1 Intelligence Led Policing in Speed Zones Peter J. Negro

2 Intelligence Led Policing in Speed Zones Conceptual assistance, data analysis and photography was provided by District Chicago Trooper Dave Keltner (Technical Crash Reconstruction Officer). Statistics/Trends are for District Chicago (Cook County) Interstates only.

3 Intelligence Led Policing in Speed Zones Patrolling by driving around vs. Intelligence Led Policing

4 Intelligence Led Policing in Speed Zones Patrolling by driving around vs. Intelligence Led Policing District Chicago continuously analyzes crash data to determine the most efficient method(s) of patrolling

5 District Chicago Statistics Population of District Chicago (Cook County)-5.3 million people Approximately 100,000 calls for service in 2006 Handled approximately 17,500 crashes in 2006 Down from 20,000 in Fatalities in 2006 Down From 48 in 2005 South Sector 17 Fatalities, 28 in Fatalities to date in 2007

6 Traffic Safety Efforts in 2006/2007 Implemented with emphasis on four E s E district wide, with emphasis on the Dan Ryan Expressway Construction Project Enforcement Engineering Education Emergency Medical

7 District Chicago Traffic Safety Goals To change the expectations/culture of drivers Driver behavior vs. engineering/highway design To learn who, what, why, when and where for more efficient and effective staffing Aggressive enforcement in appropriate areas for unsafe drivers Communicate/share data with IDOT for most effective use of engineering improvements Road Safety Assessor Training

25 Data Collection and Analysis District CAD Zone Analysis Separates Interstates by Zone. For example, Interstate 290 contains 24 zones. It classifies types of calls and the time spent on those types of calls. It also classifies total number of calls for service, the average response time, time on scene and total incident hours.

28 Human Data Collection and Analysis Input from Patrol Personnel to Improve High Crash/Fatal Problem Areas An e to all district personnel seeking suggestions to solve problem areas in District Chicago

29 IDOT Historical Crash Data Worked with Priscilla Tobias-IDOT Statewide Safety Engineer to analyze crash data and to work on solutions Continuous communication and strategy sessions Emphasis on engineering improvements Chiefs of Police meeting to offer engineering grants

30 District Chicago Problem Response IL 394 south bound from 183 rd to Glenwood/Lansing Road. There is a curve to the left just south of 183 rd that has proven to be a fatal spot. As the road curves, vehicles go off the roadway into the right ditch and strike a tree, resulting in death. I have reconstructed two fatals there, but have known that many, possibly 10 fatals have occurred there, mostly southbound with some north bound crossover.

31 Illinois 394 south bound Fatal Area

32 Several similar fatals on 394

33 IL 394 South Bound

34 Illinois 394 south bound

35 Illinois 394 south bound

36 Illinois 394 south bound

37 183rd Glenwood Lansing Road

38 Recommendation My first suggestion is a guard rail, not cable rail, be installed on the right lane south bound shoulder from 183 rd to Glenwood/Lansing Road. Second would be cable rail placed in the median along the same points to assist with crossover crashes.

39 District Chicago Problem Response We have had numerous serious injury crashes, including fatals, on the ramp from I-80 I east bound to I-57 I north bound.

40 Ramp from I-80 I e/b to I-57 I n/b

41 Ramp from I-80 I e/b to I-57 I n/b

42 Ramp from I-80 I e/b to I-57 I n/b

43 Ramp from I-80 I e/b to I-57 I n/b

44 Recommendation Add signage and a guardrail from I-80 I east bound to I-57 I north. Additionally, rumble strips/stripes to slow cars down would help (Problem Oriented Policing Project).

46 Traffic Safety Strategies

47 Traffic Safety Efforts Enforcement Multi-Disciplinary Approach District Chicago crash/crime information is provided to sector lieutenants/master sergeants for Crash/Fatal/Crime reduction planning with emphasis on Directed Patrols Sector lieutenants and Platoon Master Sergeants continuously plan and schedule directed patrols and special details in District Chicago

48 Directed Patrols Generally consists of two or more officers and one or more hours duration The officers will be assigned to a specific location with special attention to specific focus

49 Directed Patrols Fatal Five (speed, DUI/Alcohol, occupant restraint, improper lane usage, following too closely) Seat Belt Enforcement Zones Criminal Patrols (CrimPat) Drugs, guns, stolen cars, warrants Teen Directed Patrols Driving Under the Influence Tag Team Operation Patrol Platoon 6-Eisenhower/Stevenson 6 Expressways Move Over-Scott Scott s s law

50 Traffic Safety Efforts Truck details on Interstates, including portable scales, inspections and left lane details Speed Motorcycle Enforcement Details Photo Radar Enforcement Van District Wide Directed Patrols Airspeed Labor Day Detail Major emphasis on SBEZ details on Dan Ryan to re-educate educate public

51 District Chicago Enforcement Results 2006 Personal Injury Crashes-845 Fatal Crashes/Fatalities-40/41 DUI Arrests-1,286 Seat Belt Citations-15,699 Speed Citations-12,464 Total Citations-79,156 Speed Written Warnings-12,854 Total Written Warnings-53,043 Firearm Recoveries-56 Criminal Arrests-1,628 Currency Seized-$1,128,318.00

52 IDOT Grants Illinois Department of Transportation provides a variety of grants for: Speeding, DUI, Seatbelt, Motorcycles, Photo Radar Van Adds extra personnel for patrol Crash/arrest data is analyzed and details are prioritized and scheduled Holidays Special Events Areas with high DUI activity (arrests) or fatal/serious injury crashes

53 Education Traffic Safety Efforts School Programs and Prom Demo Multi-agency press conferences with IDOT and various information provided to media Photo radar, Motorcycle, Dan Ryan Project (Discovery Channel), Stay Alive on the I s I media stories Work closely with the local community Constant updates/enforcement information on Electronic Message Boards

54 District Chicago Safety Education Officer Works with local agencies to assist with education and enforcement Car Seat Details Berwyn/Cicero Seat Belt Enforcement Zones South Suburban Association of Chiefs of Police School Zone Details

55 Traffic Safety Efforts Emergency Medical Critical Incident Response Plan-Dan Ryan Expressway Construction Project Plan developed by ISP, IDOT, CPD and CFD Rehearsed prior to start of project Complicated due to the elimination of shoulders on the Dan Ryan Expressway Cooperative effort with local hospital helicopters

56 Conclusion Traffic Safety is successful due to the Cooperative effort between the ISP and the Illinois Department of Transportation Weekly meetings Communication Collective, team effort
