2003 journal article

Determining traffic stream impacts of radar detectors using microscopic simulation

Journal of Transportation Engineering, 129(1), 7–15.

By: M. Oliveira, B. Williams*  & J. Leonard*

TL;DR: The case study shows that the efficacy of using radar as a speed reduction strategy is a function of congestion and radar detector density, with the strategy being most effective for volumes levels between 200 and 1,400 vehicles per hour per lane. (via Semantic Scholar)

2003 article

Factors influencing faecal contamination in coastal marinas

WATER SCIENCE AND TECHNOLOGY, Vol. 47, pp. 199–204.

By: M. Sobsey *, R. Perdue n, M. Overton n & J. Fisher n

author keywords: boats; faecal coliforms; faecal contamination; marinas; pollution
TL;DR: Levels of faecal coliform (FC) bacteria in marina waters exceeded the standards and guidelines for shell-fishing and primary contact recreation waters and shellfish and greater consideration of human health risks from enteric microbes in marinas waters andshellfish is recommended.

2003 journal article

Modeling and forecasting vehicular traffic flow as a seasonal ARIMA process: Theoretical basis and empirical results

Journal of Transportation Engineering, 129(6), 664–672.

By: B. Williams n  & L. Hoel*

TL;DR: The theoretical basis for modeling univariate traffic condition data streams as seasonal autoregressive integrated moving average processes as well as empirical results using actual intelligent transportation system data are presented and found to be consistent with the theoretical hypothesis.
