Traffic Flow Analysis: Adelaide Coordinated Traffic Signal (ACTS) Data

This report presents an analysis of the Adelaide Coordinated Traffic Signal (ACTS) system, aiming to understand traffic flow management and system performance. The study examines the challenges of urban traffic congestion and the need for innovative control strategies, including traffic signal coordination. The report reviews the literature on traffic light control, phases, stages, and traffic controller systems. The research methodology involves statistical data analysis to evaluate the ACTS system, with the goal of making data-driven recommendations. The report also includes a timeline for the project, references to relevant literature, and a discussion of the research aims, which include understanding the ACTS system, evaluating its performance through data analysis, and providing recommendations for traffic management. The analysis utilizes various statistical techniques to assess the ACTS system's effectiveness and compares the findings with information gathered from literature. The report also references the SCATS system and its applications, including data for modeling and environmental audits, emphasizing the importance of understanding data limitations and supplementing it with other sources like manual turning counts. The data analysis includes mean weekday and weekend volumes, excluding holidays and special events, and the report aims to contribute to the optimization of traffic systems based on the identified variables.

DATA ANALYSIS

INTRODUCTION
 The challenges and hurdles linked
with the increase in the urban
traffic jam demand for the
strategies of innovative control that
enable vehicles to move more freely
for example coordination of the
traffic signals.

 Mostly the strategies are pegged on
a central traffic-responsive control
system in which the challenge in
implementation and maintenance
increases when the number of
traffic elements increases such as:
detectors
traffic lights; and
specialized hardware

 Lack of interoperability is yet another
challenge among such elements especially
when bought from various producers
 Thus, spatial and functional decentralization
is needed. Achievement of spatial
decentralization has remain a main objective
of traffic engineering
 The role of reduced communication and
perception has been extensively covered by
authors in literature

 The need for implicit learning and
communication techniques has also been
covered
 This remains the main issue in traffic domain
 Decentralized systems in traffic may be of
numerous roles:
 Training synchronization of numerous
neighbouring intersections on an arterial,
microscopic simulation and agent based
macroscopic traffic agents
 Controlling traffic

 In some instances, a process that is
instance based and a centrally
regulated coordination is used in
attaining cooperation
 This coordination type is
nevertheless unsatisfactory for
traffic signal control domain as a
result of:
 Real time constraints
 Interoperability constraints

 Real time constraints: Agents are
not able to afford negotiation
mechanisms that are sophisticated
and time consuming as a result of
the need to react instantly to
prevailing traffic situation
 Communication may also be noisy
 Interoperability constraints result
from the hardware producers

 The currently available
hardware does not offer
standard
communication
protocols even through
there are efforts to
have standard
communication
protocol.
Arterial used in simulation

RESEARCH AIMS
 The main aim of this study is to analyze the data of
the Adelaide Coordinated Traffic Signal(ACTS)
system to gain an understanding of the
management of traffic flow systems and their
performance
 The other aims include:
Understand Adelaide Coordinated Traffic Signal(ACTS)
system
Establish the performance of Adelaide Coordinated
Traffic Signal(ACTS) system through analysis of data
Make recommendations based on th data analyzed on
traffic management
Evaluate the various methods of traffic data
management

LITERATURE REVIEW
Coordination and control of traffic light
 The usual function of traffic lights
needs beyond slight control and
coordination to ascertain traffic
moves as safely and as smoothly as
possible and that pedestrians are
safeguarded when they cross the road
at various points
 Various control systems are utilized in
achieving this

PHASES AND STAGES
 The concept of phases is used by traffic
controllers
 Phases define direction of moved of a
collection together
 For example, a simple T-junction may be
composed of three phases of vehicle
movement, one for every arm of junction
