TMC ATSPM Data Analysis

Overview

'TMC ATSPM Data Analysis' carries out Automated Traffic Signal Performance Measures (ATSPM) and supports objectives and performance-based traffic signal operations, maintenance, and management. It collects high resolution (Hi-Res) signal controller and cabinet events data and uses this information to measure traffic signal performances and identifies maintenance issues for signal system infrastructure. It also suggests signal timing plan and can be passed to the TMC so that the signal timing suggestions can be reflected in future signal retiming activity. It provides an interface to traffic operation personnel and disseminates signal performance measure reports, charts and identified signal system infrastructure maintenance issues, including approach delay, approach speed, arrivals on red (AoR), and Purdue Coordination Diagrams (PCD). This functional object can be implemented either as an integrated module of the Advanced Traffic Management System (ATMS) or as a separate software application. The ATSPM application may be executed in another center and shared with the host center.

This functional object is included in the "Traffic Management Center" physical object.

This functional object is included in the following service packages:

• TM03: Traffic Signal Control

This functional object is mapped to the following Functional View PSpecs:

• 1.1.4.2: Provide Traffic Operations Personnel Traffic Data Interface
• 1.1.5: Exchange Data with Other Traffic Centers
• 1.2.1: Select Strategy
• 1.2.4.1: Output Control Data for Roads
• 1.2.6.2: Provide Static Data Store Output Interface
• 1.2.6.3: Configure Roadway for Performance Measures
• 1.2.6.4: Collect and Store Signal Performance Measures

Standards

Currently, there are no standards associated with the functional object itself though the interfaces may have standards associated with them.
