Intelligent Transportation System (ITS)


What is the Intelligent Transportation System? 

ITS (Intelligent Transportation Systems) is the range of advanced technologies and proven management techniques to improve mobility and transportation productivity, enhance safety, conserve energy resources, and reduce adverse environmental effects. ITS uses real-time information to integrate and manage the components of a conventional transportation system (roads, transit, ramp meters, traffic signals, etc.). ITS helps improve traffic circulation on busy roadways.




How ITS helps you

  • Reduces corridor congestion by rapidly detecting and responding to traffic incidents.
  • Reduces travel times, stops and delays by dynamically adjusting traffic signals in response to changing traffic conditions.
  • Alerts motorists, pedestrians, bicyclists, commercial vehicles, and transit operators of congestion by collecting, processing and disseminating real-time information.
  • Provides real-time transit arrival and departure information to passengers allowing them to time their departure from work or home to the transit stop.

The demand for mobility is often met by building more highways and bridges and adding more lanes to roads and streets in our cities. Although road widening can be very effective in in reducing traffic congestion, additional ways of managing traffic need to be considered to further enhance the efficiency of the roadway network. ITS provides new tools to augment traditional transportation improvements. Deployment of ITS tools and strategies, the next major evolutionary stage of surface transportation, is expected to be the focus of major metropolitan area implementation efforts over the next several years, much like the highway system program was the focus of the last 60 years. Implementing ITS is one of the most cost effective ways to augment a roadway Capital Improvement Program and obtain a more efficient transportation system.

ITS applications represent a significant opportunity to improve the efficiency and safety of the surface transportation system in Roseville. These applications primarily improve the operation of a transportation system by either performing a function faster or more reliably, or by providing a service that was not previously available. In so doing, ITS provides for improved mobility of people and goods on the roadway network.


Tools

Roseville is incorporating other ITS-related components along with the recently upgraded signal system to help reduce the amount of traffic congestion on busy roadways. The City uses this ITS technology with the goal of improving traffic circulation throughout the City as well as to decrease driver aggravation by providing them timely and relevant traveler information. This is accomplished by publishing real-time City traffic congestion, construction, special event, and major traffic incident information via the Internet and on CMS's (Changeable Message Signs).


Real-Time Traveler Information Tool

The City of Roseville’s Traffic Operations Section provides real-time traffic information to the public via the Internet. The real-time information includes traffic congestion levels, incident (accident) and construction activities, as well as links to live video at 100+ intersections throughout the city. In addition, intersection turning movement and volume count data is available at various locations. The purpose of real-time traffic information is to improve roadway operations by providing real-time information the public so that they can make informed travel decisions.


Changeable Message Signs
Another traffic control device that aids in providing motorists with real-time information is changeable message signs (CMS’s). CMS’s located along roadways display real-time information to motorists such as accidents and special events. Providing this information allows the driver to make informed decisions regarding their travel options.

Current CMS locations:
   -  Galleria Blvd. near the Galleria Mall
   -  Washington Blvd. near the Placer County Fairgrounds
   -  Atlantic Street between Yosemite Street and Tiger Way
   -  Riverside Avenue south of Cirby Way
   -  Douglas Blvd. west of Professional Drive
   -  Sierra College Blvd. north of E. Roseville Parkway
   -  Sunrise Avenue south of Cirby Way
   -  Baseline Blvd. east of Fiddyment Road
   -  Foothills Blvd. South of Cirby Way

Future locations:
   -  Blue Oaks Blvd east of Woodcreek Oaks Blvd - Spring 2015
   -  Pleasant Grove Blvd north of Roseville Pkwy - Spring 2015


Bus Tracker
Roseville Transit's Bus Tracker uses GPS technology to track the location of buses, providing estimated bus arrival times online for Local and Commuter routes. See up-to-the-minute maps and arrival times for your bus stop.

How ITS is used to successfully manage traffic incidents
 
Approximately 10,000 vehicles per weekday use the Harry Crabb Tunnel to access eastbound I-80 from Sunrise Ave. Occasionally Caltrans closes this tunnel to perform maintenance, which means vehicles would instead use the Douglas & Sunrise intersection to access I-80.

Douglas and Sunrise is one of the top 10 busiest intersections in Roseville. In order to minimize the impact of a sudden increase in traffic at Douglas and Sunrise, two actions are immediately initiated remotely from the Traffic Operations Center.

First, a message is displayed on the Changeable Message Sign (CMS) on Sunrise Ave. This CMS is located in advance of the tunnel, alerting the motorist of the closure. The motorist can then decide to take an alternate route.

Secondly, the traffic signal at Douglas and Sunrise is modified to give any available time to the northbound approach—without compromising the traffic flow on Douglas Blvd.

Once Caltrans has completed their maintenance, the message displayed on the CMS is removed and the traffic signal timing at Douglas and Sunrise is returned to normal.



ITS Master Plan

The Roseville ITS Master Plan Project was the first step in establishing a fully deployed multi-modal ITS program. Previous project reports defined Roseville’s ITS Concept of Operations which presents strategies for achieving the City's ITS vision, goals, and objectives. This final report built on the ITS Concept of Operations by presenting a detailed deployment plan for implementing the City's ITS strategies. Descriptions of each of the recommended projects along with a preliminary implementation timeline and cost estimate can be found in the ITS Master Plan. In addition, matrices are presented which map each project to specific ITS strategies and geographic corridors.



Roseville ranked in National Traffic Signal Report Card

In June 2012, the National Transportation Operations Coalition (NTOC) released the results of the 2012 National Traffic Signal Report Card. The results contained in the 2012 National Report Card were based on responses to the Traffic Signal Operation Self Assessment. More than 241 state and local governments completed the self assessment and returned the results for compilation into the 2012 National Traffic Signal Report Card. The nation, as an average, received a 'D+' grade, while the City of Roseville received a 'B'.
