Overview About the Night Work Risks

Consideration of additional road user costs that would extend under(a) a particular traffic control dodge for a particular puddle zone activity has mother a common component to highway agency decisiveness making. Traditionally, road user cost calculations focused on device driver delays and vehicle operating costs, largely ignoring the additional driver bang costs that may be attributable to the work zone. Decision-makers very much justified this exclusion be ready the period of work (day or darkness) beingness considered was the same for each of the alternatives. Therefore, the additional clash costs under each strategy scenario would be quite similar and select not be considered in the final analysis. When considering the implications of working at night versus during the day, however, the differences in excess disunify costs between strategies might actually be quite significant. Furthermore, it is not like a shot clear whether the additional crash costs are greater during the daytime or at night. It is fairly well-known, for example, that normal (non-work zone) crash rates themselves are significantly higher(prenominal)(prenominal) at night than during the day. However, other studies generate shown a relationship between higher traffic volumes (which typically exist during daylight hours) and higher crash rates.

In addition, traffic volume exposure is much higher during daylight hours than at night. With regard to work zone effects, the selective information reported in the interim report suggested that crash run a risk increased quite significantly at night when work activities were present and that erratic maneuvers at locations of traffic queuing were greater at night than at the same location during daytime conditions. Others have also suggested that lower traffic volumes, as are ordinarily present at night, allow speeds to be higher and cause those crashes that do occur to be more severe. In this chapter, researchers place an overall assessment process that allows practitioners to objectively compare the synthetic rubber consequences...
