About this file

Written by GovTribe AI ·

This Scope of Work attachment document outlines the digital traffic count formats and methodologies required for the City of Fountain Valley's traffic data collection project supporting the 2027 Congestion Management Program (CMP) update in California. The document provides standardized formats for collecting and reporting traffic volume data at CMP intersections, including detailed specifications for two primary data collection systems: the NDS/FDS (Southland Car Counters) format and the JAMAR Comma Separated Variables (CSV) format. The attachment includes sample traffic count data collected on November 1, 2006, at the intersection of Euclid Street and La Palma Avenue in Fountain Valley, demonstrating the required data structure with 15-minute interval counts broken down by direction (northbound, southbound, eastbound, westbound) and movement type (right turn, through, left turn, and pedestrians). The data collection encompasses a full business day from early morning (6:00 AM) through evening hours (5:45 PM), with calculations of peak hour volumes and peak hour factors to support level-of-service analysis.

The document establishes the technical requirements for traffic monitoring equipment capable of capturing vehicle movements and pedestrian activity at signalized intersections. Both the Southland Car Counters and JAMAR systems are specified as acceptable technologies for meeting the data collection standards, with detailed CSV formatting requirements for electronic submission of traffic counts. The sample data demonstrates the granularity expected, with separate tracking of turning movements and pedestrian counts to provide comprehensive intersection performance metrics. These standardized formats enable consistent data collection across all 101 CMP intersections throughout the region, facilitating comparative analysis and supporting transportation planning decisions related to congestion management and level-of-service determinations.
