Road Safety Calculator

Annual Motor Vehicle Occupant Casualties in Cars, Vans, SUVs, and Light Trucks Only: The total number of deaths and serious injuries sustained by occupants of cars, vans, SUVs, and light trucks within a year.

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 severe injuries during crashes.

Annual Motorized Two-Wheeler Casualties (Age 15 and above): The total number of deaths and serious  injuries sustained by riders of motorized two-wheelers (age 15 and above), such as motorcycles and scooters, within a year.

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.

Helmets Meeting Safety Standards: The percentage of helmets that comply with established safety regulations and standards, such as DoT or ECE 22.05, etc. These standards ensure that helmets provide adequate protection in the event of a crash.

Annual Road Crash Casualties (All Road Users): The total number of deaths and serious injuries sustained by all types of road users, including drivers, passengers, pedestrians, cyclists, and motorcyclists, within a year. 

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.

Annual Pedestrian Casualties on Roads with Speeds Less Than or Equal to 50 km/h: The total number of deaths and serious injuries sustained by pedestrians on roads where the speed limit is 50 km/h or lower within a year.

Proportion of Roads with Speeds Less Than or Equal to 50 km/h with Sidewalks: The percentage of roads that have a speed limit of 50 km/h or lower and are equipped with sidewalks. This proportion indicates the extent to which pedestrian infrastructure is provided in lower-speed areas to enhance pedestrian safety.

Annual Road Crash Casualties at Uncontrolled Intersections: The total number of deaths and serious injuries resulting from road crashes that occur at intersections without traffic signals or stop signs within a year.

Annual Head-On Collisions at 80 km/h and Above: Crashes where two vehicles traveling in opposite directions collide frontally at speeds of 80 km/h or higher within a year, typically resulting in serious injuries or fatalities due to the high impact forces involved.

Add Flexible Delineator Posts to Discourage Overtaking in Curves: Adding posts on curves to prevent overtaking and improve safety by marking the lane boundaries.

Add Median Barrier: Adding a physical barrier placed in the median of a road to prevent cross-median collisions and enhance safety.

Add Painted Median on Undivided Two-Lane Road: Adding a visual divider on a two-lane road to enhance safety and manage traffic flow.

Add Two Travel Lanes and Median to Existing Urban Arterial: Adding a median to a two-lane urban arterial road to separate opposing traffic flows and reduce crashes.

Convert Existing Undivided Two-Lane Road to 2+1 Road: Converting a two-lane road to a 2+1 configuration involves adding an additional lane in one direction to improve traffic efficiency and safety.

Install Centerline Rumble Strips: Installing raised strips along the centerline of a road that alert drivers to potential lane departures and reduce head-on collisions.

Annual Run-Off-Road Casualties on Roads with Operating Speed of 80 km/h and Above: Crashes where a vehicle leaves the roadway at speeds of 80 km/h or higher within a year, often due to loss of control, resulting in collisions with objects like trees, poles, or ditches.

New Barrier: Installation of a newly designed safety barrier on roads to prevent vehicles from veering off the road and to protect against collisions with hazards.

Conversion to Softer Barrier: Upgrading existing barriers to more forgiving, impact-absorbing barriers that reduce the severity of crashes and protect occupants.

Hazard Removal: The process of identifying and eliminating roadside obstacles or dangers, such as trees or signposts, to reduce the risk of run-off-road crahses.

Annual Motorized Casualties at High Speeds: Motorized casualties on roads with speeds of 80 km/h or higher within a year. Crashes on high-speed roads often involve serious injuries or fatalities due to the high impact forces in collisions.

Operating Speed: The average speed at which vehicles travel under typical conditions on a road segment. It reflects the speed chosen by drivers based on road design, traffic flow, and environmental conditions, but excludes factors that are not directly related to road design or driver behavior, such as congestion, weather conditions, and road surface quality.

Annual Road Crash Casualties (All Road Users) on Roads with Speeds Less Than or Equal to 50 km/h: The number of serious injuries or fatalities resulting from traffic accidents on roads where the speed limit is 50 km/h or lower within a year.

Proportion of Roads with Speeds Less Than or Equal to 50 km/h Equipped with Traffic Calming Measures: The percentage of such roads that have been modified with design features aimed at reducing vehicle speeds and enhancing safety.

Annual Road Crash Casualties (All Road Users): The total number of deaths and serious injuries sustained by all types of road users, including drivers, passengers, pedestrians, cyclists, and motorcyclists, within a year.

Proportion of Fatalities That Occurred Instantly at the Scene of the Crash: The percentage of road crash fatalities where the victim died immediately or within a very short time frame at the accident site, as opposed to dying later from injuries in the hospital or other circumstances.
