Summary
The first step to conducting any traffic-related analyses (development impact, signal warrant, crash data, etc) includes the collection of existing traffic information. AMT's project experience in rural and urban areas has shown the importance of collecting all available existing information throughout a project corridor. This can be accomplished through extensive field investigations, as well as the collection of traffic volumes and previously approved traffic/transportation studies.
AMT's extensive field investigations and traffic data collections include the following (but are not limited to):
- Planimetric data (lane widths, turn lane lengths, etc),
- Pavement markings (type and location),
- Existing lane use and traffic controls, including signal timings and phasing,
- Existing peak hour traffic turning movement (if recent counts are not available) that include vehicular, pedestrian, bicycle, and transit counts as necessary,
- Existing traffic control signs and parking restrictions,
- Identification of any congested and bottleneck situations to determine approximate queues and delays to synchronize the existing conditions models accurately.
- Speed limits,
- Pictures of all approaches at the study intersections,
- Existing land use and right-of-way in the vicinity of the project,
- Location of transit facilities and services, as well as location of bicycle facilities,
- Collection of existing crash data (3- or 5-years),
- Curb and gutter data,
- Location of sidewalks, sidewalk ramps, crosswalks, pedestrian signals, and driveway aprons, etc.
This existing field information listed above can then be utilized to provide traffic/transportation analysis and design services to address the specific concerns relating to a project.
Traffic Engineering services generally include
- Manual and Machine Traffic Counts
- Capacity Analysis
- Corridor Analysis
- Delay and Queue Studies
- Accident Analysis
- Signal Warrant Analysis
- Signal Design
- Traffic Calming Design
- Transportation Networking Modeling
