Like everything else, state’s transportation system likely to suffer due to COVID-19

If Mississippians aren’t driving, they are not buying as much gasoline, resulting in a reduction in revenue from the tax on gasoline.

It is too early to see actual data, but it is highly likely that among the many negative impacts of the COVID-19 pandemic, including the tragic loss of life, will be to Mississippi’s highways and bridges.

The primary source of revenue for Mississippi’s Department of Transportation is the state’s 18.4-cent per gallon tax on motor fuels, primarily gasoline.

With the state under a shelter-in-place order, it is logical to assume Mississippians are not driving as much. And if folks are not driving, they are not buying as much gasoline, resulting in a reduction in revenue from the tax on gasoline.

If people are not driving as much, it also could be logical to assume damage is not being done to the state’s infrastructure system.

Tesla stocks surges due to strong vehicle delivery numbers in Q1 [Video] [Video]

Tesla shares are up nearly 17% after the automotive company announced that it delivered roughly 88,000 cars in the first quarter of 2020. Yahoo Finance’s On The Move panel discusses.

Video Transcript

JULIE HYMAN: And we’re watching shares of Tesla, which are up about 5 and 1/2%, even as we see stocks overall decline. This is after the electric carmaker said it had delivered 88,400 vehicles in the first quarter of this year, and that was ahead of– of projections. So let’s talk about this with our panel right now, Rick Newman, somebody who watches the car industry closely. So, Rick, production is really something that has bedeviled Tesla at times, so I guess this is reassuring on that front.

RICK NEWMAN: Yeah, these numbers come with an asterisk, like everything related to the car industry and so many other industries right now, because Tesla was of course, affected. They

Air pollution and health risks due to vehicle traffic

Abstract

Traffic congestion increases vehicle emissions and degrades ambient air quality, and recent studies have shown excess morbidity and mortality for drivers, commuters and individuals living near major roadways. Presently, our understanding of the air pollution impacts from congestion on roads is very limited. This study demonstrates an approach to characterize risks of traffic for on- and near-road populations. Simulation modeling was used to estimate on- and near-road NO2 concentrations and health risks for freeway and arterial scenarios attributable to traffic for different traffic volumes during rush hour periods. The modeling used emission factors from two different models (Comprehensive Modal Emissions Model and Motor Vehicle Emissions Factor Model version 6.2), an empirical traffic speed–volume relationship, the California Line Source Dispersion Model, an empirical NO2–NOx relationship, estimated travel time changes during congestion, and concentration–response relationships from the literature, which give emergency doctor visits, hospital admissions and mortality
