Highway and Traffic Engineering

The core purpose of Highway and Traffic Engineering is to maintain safe and efficient operation of surface transportation facilities through designs that meet present and future traffic volumes and uses.  By study of the interconnecting networks of roads and their relation to other modes of transportation in conjunction with actual traffic data, AEA provides planning and design services that ensure movement of people and goods in accordance with these principles.

AEA’s highway and traffic engineering design services include:

    • Roadway Design and Geometrics
    • Signalized Intersections
    • Signing and Striping
    • Traffic Counts and Analysis
    • Guide Rail
    • Traffic Control and Staging/Maintenance of Traffic
    • Concept Development, Preliminary Engineering, and Final Design

Intelligent Transportation Systems (ITS) Engineering

Intelligent Transportation Systems (ITS) come in many shapes and sizes, but share one common goal – to improve safety and efficiency of surface transportation facilities through application of information and communications technology.  Often these systems require thinking beyond the traditional borders of civil, traffic, and electrical engineering.

AEA has a proven track record of delivering successful ITS designs by utilizing innovative equipment and methods to meet the specific needs of each project.  We are leaders in using the latest devices, including cameras, color- and video-capable signage, wireless communications technologies, and regional standards such as TRANSCOM’s Travel Time System.

In performing ITS designs, we use a methodical systems engineering-based approach to define clear project objectives, and partner with all stakeholders early in the process to ensure successful system delivery.  It’s no wonder that we have served as the State of New Jersey’s on-call ITS design consultant since our company was founded, and that many of our clients keep coming back to us to perform the ITS designs of their complex highway projects.

Our broad range of experience covers all of the following aspects of specifying and installing ITS systems, from conception through integration and operation:

    • ITS Devices (Cameras, Dynamic Message Signs, Weather Stations, Roadside Units, Travel Time Systems, Variable Speed Limit Signs)
    • Connected Vehicle Design
    • Adaptive Traffic Control Systems
    • Communications Design (Fiber Optic Cabling, Wireless Radio, Network Topology and Switching)
    • ITS Architecture Development
    • Systems Engineering

Roadway Lighting and Electrical Engineering

Electrical and lighting systems are integral to the safety and success of transportation facilities as varied as highways, traffic signals, and airport runways.  Roadways function more efficiently with properly designed lighting systems; movable bridges will not operate without the machinery that lift them; and pilots rely on airport guidance systems to land airplanes with little room for error.

And while these systems typically represent only a small portion of the initial construction cost for a project, they represent a large cost of the ongoing maintenance for facility operators.  This attention to lifecycle cost is just one aspect of the total engineering approach that sets AEA apart from other Electrical and Lighting designers.

For example, we have a proven record of optimizing lighting designs by balancing the competing elements of light levels, aesthetics, power consumption, and construction cost, while maintaining context-sensitive designs that do not create unnecessary light pollution or environmental impacts.

The following list indicates our broad range of experience in electrical, power, and lighting designs:

    • Highway and Sign Lighting
    • Power distribution systems
    • Tunnel Control systems
    • Airport lighting
    • Navigation and aviation aids
    • Electronic Toll Collection (E-Z Pass) Systems
    • Automated parking systems
    • Relay and PLC-based logic control systems
    • Supervisory Control and Data Assessment (SCADA) Systems

Utility Engineering

AEA has extensive experience in utility investigations/relocations and has been fully involved in multiple projects that required comprehensive solutions to accommodate existing utilities and proposed construction. We are well versed in the utility process of various clients such as the NJDOT and NJTA and ensure that required standards/formats are adhered to. Our services extend from initial verification to the execution of final agreements/construction. Steady communication with utility owners and the client is maintained so there are no delays in the project and the most accurate information is always available and utilized. All projects include field verification, discussions with utility owners, relocation or temporary support design, preparation of contract documents/utility agreements, and construction support. Additional tasks such as subsurface investigations and advanced staging are also included based on the needs and goals of each particular project so that the most efficient design is achieved.

AEA’s utility services include the following:

    • Utility coordination with client and utility owner
    • Field investigations and verification
    • Coordination of Subsurface Investigations
    • Alternatives Analysis
    • Utility layout and design
    • Development of utility relocation plans, agreements, and checklists
    • Construction support
