Street Traffic Studies Ltd. provides traffic engineering services in conjunction with development planning or specific engineering projects.
In areas with high volumes of vehicular and pedestrian traffic, and on larger sites with internal circulation systems, a properly engineered design will ensure safe, efficient movement. Street Traffic Studies Ltd. can prepare construction design drawings for roadway widening and channelization projects, and can recommend ways to describe proposed system changes to public officials.
Traffic Signals
Integrating a site's traffic facilities with the surrounding public highway system may require the design of new traffic signals. Such plans and specifications must be reviewed by public agencies.
Street Traffic Studies Ltd. can determine if an intersection under consideration for signalization will meet standard warrants, and then can review these warrants with the appropriate public agency. Once a location meets warrants, we can prepare the base map, design the signal, review designs with the public agency, prepare the cost estimate for construction, and prepare the construction plans.
If the local municipality requires the developer to install the traffic signal, Street Traffic Studies Ltd. can prepare the construction plans, advertise the project, receive bids, and assist in supervising the installation. Street Traffic Studies, Ltd., can undertake all of the above tasks or any combination - from start to finish.
Street Traffic Studies Ltd.'s design staff has been responsible for the design of over 200 traffic signal installations in the states of Maryland and Virginia since 1985. While the basic parameters remain the same, each project tends to have its own special requirements. With the extensive experience of our design staff, we are able to recognize potential problems in advance and develop solutions from the onset. The large number of signal projects translates directly into a high involvement with the state and county reviewing agencies. Based on the Maryland State Highway Administration's consultant rating program, Street Traffic Studies Ltd. has been the highest rated signal design team since 1987. To our clients, both public and private, this rating translates into reduced project costs and equally important, significantly reduced review/approval periods.
In order to further improve the service our design team provides to our clients, Street Traffic Studies Ltd. uses the Intergraph Microstation and AutoCAD computer aided design programs and has invested in specific custom upgrades and training to allow the integrated programs to be of optimum benefit. Our policy is to provide each designer with their own CAD workstation.
Because of their broad experience, our designers have been able to cut the normal design and review times to a minimum. Many times, the need for a signal modification is not identified at the onset of a project. Thus, our ability to quickly and accurately respond to the problems at hand, while avoiding future redesigns, has allowed many projects we have been involved with to proceed with little to no delay.
Recognizing that the design or modification of traffic signals is typically a portion of a highway construction or development project, Street Traffic Studies Ltd. frequently serves as subcontractor to major design firms. Our specialization in signalization, highway lighting, and traffic control has allowed us to keep abreast of all current standards and requirements to expedite our clients' projects.
Traffic Operations
While our services relative to traffic operations tend to orient to our public contracts with State Departments of Transportation and County Departments of Public Works, these Street Traffic Studies, Ltd. services directly meet the needs of many development planning studies.
As traffic volumes increase regionally, approval of development projects may require offsite improvements. The realistic evaluation of the alternatives available in conjunction with the guidelines of the reviewing agencies to expedite the development of improvements
consistent with the development project and capable of achieving agency approval.
Street Traffic Studies Ltd. has performed a wide range of traffic engineering studies including such tasks as signal warrants analyses, speed & delay evaluations, travel time studies, and cross slope evaluations on curves using ball bank indicators. In addition, Street Traffic Studies Ltd. has prepared signing and pavement marking plans, evaluated high accident locations, and prepared work zone traffic control plans. Our engineers and technicians possess a thorough knowledge and understanding of the Manual on Uniform Traffic Control Devices and the various engineering directives and guidelines with respect to traffic engineering.
In order to expedite the analysis of site specific problems, there exists a broad array of computer software available. Street Traffic Studies Ltd.'s computer software library includes, and our engineering and technical staff are fully trained in the use of, the Highway Capacity Manual Software, SYNCHRO, Transyt 7F, Passer III, SOAP, the Arterial Analysis Package, Lotus 123, Word Perfect, Intergraph Microstation and AutoCAD. Each of Street Traffic Studies Ltd.'s engineers have direct access to high speed personal computers within their offices.
