cost effective solutions

One of the most exciting parts of engineering design is creating innovative concepts during design-build pursuits which help your team win the project. On many projects traffic components such as the roadway lighting layout, specialty light pole, horizontal shift of traffic or new product can push the design-build team to a win. Another way engineers can provide cost effective solutions is by preparing detailed specifications that allow a quality product along with competition in the marketplace for several vendors.

Signing / Marking design

Often overlooked as a part of the roadway or site design, signing and marking make up a vital part of most public or private projects. Signing should convey a clear, concise message in order to direct warn, regulate and guide drivers to their destination. Pavement markings also must provide guidance and inform motorists, cyclists and pedestrians while making the most of the available roadway footprint.

Traffic Control Design

In a growth driven state like Arizona, new construction is a way of life and a driver of the local economy. Efficiently moving people and goods through a work zone is an important component to a design plan set. Whether the situation calls for a detour and weekend closure of a busy freeway or just a few flashing lights and warning signs on a rural highway, each project should be evaluated and designed thoroughly.

Traffic Impact Analysis

The TIA is a vehicle allowing a municipality to evaluate the potential traffic impacts from a new development. A quality TIA can fairly analyze what effect new traffic from the development will have on the adjacent street and transit network. Savvy traffic engineers can explain the details of the study concisely, while recommending appropriate solutions which benefit the traveling public and fitting within the concept of the developer and/or architect.  

Inter-Agency Coordination

More now than ever, many municipal and private projects fall under the jurisdiction of multiple agencies. For example, the Arizona Department of Transportation (ADOT) is responsible for a rural route or highway traveling through a local city or town, which presents potential conflicts.

Furthermore, in roadway lighting and traffic signal design, coordination with the power or utility company whose transmission lines parallel the adjacent roadway is vital. Knowing the intricate details of each agency's requirements and working diligently to follow them and communicate this information to project stakeholders is often the key to a successful project.   

ITS Design

ITS systems have allowed drivers and transportation professional to collect and disseminate significant amounts of information is a short timeframe. In fact, it is hard to remember a time when the overhead freeway sign didn't warn you about a crash or closure a few miles ahead of you. Designing fiber optic cable, underground conduit and pull boxes and connections between traffic signals and a fiber backbone are all a part of this innovative technology which has become part of our everyday lives.  

Traffic Signal Design

Balancing the art of designing for vehicular, pedestrian and bicyclists while minimizing underground conflicts is a skill which takes time to master. In addition, a knowledgeable designer must keep up with the latest industry advancements with regard to video detection, emergency vehicle pre-emption and traffic signal controller products.
