Pedestrian Fatalities in Illinois
Pedestrian Serious Injuries in Illinois
Pedalcyclist Fatalities in Illinois
Pedalcyclist Serious Injuries in Illinois
Urban crashes tend to be intersection, pedestrian and bicycle Pedestrians represent 14% of all fatalities and serious injuries
IL SHSP Pedestrian Objectives Reduce vehicle speed Reduce exposure to vehicular traffic Improve visibility between motor vehicles and pedestrians Improve pedestrian and motorist safety awareness and behavior Provide guidance to planners and designers to address pedestrian safety issues
IL SHSP Pedalcyclist Objectives Partner with local, state, and federal agencies and organizations on pedalcyclist safety Improve education of roadway users to improve interactions in traffic Research, identify, and implement policies to improve pedalcyclist safety at the state, local, and government levels Improve infrastructure features to help reduce the number and severity of pedalcyclist crashes using context sensitive approach to design
90% of the pedestrian and bicycle fatalities in Illinois occur in urban areas Almost 70% of the pedestrian fatalities and serious injuries have occurred in the Chicagoland area (Cook, DuPage, Will)

Bicycle Signals A bicycle signal is an electrically powered traffic control device tha should only be used in combination with an existing conventional traffic signal or hybrid beacon.
Bicycle Lanes, Pedestrian Refuge Islands
Refuge Island with Proper Signing Refuge Island: CMF = 0.54 Crash Type Improvement = All Notice additional features FHWA Proven Countermeasure
Pedestrian and School Crossing Signs Advance warning Sign: CMF = Will Vary Crash Type Improvement = Will Vary
Pedestrian Countdown Signals and Controls Pedestrian Countdown: CMF = 0.30 Crash Type Improvement = PED Pedestrian Control: CMF = 0.75 Crash Type Improvement = PED & PDC
Signal Phasing Leading Pedestrian Interval 3 to 7 second head start CMF = 0.63 Crash Type Improvement = PDC & PED FHWA Proven Countermeasure All Red Phase Clears traffic within the intersection prior to green phase beginning. Evaluated to increase the yellow phase to allow vehicles more time to clear intersection.
Improve Intersection Lighting Intersection lighting: CMF = 0.88 Crash Type Improvement = All nighttime crashes
