GENERAL INFORMATION
The City of Port Arthur, Texas ("City") seeks to enter into a n agreement with a qualified individual, firm, or
corporation ("Respondent") to provide professional engineering services ("Services").
Respondents submitting Statements of Qualifications (SOQs) must demonstrate the resources and experience
needed to perform the Services. Additional information about the City is available at www.portarthurtx.gov.
PROJECT INFORMATION AND PURPOSE
The City seeks qualifications from firms experienced in traffic signal analysis and optimization and
installation and programming of a traffic management intelligent transportation system (ITS) using a
SCADA platform. This RFQ will result in one (1) contract with a firm or team to develop and implement a
citywide traffic signal optimization program.
Work includes collecting and analyzing traffic and travel time data, performing field observations,
developing optimized signal timing plans (including time-space diagrams and offset/split tables), selecting
and installing software compatible with traffic management intelligent transportation systems (SCADA),
implementing and fine-tuning signal timing in the field, and evaluating results through technical and benefit
analyses.
Key tasks include:
1. Data collection and analysis;
2. Field observations;
3. Coordination with TxDOT on shared signals;
4. Procurement and installation of optimization software;
5. Deploying an ITS/SCADA platform that provides real-time monitoring and control of all
Citymaintained traffic signals;
6. Integrating field equipment, controllers, communication networks, monitoring dashboards, and data
analytics systems;
7. Establishing a secure, scalable, and standardscompliant traffic management system aligned with
NEMA, NTCIP, and TxDOT practices;
8. Delivering a reliable platform capable of supporting future expansion, adaptive control, and connected
vehicle communications; and

of optimized timing plans, including time-space diagrams and offset/split parameters.
The project also includes evaluation, procurement, and installation of traffic signal optimization software
compatible with traffic management intelligent transportation systems (SCADA), followed by field
implementation, fine-tuning, and post-implementation performance assessment. Deliverables include
technical and benefit-cost analyses reports and a final program evaluation memorandum.
The primary objective is to establish a sustainable, locally managed signal timing program that improves

maximizing the performance of existing infrastructure.
Tasks:
1. Project Management Plan and Schedule
2. System Design & Integration
1. Existing Conditions Assessment and Data Collection
2. Evaluate existing traffic signal infrastructure, communications, cabinets, and controllers.
3. Perform pre-implementation data collection, field review, and system assessment.
4. Recommend SCADA/ITS infrastructure including hardware, software, and network
requirements.
5. Identify gaps in the current system and propose solutions.
6. Integrate all field signals into a centralized traffic management center (TMC).
3. Installation & Programming
1. Install and configure SCADA/ITS software.
2. Program traffic signal controllers, remote terminal units (RTUs), networking equipment, and
telemetry interfaces.
3. Provide system-level programming for monitoring, alarms, event logging, and reporting
dashboards.
