Scientists who study near-Earth objects say the collision risk is very real.

What is the overall airline midair collision risk during these 8.5 million flight hours?

In general, the collision risks for orbiting stations are high because of their large size and long stay in space.

The Navigation paradox states that increased navigational precision may result in increased collision risk.

Surveys and collision risk modeling was undertaken as well as a population viability analysis to assess the impact on the species.

Street light stanchions (poles) pose a collision risk to motorists and pedestrians, particularly those affected by poor eyesight or under the influence of alcohol.

They specialise mainly in third party liability cover and insurance of the balance of collision risks not covered by the Company or London insurance markets.

Minimum orbit intersection distance (MOID) is a measure used in astronomy to assess collision risk between astronomical objects.

Precrash systems, also known as forward collision warning systems, monitor the roadway in front of the host vehicle and warn the driver when a collision risk exists.

There is no general minimum speed but drivers are not allowed to drive at an unnecessarily low speed as this would lead to significant traffic disturbance and an increased collision risk.

An expert on planetary impacts and global catastrophes, Boslough's work on airbursts challenged the conventional view of asteroid collision risk and is now widely accepted by the scientific community.

I observed that we had spent all our time on the top runs, and Whistler's lower slopes seem to add little value - overcrowded, icy routes home offering high collision risk, low skiing satisfaction.

It was intended to cover liabilities for loss of life and personal injury and also the collision risks excluded from the current marine policies, particularly the excess above the limits in those policies.

(d) If another vessel is detected by radar alone, and a close-quarters or collision risk is suspected, a vessel should take early and substantial action to avoid the other, but:

ACAS would give out continuous and unnecessary warnings about all aircraft in the vicinity, whereas FLARM only gives selective alerts to aircraft posing a collision risk.

Robert E. Machol attributes the term "navigation paradox" to Peter G. Reich, writing in 1964, and 1966, who recognized that "in some cases (see below) increases in navigational precision increase collision risk."
