Run-off-road: Crashes where a vehicle leaves the roadway, often due to loss of control, resulting in collisions with objects like trees, poles, or ditches.

Head-on: Crashes where two vehicles traveling in opposite directions collide frontally, typically resulting in serious injuries or fatalities due to the high impact forces involved.

Intersection: Crashes occurring at or near road intersections, often involving vehicles making turns, crossing paths, or running traffic signals, leading to various types of collisions such as side impacts or rear-end crashes.

Casualty count inputs should be annual casualties for all ages and all genders, unless otherwise specified. If the number of fatalities is known but not the number of serious injuries, multiply the fatalities by 15 to arrive at an estimate.

Enter the baseline proportion of existing infrastructure for the specified road type.

Traffic Calming: Measures designed to reduce vehicle speeds and improve safety for pedestrians and cyclists, often including speed humps and narrowed roads, etc.

Sidewalks: Paved pathways alongside roads designated for pedestrian use, enhancing pedestrian safety and mobility.

Divided Highways: Highways with a physical barrier or median separating opposing lanes of traffic, improving safety and traffic flow.

Roadside Barriers: Structures installed along the edges of roads to prevent vehicles from straying off the roadway, enhancing safety by protecting drivers and pedestrians.

Helmet Use Rates: The percentage of motorized two-wheeler riders who wear helmets while riding. Higher helmet use rates are associated with reduced head injuries and fatalities in crashes.

Occupant Distribution by Seating Position: The seat position where vehicle occupants are seated (e.g., driver, front passenger, rear passengers) during a crash. This distribution helps in understanding the risk and injury patterns associated with different seating positions.

Seatbelt Use Rates: The percentage of vehicle occupants who use seatbelts while traveling in motor vehicles. Higher seatbelt use rates are linked to a significant reduction in fatalities and serious injuries during crashes.

Proportion of Casualties in Alcohol-Related Crashes: The percentage of road traffic fatalities and serious  injuries that occur in crashes where at least one involved party had consumed alcohol.

Post-Crash Care: A set of medical and support services provided immediately after a road crash, including emergency medical treatment, transportation to healthcare facilities, and rehabilitation services, aimed at minimizing fatalities and long-term disabilities.
