Traffic Impact Analysis is an integral portion of developing transportation master plans and corridor studies related to the planning of traffic and transportation issues including:
- Design of roadways, interchanges, and intersections
- Transportation system surveillance and modeling
- Emergency evacuation / incident management
Corridor improvements to support:
- Economic development
- Improve traffic operation efficiency and safety
- Interstate widening
- Commercial, industrial, and retail developments
- Residential developments
- Transportation planning for major events
Includes projects involving the planning and design of intersections and their associated signalization requirements:
- Specific intersection development and design to improve capacity, safety, and efficiency
- Individual signalized intersections
- Computerized signal systems for major arterial corridors
- Traffic operations assessments and enhancements of major arterial corridors, local and state, to alleviate traffic congestion
- Local major arterial corridor/roadway design, which includes new or modified intersections
- Commercial/Retail/Industrial developments requiring new intersections with adjacent arterials for site ingress and egress
- Residential single family and multi-family developments requiring new intersections with adjacent arterials for site ingress and egress
- Interchanges for exits and entrances to major highways and interstate corridors highways and roadway corridor extensions and widening projects
Several of the projects include protection control circuitry – emergency vehicles and railroads. As part of our scope of services for signal system design, the timing and phasing task was inclusive of intersection and corridor optimization utilizing various traffic engineering software such as TEAPAC-Signal 2000, PASSER II, CORSIM, and VISSIM II. Many of our traffic operational analysis and impact analysis projects include capacity analysis (existing and future) for both signalized and unsignalized intersections. Signal warrant analysis are also performed for those intersections proposed for signalization.
An area in which Urban Systems has an extensive amount of experience is Traffic Control Device Plans and Detour Plans. They assure that the public is not seriously inconvenienced by construction activities. USI has often met with local business owners to incorporate their needs into the Traffic Control Plans.
USI has completed numerous federally funded Urban Systems projects. These projects included rural and urban roadway design as a major component of the project scope. The roadway design included surveyor coordinator, utility relocation, identification of right-of-way limits, and acquisitions, as well as all civil engineering aspects associated with the design and construction of new roadways/street corridors and sections and/or reconstruction. Those aspects include geometric design, pavement design, subsurface drainage (curb, gutter, and open ditch), pavement markings, construction sequencing, and traffic control device plans.
