ASTM E2667

ASTM E2667 is the ASTM standard practice for acquiring intersection turning movement traffic data, providing a consistent framework for collecting roadway movement information at intersections. It helps transportation professionals capture turning patterns in a structured way, supporting more reliable analysis, planning, and operations work. By defining a common practice for data acquisition, ASTM E2667 can improve comparability between studies and reduce variation in how intersection traffic counts are gathered and reported.

Purpose of ASTM E2667

The purpose of ASTM E2667 is to guide the collection of turning movement traffic data at intersections in a way that is systematic and usable for technical evaluation. As a standard practice, it focuses on how data are acquired rather than on design outcomes, making it relevant for teams that need consistent field observations or recorded counts. This structure can help improve the quality of intersection data used in planning, traffic operations, and performance review.

Common use cases of ASTM E2667

This standard is commonly used when transportation agencies, consultants, or traffic engineers need dependable intersection turning movement data for analysis. It may support studies related to signal timing, intersection performance, traffic impact review, and operational planning. ASTM E2667 is also useful when comparing traffic patterns across locations or time periods, since a consistent acquisition method helps make the resulting data more dependable for downstream technical work.

Why ASTM E2667 matters

ASTM E2667 matters because intersection turning movement data are often used as a basis for important traffic decisions. When the collection practice is consistent, the results are easier to verify, compare, and apply in professional workflows. That can support better compliance with project requirements, stronger quality control, and lower risk of using incomplete or inconsistently gathered data. For procurement and review purposes, the standard also gives buyers and users a clear technical reference.
