6. Free Way Management
System
Freeway-management systems consist of
strategies/system components and technologies
combined to monitor, control, and manage
freeway traffic more effectively.
7. Importance of Freeway
Management system
Flow of traffic
Information to motorists about crashes and
construction
Help agencies for better response to incidents
9. Ramp Meters
These signals at
freeway entrances
regulate the timing of
vehicles merging on to
freeways. Ramp meters
operate during the
morning and afternoon
commute times.
10. Cameras
Video images from cameras provide a real-time
view of traffic on freeways.
Agencies monitors these cameras from the Traffic
Operations Center to see how traffic is moving on
freeways and identify trouble spots.
11. Dynamic Message Signs
These electronic
overhead signs can
display timely and
important traffic
information such as
incidents, upcoming
construction and
closures, restrictions on
freeway
13. I.T.S
Intelligent Transport Systems (ITS) is at the heart
of what keeps us safe in our city’s roads and
tunnel systems.
It includes;
Cameras, display screens, traffic signals, j-eyes, e
traffic scan, sensors etc.
15. 2) J-EYES:
Junction electronic eyes.
A system of surveillance
cameras that monitor the
traffic condition at major
signalised junctions.
The signal can modify its
timing according to the
density of traffic.
Can detect traffic offenses.
16. 3) GREEN MAN+:
Extends green man
time for both the
elderly and
pedestrians with
disabilities to
cross the road.
17. 4) LCD screens:
Displays the real
time speed of
vehicles.
Displays info.
18. 5) PARKING GUIDENCE SYSTEM:
Provides real-time
information on
parking spaces.
19. “INCIDENT MANAGEMENT
SYSTEM”
1) BACKGROUND:
Highway incidents disrupt the normal operation of the
transportation system.
Incidents can occur due to;
a. Vehicle disablement
b. Crash
c. Hazardous material spill
d. Bridge collapse
20. INCIDENT CONTROL SYSTEM:
IT is a systematic tool used for the command, control, and coordination
of an emergency response
It works by the co-ordination of various agencies.
various stake holders and their duties:
1. Law enforcement;
• Secures incident scene
• Assists responders in accessing
the incident scene
22. 2) Emergency medical services:
• Provides medical treatment to those injured at the incident scene
3) Emergency management agency:
• Coordinates government response and resources
• Provides technical expertise
• Provides evacuation recommendations
4) Transportation agencies:
• Protects incident scene
• Monitors traffic operations

24. Electronic Toll Collection (ETC) System
The Electronic Toll
Collection (ETC)
System is a new toll
system designed to
enhance
convenience for
drivers by enabling
cashless toll
collection and thus
Reducing congestion
at High-way
tollgates.
25. Objectives of ETCS
Avoid the fuel loss.
Saving of time in collecting toll.
Avoid financial loss.
Reduce longer waiting time in a toll queue.
Provide traveler ease of toll payment.
Reduce illegal toll gate entry.
26. RFID
(Radio Frequency Identification)
RFID is a technology to identify and
authenticate tags that are attached on
vehicles.
Each user holds a unique id for his vehicle,
when user scans his ID, some amount is charged
from his account depending upon his vehicle
category.
29. Emergency allow vehicles to control
traffic lights
System that allows the normal operation of traffic
lights to be preempted. The most common use of
these systems is to handle traffic signals in the
path of an emergency vehicle and allowing the
emergency vehicle right-of-way, to help
reduce response times and enhance traffic safety.
30. Implementation
They can be installed on road vehicles
Integrated with train transportation network
management systems
Operated by remote control from a fixed location,
such as a fire station or by an emergency call
center.
NOTE:
Traffic lights must be equipped to receive an
activation signal to be controlled by any system
intended for use in that area. A traffic signal not
equipped to receive a traffic preemption signal will
not recognize an activation, and will continue to
operate in its normal cycle.
31. Vehicular device types used
Acoustic
Systems of this type override the traffic signal
when a specific pattern of tweets from the
siren of an emergency vehicle is detected.
Line-of-sight
A vehicle that uses a line-of-sight traffic signal
preemption system is equipped with an emitter
which typically sends a narrowly directed signal
forward, towards traffic lights in front of the
vehicle, to attempt to obtain right-of-way through
controllable intersections before arriving at the
intersection.
32. Vehicular device types
Global Positioning System
These systems require software and a
communications platform to determine where
the activating vehicle is located, in which
direction it is headed, which traffic lights
should be preempted
The ability for the central application to
activate the desired traffic lights promptly.
