetry

Retain

No

QoS

0

 

Several different kinds of sensor/telemetry data are available varying by vehicle type For traditional busses, FMS is the standard that defines what data about the vehicle is published on the FMS bus and further on by ITxPT FMStoIP service.In addition, vessels, trams and different bus types have proprietary data not captured by FMS.

According to the data centric approach from ITxPT, several of these data types (door, location, stop button etc) have been assigned separate topics as being described in this document. However, data types required by Ruter that haven’t yet been described in the MQTT structure from ITxPT, will still be handled by the general Telemetry topic that was introduced by Ruter in 2019.

All such data are defined by unique, 32 bit, identifiers. Data caught from the FMS bus retain their PGN numbers as the last 16 bits of the ID. Data not coming from the FMS bus follow a separate addressing scheme, with addresses allocated by Ruter on request. Please note that PTOs are free to decide if they want to use FMS or a non-FMS data source to provide the data.

To utilize FMS data in Ruter’s architecture, Operators can either set up an FMS2IP service or use any other means to subscribe to the FMS bus data. Note that there must be one separate MQTT message per FMS PGN.

The identifiers are constructed this way:

Bytes

Description

1

Source identifier (0x00 FMS, 0x01 Non-FMS)

2-4

Source-specific id, e.g. FMS PGNs

All FMS PGNs become "0000" + 4-digit hex PGN, i.e. “0000FE4E” for PGN FE4E.

 

Available Non-FMS standard data identifiers

Optional unless stated explicitly in the main ADT document.

Telemetric data in the vehicle are often refreshed at a very high rate and are originally intended to be consumed directly in the vehicle. Ruter’s enterprise architecture requires the same data to be consumed by Ruter’s back office. This requirement, along with constrains related to mobile networks, doesn’t allow us to use the same refresh rates as are ideal onboard vehicles.

3.2        Current Block

Topic

<PTO>/ruter/<vehicleID>/oi/current_block/state

Retain

Yes

QoS

1

Normally this topic indicates which block this vehicle is currently signed on to according to the backoffice or that it only assigned but not yet signed on or that it is not even assigned. This is usually a result of what was proposed by the driver on-board (see ruter/<PTO>/<vehicleID>/di/assignment_attempt/block) and then confirmed as valid by the back-office. It could also be based on an overriding decision enforced by the operation control centre.

Note that if a ruter/<PTO>/<vehicleID>/di/assignment_attempt/block is not answered by the back-office within a configured duration it is assumed that contact is lost with the control centre and then the proposed block will be accepted and exposed on this topic.

Fields

Name

Type

Description

fromDateTime

string

Time from which the sign on or assignment applies. ISO 8601, UTC

state

string

Possible values: “SIGNED_ON”, “ASSIGNED”, “NOT_ASSIGNED”,

blockRef
