Air pollution in Bucks County is currently terrible (Cite for example, the 2025 State of the Air by the American Lung association. Bucks County receives a failing grade. There is a considerable body of research demonstrated that cars – and trucks even more so – are a significant source of air pollution which is linked to many health problems such as asthma, other respiratory conditions, reduced lung function – even increased rates of myocardial infarction, progression of atherosclerosis, and cardiovascular mortality. Diesel exhaust from trucks and buses has even been classified by the World Health Organization (WHO) as carcinogenic to humans – even at low levels and in short-term exposures.

PennDOT’s traffic count data from February 2024 showed 8 heavy trucks and 104 buses/single unit trucks (or 112 total trucks/buses) in the morning peak hour and 6 heavy trucks and 49 buses/single unit trucks (or 55 total trucks/buses) in the afternoon peak hour.

PennDOT’s online traffic count data from 2024 indicates 3% truck traffic and 511 total trucks and buses per day along PA 413 (Pine Street) north of the intersection and 12% trucks and 1522 total trucks and buses per day along PA 413 (Pine Street) south of the intersection. 

The traffic data from 2024 stated above, which is similar to previous counts, is the traffic data currently being used in the project traffic analysis.  At no point in time during the project’s traffic analysis were the truck numbers referenced by Langhorne Borough used to evaluate any proposed alternatives.
