ITS & ATM Master Plan

The Nevada Department of Transportation (NDOT) has developed an intelligent transportation system (ITS) and active traffic management (ATM) master plan to improve the safety, reliability, mobility, and overall performance of the State’s surface transportation system. “ITS” encompasses traditional ITS devices and equipment and “ATM” strategies encompass active traffic management strategies that in combination provide full coverage of a corridor for detection, visual monitoring, and sharing information with the traveling public. The master plan underwent a process to assess current systems in both the State’s rural and urban areas, identified infrastructure and policy needs, and outlined future ITS and ATM strategies to advance NDOT’s transportation management capabilities. The master plan is in alignment with the NDOT Transportation Systems Management and Operations (TSMO) Program, TSMO Implementation Plan, One Nevada Plan, Transportation Asset Management Plan (TAMP). This master plan also provides NDOT with a clear understanding of how to plan for, implement, operate, and maintain ITS and ATM strategies and devices at a statewide level.

The plan’s recommendations, direction, and integration of recommendations into NDOT’s project scoping process has resulted in the following deliverables for use by NDOT and interested parties:

  • Nevada Statewide ITS & ATM Master Plan

           Technical Memo #1 - Existing Conditions and Inventory

           Technical Memo #2 - Needs and Gaps 

           Technical Memo #3 - Deployment Recommendations 

           Technical Memo #4 - Implementation Plan 

  • Executive Summary

Updates Tools and Resources_ITSandATM Master Plan

A master plan is a multi-step process that provides a strategic vision for the growth and operation of NDOT’s transportation network. This master plan, which was initiated in early 2022 and completed in late 2023, utilized a 4-step process.

 

 

This plan encompasses all of ITS. Although there is recognition that ATM is a key component that NDOT wanted to look at, ATM is just one small component in the broad suite of potential TSMO ITS Strategies. There are 5 focus areas that the plan is based around: Communications, Operations, Partnerships, Data, and Technologies. Each focus area has a goal and objective and each focus area has individual strategies that have been developed for them. Technologies specifically got a data-driven analysis approach looking at the following types of data sets across the entire state:

  • Avg Max Queue Length (RITIS)
  • Congestion (RITIS)
  • Bottleneck Rank (RITIS)
  • Travel Time Index (RITIS)
  • Total Delay (RITIS)
  • Travel Time Reliability (RTITS)
  • Crash Rate/EPDO – weather, wildlife, visibility, wind, snow/rain (Crash Data)
  • Needs of Districts, MPOs, and other partner agencies

The approach taken to develop recommendations seeks to summarize areas where ATM applications could be utilized as well as separate areas where more traditional or innovative data-driven techniques such as simpler applications of cameras or detection could be utilized rather than ATM applications. The three categories of approach are Urban, Urban Lite, and Rural.

Qualitative and Quantitative recommendations have been developed in full alignment with the One Nevada Plan process. Qualitative needs focus on non-numerical data and the identified issues represents a combination of experiences in the state, national trends where the state should leverage opportunities to improve, and sustainable practices that will create long-lasting functions to support the state’s services. Quantitative needs have data that support its identification and therefore are a method to determine data-driven recommendations.

The master plan identified 83 infrastructure project concepts including 40 in District 1, 31 in District 2, and 12 in District 3, as well as 46 ITS support program recommendations by priority areas.

ArcGIS files for quantitative recommendations are available on NDOT’s GeoHub for use in physical infrastructure project scoping along NDOT-owned roadways in the state to support the ITS & ATM Master Plan implementation. ArcGIS files have also been provided to the One Nevada Plan process as well to incorporate influential qualitative recommendations into the programming of future funding.
