District 10 Mobility Performance Report

2018 First Quarter

EXECUTIVE SUMMARY

Overview

Caltrans District 10 contains eight counties located within the Central Valley (San Joaquin /

Stanislaus / Merced) and the Sierra Nevada (Amador / Calaveras / Tuolumne / Mariposa /

Alpine). Over the years detection in Alpine and Calaveras Counties has been sparse, so the

District 10 Mobility Performance Report (MPR) no longer includes these two counties in the

quarterly or annual analysis.

The MPR quarterly analysis compares information in the current quarter to that of the previous

quarter and the quarter one year prior. The following are the performance measures reported in

the MPR:

Vehicle Miles Traveled (VMT)

Vehicle Hours of Delay (VHD)

Lost Lane Miles (LLM)

Detector Health (DH)

This information is based on data collected every day of the quarter, twenty–four hours a day, by

automated vehicle detector stations deployed on urban-area freeways where congestion is

regularly experienced. The MPR presents congestion information at two speed thresholds: delay

from vehicles traveling below 35 miles per hour (mph), and delay from vehicles traveling below

60 mph. The delay at the 35 mph threshold represents severe congestion while delay at 60 mph

represents all congestion, both light and heavy. These thresholds are set by Caltrans and are

based upon engineering experience and District input.

FINDINGS

In the first quarter, total delay equaled 208 thousand vehicle hours of delay (VHD) at the 35 mph

speed threshold, and 781 thousand VHD at the 60 mph threshold. Compared to the same quarter

the year before, there was a 151.2 percent increase in 35 mph quarterly delay and 37.7 percent

increase in 60 mph quarterly delay. The average weekday delay experienced in this quarter was

approximately 2,900 VHD at 35 mph, and 11,036 VHD at 60 mph. The increased delay numbers

mainly attributed to 35 percent increase in number of good detectors compared to the first

quarter of 2017.

The following District 10 projects are currently being constructed or are scheduled for

construction effective February 2018. These current and future (planned) projects will further

relieve congestion in District 10:

STANISLAUS COUNTYSTA 99 / SJ 99 RAMP METERING & MAINLINE IMPROVEMENTS; EA 10-1C300Improve Mainline and Ramp Operations; Standardize Structure Clearance; Add Auxiliary LaneCurrently in PA&ED End Project – Estimated to be mid 2020

The above capacity increasing, ramp metering, interchange improvement, and interchange construction projects are located on the routes, in the cities, and in the counties that experience the most congestion in District 10. It is expected that the projects will help increase the Vehicle Miles Traveled while reducing congestion and delay as the population and demand in District 10 grows over the next 10 years.

The next section of this report summarizes the District 10 2018 first quarter Quarterly Mobility Statistics.
