Safety Management System for Israel

Transcription

1 Safety Management System for Israel Dr. Simon Lewis and Joe Garvey AgileAssets, Inc. Traffic Records Forum New Orleans July 27, 2010

2 A nation under pressure * Do things well /smart * Do things right first time! * Integrate! 2

3 SMS Vision: Safety Goals.. strives to provide a safe and wellmaintained transportation system that meets the needs of the traveling public and supports the development of sustainable, vibrant communities... 3

4 SMS Challenge: Integration-Leverage the Existing! ES: AgileAssets Advantage: Leverage Existing Projects Technology Data Leverage Existing Implementation Projects Business Processes Organizational 4

5 SMS Integration Modular Framework Pavement Analyst Bridge Analyst Executive Decisions Safety Management System Maintenance Manager Fleet, Equipment, Materials, Labor Core AgileAssets Functions Asset Inventory Base Linear Reference Security User Organization Terminology Data Management Reporting Graphing Communications System Utilities Common Data Model External Systems (e.g., SAP. Advantage, PeopleSoft., etc) LRS Network Data Manager Mobile Data Collection GIS 8/12/2010 AgileAssets Inc. 5 5

6 Working with SMS Identification of hazardous sites crash data and road data In-depth investigation per section/junction Results of the models Identification of deficiencies Selection of treatments Production of an annual work plan for sections and junctions 8/12/2010 AgileAssets Inc. 6 SMS 6

7 What a SMS Does Highlights of a crash system Crash Database Inventory (e.g., Signs, Obstacles, Guardrail, Trees, Road Markings, etc ) Road Feature (e.g., grade, width, number of lanes, speed, etc ) Reactive Models ( after the crash ) Proactive Models ( before the crash ) Hot Spot Identification e.g., Top 5% Project Composition (check lists and manual) Network Analysis Set of Standard and Customized Reports 7

8 Data Import Import is used: To acquire new geometry from the map To receive data & then return it in all LRMs

9 Data Cleansing Approach: Data Import /Validation/Cycle 9 February 8, 2010 AgileAssets Inc. 9

10 Road Condition Reporting Capability

11 LRS: Data Centric & GIS Centric

12 Alternate LRS s

13 Road Attributes

14 SMS Software Functionality Setup Reports Data Detailed investigationproject level Analysis for the entire network 14

15 Case Study Example To Address each Geometric Deficiency, on each Route-Section Recommend Treatments Combine Treatments to Compose Project SECTION PROJECTS TREATMENTS 15

16 SUPPORT FOR MULTIPLE LRM s 16

17 Reactive and Pro-active Models Reactive Models: Over-representation compared to a group s average Examples: Crashes at night, Collision with still object, Driving off the road or onto sidewalk, Front to Rear, Etc. Proactive Models: Evaluation of engineering problems already present Examples: Difference between Required and Existing lane width, Improper internal shoulder width, Improper height of roadside barrier, Etc 17

18 Reactive Models 1 Over-representation compared to a group s average Examples: Crashes at night Collision with still object Driving off the road or onto sidewalk Front to Rear Collision with Parked Vehicle Pedestrian Etc 18

19 Reactive Models 2 % Group % Site Over-representation score 19

20 Proactive Models 1 Proactive Models Evaluation of engineering problems already present Example: Difference between Required and Existing lane width Improper internal shoulder width Improper height of roadside barrier Difference between Limit and Design Speed Speed Consistency Lack of recovery area Etc 20

21 Proactive Models - Approach Analysis of Performance Measures to Identify Needs - Recommend Treatments Proactive Models Reactive Models Safety Data Roadway Features Black Spots Detection (Reactive) Safety Deficiencies (Proactive) Network Safety Needs Budget Constraints Prioritization Safety Work Plan 21

22 Proactive Models Segment on Section Proactive Model Severity 22

23 Case Study - Example NC Division 5 : Safety Analysis Report Proactive Model Score Number of Sections Less Than 1 2,863 Between 1 & Greater Than 2 57 Total Number of Sections 3,266 Higher the Proactive Model Score More Safety Needs / Treatments Required 23

24 Case Study - Example For each Geometric Deficiency, on each Route-Section, Determine Extent of Severity, & Calculate Proactive Model Score 24

25 Case Study - Example For each of the 3266 Sections, Analyze Inventory: County, Route, Mileposts, Direction etc. Crash History: Number of Crashes, Crash Rate, Crash Frequency by Severity and Crash Type, based on Performance Measures Geometric Deficiencies, based on Performance Measures 25

26 Model Parameters: Treatments

27 Case Study - Example Select Optimal Set of Treatments / Projects Maximize Benefits Based on Budget Constraints Scenario Needs Needs Addressed with Budget Cost Economic Benefits Benefit / Cost Ratio Unlimited Budget 65 Sections 580 Treatments 65 Sections 580 Treatments $25 M $95 M 3.80:1 Limited Budget - $16 M 65 Sections 580 Treatments 47 Sections 353 Treatments $15 M $43 M 2.87:1 Limited Budget - $10 M 65 Sections 580 Treatments 32 Sections 226 Treatments $9.8 M $29 M 2.96:1 Optimal Set of Treatments to Maximize Benefits, Given Limited Resources Safety Management : High B/C Ratio, even with a Lower Budget, by selecting Optimal Set of Treatments 27

28 Master File Reactive models results Summary of the Proactive models result Hot Spots Result Average No. of Crashes over last 3 28 years

29 Hot Spots Potential for Safety Improvements Deficiency Sites SUM PSI >2 Potential for Safety Improvement 29

30 Case Study - Example For each of the 3266 Sections, Analyze Inventory: County, Route, Mileposts, Direction etc. Crash History: Number of Crashes, Crash Rate, Crash Frequency by Severity and Crash Type, based on Performance Measures Geometric Deficiencies, based on Performance Measures 30

31 Israel SMS

32 Conclusion Israel wanted to do this right from a wider agency perspective Many agencies (workgroups) have had a grow your own SMS strategy Wider agency integration issues (PMS, MMS) to be asked to gain maximum SMS: Utility Cost efficiency Agency benefits Integration a key concern if not to be duplication in costs: Training Software acquisition Support costs Data re-use 32
