What is the 'Voorhees law of traffic'?

The 'Voorhees law of traffic' is a term coined by Dr. Conor Boland for his mathematical research explaining why slower cars often catch up to faster ones at traffic lights.

Does math prove slower cars will always catch up?

Math suggests that on average, the spacing between cars remains the same after a single traffic light, and the perceived inevitability is often due to memorable encounters rather than a strict rule.

$Math Explains Why Slow Cars Catch Up$

Dr. Conor Boland from Dublin City University has developed mathematical models to explain why motorists often experience slower cars catching up at traffic lights. His work, termed 'The Voorhees law of traffic,' analyzes how car spacing is affected by traffic light cycles, durations, and initial speed differences.

Boland's findings, published in Royal Society Open Science, indicate that the perceived inevitability of being caught by a slower car is largely due to psychological factors. These recurrent encounters are more memorable, particularly after an attempted overtaking maneuver. The mathematical average suggests that the lead one car has over another often remains unchanged after a single light.

However, the situation shifts in urban environments with multiple traffic lights. In such scenarios, the probability of the slower car catching up at least once becomes statistically near-certain. This has implications for road safety, suggesting that speeding to overtake may not yield a consistent advantage. While assumptions are made, the model offers a useful explanation for this common driving phenomenon.

Math Explains Why Slow Cars Catch Up

Q: How do multiple traffic lights affect the outcome?

With a succession of traffic lights, the probability of a slower car catching up at least once becomes statistically near-certain, unlike the scenario with a single light.
