Presentation outline

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


Have you ever been stucked in traffic...?


How long is this congestion going to How long is this congestion going to last?last?

When will the traffic conditions be When will the traffic conditions be normal again?normal again?

Will the goods arrive in time?Will the goods arrive in time?

Should I choose another road?Should I choose another road?

New dynamic information services can New dynamic information services can provide answers to these questionsprovide answers to these questions


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


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.

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


Point and section data

Point dataSpeed or density based on a momentarily situation

Section dataSection speed is calculated from the time consumed to traverse the section


Anonymous travel time registration

Electronic toll collection (ETC) tags

Time-and-place (TAP) information is stored in the ETC tags


AutoPASS antennas

One antenna in each direction

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


Potential users of dynamic information

Private travelers (by car)

Freight transport and logistics

Information providers

Traffic Information Centre (TIC)


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

Details about the AutoPASS solution

Why separate antennas? Organisational aspects – we don’t 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


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

o Road networko Traffic signso Speed limitso AADT, etc.

o Traffic conditions (eg travel time)o Temporary closed roadso Weather and driving conditionso Road work, etc.


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 driver’s privacy Unaffected to user mistakes

Position log can be used for verifying estimated travel times


Communication system overview


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
