Presentation outline

• Overview of the DynamIT project
• The test site
• Travel time registration by using ETC tags
• Information services

3
Have you ever been stucked in traffic...?
4
How long is this congestion going to last? When
will the traffic conditions be normal
again? Will the goods arrive in time? Should I
choose another road?
New dynamic information services can provide
answers to these questions
5
Background

• Infrastructure is a limited resource
• Efficient utilisation of the road infrastructure
  is important
• Accurate and updated information about traffic
  conditions is required
• Freight transport must provide high quality
  customer
• service
• Efficient logistics is fundamental
• Precise information about status of delivery
• Information about positions of the vehicles and
  traffic conditions is required

6
Objectives

• The project aims at developing a system for
  establishing dynamic traffic information
• This is obtained by
• Collecting and refining raw data
• Evaluating the advantages and willingness to pay
  for dynamic information services
• Developing requested services
• Developing and proposing models for data
  ownership and responsibility

Generating dynamic information

• Data collected at the test site is combined with
  data from other sources and refined into useful
  dynamic traffic information
• General traffic flow
• Delay and travel time
• Short time prediction of delay and travel time
• Incidents, weather and road conditions
• Freight transport
• Positioning and tracking of specific vehicles
• Customer information (ETA)
• Fleet management, etc.

11
Test Site E18 Oslo - Larvik

• Total length 120 km
• 4 and 6 lanes freeway 75 km
• 2 lanes highway 45 km
• Main road high traffic volume
• High part of commercial transport
• Re-routing possibilities
• 14 antennas (7 in each direction)
• Placed at bottlenecks and important information
  points
• 17 points with inductive loops

12
Point and section data
Point data Speed or density based on a
momentarily situation Section data Section speed
is calculated from the time consumed to traverse
the section
13
Anonymous travel time registration

• Electronic toll collection (ETC) tags
• Time-and-place (TAP) information is stored in the
  ETC tags

14
AutoPASS antennas

• One antenna in each direction

15
Travel time registration
Dynamic Database
TAP Information
As the vehicle passes a TTMP -Time-And-Place
(TAP) information are written from the antenna to
the OBU -The TAP information are read at the next
TTMP
16
Potential users of dynamic information

• Private travelers (by car)
• Freight transport and logistics
• Information providers
• Traffic Information Centre (TIC)

17
Information channels

• Open Internet service and WAP service
• Traffic information (travel time and delay)
• Restricted Internet service
• Traffic information and fleet management for one
  major freight transport company
• Variable message signs (VMS)
• Dynamic message signs (DMS)
• Short message services (SMS)
• Radio

Details about the AutoPASS solution

• Why separate antennas?
• Organisational aspects we dont have to involve
  the finance companies
• Full control of the equipment
• Amount of ETC tags
• 90 of the vehicles nearby Oslo have ETC tags
• 50-60 of the vehicles nearby Larvik have ETC
  tags
• Anonymous system
• No personal information is identified or stored

24
Dynamic data for road traffic

• Static data
• Data which are valid for a long time period
• Dynamic data
• Data which describes the actual real time
  condition
• Valid for a limited time period minutes, hours,
  days, seasons

• Road network
• Traffic signs
• Speed limits
• AADT, etc.
• Traffic conditions (eg travel time)
• Temporary closed roads
• Weather and driving conditions
• Road work, etc.

25
Positioning (1)

• GPS and GSM techniques are tested
• GPS position is registered every 30 second
• GSM position is polled every 60 second
• 8 heavy goods vehicles have participated
• Driver independent log unit
• Protects the drivers privacy
• Unaffected to user mistakes
• Position log can be used for verifying estimated
  travel times

26
Communication system overview
27
Efficient logistics

• Excellent customer service requires
• Information about the vehicles position
• Knowledge about the traffic conditions on the
  different routes the driver may choose getting to
  his/her destination
• Estimated time of arrival
