PHILADELPHIA, PA (TRAFFIC DATA COLLECTION) - Rodriguez Consulting LLC (Rodriguez) was retained by Sam Schwartz Engineering to provide traffic data collection, data analysis and quality control/quality assurance on the Spring Garden Street Greenway project. This project was led by the Pennsylvania Environmental Council (PEC) to develop a plan to connect Philadelphia’s growing trail networks, and to connect Philadelphia’s two riverfronts.
Rodriguez coordinated and managed manual turning counts (TMC) at seven (7) intersections along Spring Garden Street. The scope of services included:
- Coordination – Utilized Google Earth Pro and field reconnaissance to develop a plan to safely and effectively collect turning movement data on this heavily travelled arterial. Route included a 6-way intersection and an intersection that involved a heavily-used subway station.
- Turning Movement Counts (TMC) - were completed during peak traffic hours on a typical weekday. Intersection recordings identified the following modes of travel: cars, buses, trucks, bicycles, and pedestrians. Jamar TDC-12 count boards were utilized to collect data.
- Data Processing - Data was processed with Jamar PETRA PRO software and exported to MS Excel and Adobe PDF formats for further quality control and analysis. Intersections were video taped for signal timing and to review lane configurations.
- Quality Assurance – Additional counters were utilized for Data Verification. Analysts reviewed data to determine (based on local knowledge and field observations) any probable causes of the discrepancies.
