AIS 140 complied GPS Tracking Device

AIS 140 complied GPS Tracking Device

INTRODUCTION
The Government of India felt the need for a permanent agency to expedite the
publication of standards and development of test facilities in parallel when the work
on the preparation of the standards is going on, as the development of improved
safety critical parts can be undertaken only after the publication of the standard and
commissioning of test facilities. To this end, the erstwhile Ministry of Surface
Transport (MoST) has constituted a permanent Automotive Industry Standards
Committee (AISC) vide order No. RT-11028/11/97-MVL dated September 15, 1997.
The standards prepared by AISC will be approved by the permanent CMVR
Technical Standing Committee (CTSC). After approval, the Automotive Research
Association of India (ARAI), Pune, being the secretariat of the AIS Committee, will
publish this standard.
Intelligent Transport Systems (ITS) are globally proven systems to optimize the
utilization of existing transport infrastructure and improve transportation systems in
terms of efficiency, quality, comfort and safety. Having realized the potential of ITS,
Government bodies and other organizations in India are presently working towards
implementing various components of ITS across the country.
The first step taken for creation and implementation of ITS was holding a National
Workshop titled “User Requirements for Interactive ITS Architecture”, which was
conducted as a collaboration between SIAM and ASRTU on 26th & 27th February
2015. This was primarily focused on ITS in Public Bus Transportation. Nonetheless,
the workshop helped to create the outline for “National Intelligent Transport System
Architecture and Policy for Public Transport (Bus)”, which was submitted by ASRTU
and SIAM to the government
In the 44th & 45th CMVR-TSC, Chairman had directed – standardization activities to
be initiated on Intelligent Transportation Systems (ITS) – Vehicle Location Tracking,
Camera Surveillance System and Emergency Request Button. The committee
intended to extend the above user requirements to all public transportation namely –
buses, taxis, etc. The current document covers the requirements for Vehicle Location
Tracking and Emergency Button. The other ITS components like PIS, CCTV system,
Fare collection etc. are deliberated and would be addressed in later phase and could
be added as separate parts to the current document..
Based on these directions, the AISC Panel on ITS has prepared this AIS-140 titled,
“Intelligent Transportation Systems (ITS) – Requirements for Public Transport
Vehicle Operation”
The panel has also deliberated and identified the necessary elements for an effective
implementation of vehicle level ITS system.
This standard has been prepared by considering inputs received from all stake holders
on ITS, mainly –

a. Directions of CMVR-TSC
b. Detailed Specification Document on Vehicle Tracking Devices (dated 4th March
2015, published by MoRTH)
c. Report of Department of Telecom (Telecom Engineering Centre) Automotive
Working Group on M2M enablement in Intelligent Transport System (ITS)
This AIS on ITS, has been provisioned for device level approval; including
construction and target vehicle level approval. Device level approval is needed to
enable retro-fitment of ITS systems on in-use vehicles. This will ensure ITS Backend
Control Centre infrastructure already presents with the STUs can be more fully
utilized and make the investment in the Backend Control Centre infrastructure more
viable.
As per the direction of CMVR-TSC which needed the Communication Protocol and
Backend Control Centre requirement for tracking and handling the alerts to be
detailed, the same has been addressed in Section 6 & 7, as detailed below.
 The devices would transmit data to the Backend Control Centre using 2G/3G/4G
wireless connectivity (with SMS fall back) as per the protocol provided in
respective sections (Section 6).
 The data from the devices would travel over the wireless telecom service provider
network and finally get delivered at the Backend Control Centre. The detail about
Device to Backend Communication Mechanism is mentioned in Section 7.
BIS and AIS both have panels which are formulating standards on ITS. It is our belief
that taking the AIS route for the 1st implementation would give the faster time for
adoption. Experts in the BIS panel and in DIMTS who are working on these subjects
have been co-opted and invited to work in the AIS panel to make the AIS as robust as
possible. Once implemented and all implementation problems in this emerging
technology have been eliminated, BIS standard can be made with further inclusions if
any resulting from consultations with the wider stakeholder community. Because of
these reasons, we recommend the AIS route for regulation creation and first
implementation.
One of the major concerns which has been raised during the panel meetings is on the
issue of privacy encroachments by ITS systems. Some overseas member countries of
the 1958 agreement have been continuously emphasizing in WP29 forums that the
regulated ITS system must not encroach on privacy. Towards this, the panel has
submitted a document titled ‘Data Privacy in Transportation ITS’ To help the system
developers deal with these issues. Further, system developer can also take guidance
from ‘IS/ISO/TR 12859: 2009 – Intelligent Transport Systems — System Architecture
— Privacy Aspects in ITS Standards and Systems’ while developing their systems to
meet the requirements of this standard. The Panel and the Automotive Industry
Standards Committee (AISC) responsible for preparation of this standard are given in
Annexure-D and Annexure -E respectively.
