Project Goal

• Take the outputs of recent research and guidance on the standardized collection and reporting of TIM performance to the next level by conducting a pilot project that will highlight and further guide the implementation of TIM performance measurement nationally.

4

Technical Objectives

• Benchmark practices in TIM performance data collection, analysis, and reporting in Nevada against those of peer agencies.

• Assess the quantity and quality of incident data currently available across the state.

• Provide options/recommendations for filling data gaps.• Build and populate a prototype statewide TIM

database and dashboard.

5

Overview of Approach• Leverage and apply the findings and outputs from recent research:

– Interviews with TIM agencies– NCHRP 07-20 Guidance for Implementation of TIM PMs– TIM PM data check list

• Conduct a gap analysis between:– Current practices in Nevada and those of peer organizations– Incident data currently available in Nevada and the minimum TIM performance

reporting needs (for national TIM PMs) – Incident data currently available in Nevada and the data elements needed to

populate the NCHRP 07-20 TIM PM data model

• Engage the Northern and Southern Nevada TIM Coalitions• Use an open source database and cloud service • Integrate incident data from multiple sources (beyond transportation)

6

Leveraging Recent Work and Gap Analysis

• Leverages both the TIM PM data model and the TIM PM check list of data elements.

• Data gap analysis– Incident data currently available

vs minimum TIM performance reporting needs

– Incident data currently available vs data elements needed to populate the TIM PM data model

Integrating Data from Multiple Sources

• Illustrates magnitude of the incident data overall and the overlap in data between the agencies (not to scale).

• Considered hand-in-hand with the assessment of the data sources (e.g., having the most data is not necessarily “best”).

• NHP/NDOT crash data, combined with the NHP CAD data and the FSP data, will provide the most comprehensive look at TIM performance.

Example – Overall Number of Incidents

Traffic Incidents from FAST TMC (Las Vegas)

Traffic Incidents from Nevada Highway Patrol (Las Vegas)

Traffic Incidents from Nevada Highway Patrol – Statewide

Expected Benefits• Improve the availability and consistency of incident data

statewide.• Improve TIM performance reporting in Las Vegas by increasing

the overall number of incidents included in the analysis (beyond current coverage area and times) and the details associated with the incidents.

• Enable NDOT to report on TIM performance in areas beyond Las Vegas – STATEWIDE.

• Through the database and dashboard, provide NDOT and the TIM Coalitions with detailed information on performance, as well as situations/areas where performance could be improved.
