These roadways have been constructed as a reliable means to link cities and towns. Over the years, towns centers and residential housing have developed along these routes changing the characteristics from a roadway that provides mobility into a roadway that provides accessibility to the local population. Consequently, the roadway infrastructure has not always evolved to meet the demands of the population living closest to the road, instead serving others located outside the town. Road diets, or lane reductions, have been introduced to help mitigate crash incidents, while creating a corridor that can provide greater accessibility to pedestrians and bicyclists. This research compares the characteristics of two parallel corridors, 4-lane Route 31 (NJ-31) and 2-lane Route 206 (US-206), located in Mercer County, New Jersey (NJ), US. Both roads traverse residential areas and are in close proximity to a college campus. NJ-31 has the potential to be reduced from 4-lanes to 2-lanes, but information is needed to support this reduction. An analysis of the two corridors including crashes, congestion, volume, demographics, and entrance types are quantified and compared. Although similar in traffic volume, the NJ-31 experiences a higher rate of traffic crashes per mile, while US-206 experiences more congestion. This research demonstrates a foundation in establishing metrics to determine long term impacts of a dieted roadway, and to quantify an increase of congestion as compared to a reduction in crash incidents.</p> Rachel Hannah Thomas Brennan Seri Park Copyright (c) 2023 Journal of Modern Mobility Systems https://creativecommons.org/licenses/by-nc-sa/4.0 2023-12-23 2023-12-23 4 101 108 10.13021/jmms.2023.3675 https://journals.gmu.edu/index.php/jmms/article/view/3952 <p>Current intersection sight distance design parameters may not adequately accommodate horse-drawn vehicles which are present in significant numbers in some rural areas of the United States. This study examined the intersection sight distance case for two-way, stop-controlled intersections (stop on the minor road) for horse-drawn vehicles. The eye height of a horse-drawn vehicle driver was found to average 5.8 feet, noticeably higher than the standard value used for passenger cars, but less than that used for trucks. The stopping position of horse-drawn vehicle drivers was found to be further from the edge of travelled way of the major road than for motorized traffic, at an average distance of 27.2 feet. Analysis of accepted and rejected gaps for left turns, right turns and crossing maneuvers suggests that the critical gaps for horse-drawn vehicles are noticeably longer than for either passenger cars or trucks and range from 12 to 14 seconds.</p> Jay Grossman Charles McKenzie Ignacio Veloz Copyright (c) 2023 Journal of Modern Mobility Systems https://creativecommons.org/licenses/by-nc-sa/4.0 2023-12-26 2023-12-26 4 109 114 10.13021/jmms.2023.3952
