Because the roadway construction site is a part of the manmade
placement areas, its influence on the safety of road users and
constructors is very great. Any carelessness will cause
casualties and further result in such problems as
indemnification. Therefore, it is necessary to make a further
study and analysis for the placement of traffic safety
facilities in the roadway construction site as a reference for
the planning of related domestic safety measures. In Taiwan, the
use of traffic maintenance facilities is very popular in the
current roadway construction environment. However, there is not
any complete placement standard & principle nor any domestic
data about its result for reference.
For the result of traffic maintenances, this research will study
it from three aspects including safety, cost and standard. For
the aspect of safety, we will analyze the result of traffic
maintenances during the roadway construction period and also
make a statistic analysis as a reference for drivers and
constructors in the future. We also study if the result of
long-term traffic maintenances on site would be obviously
changed over time. For the aspect of cost, this research will
analyze the marginal cost and the cost benefit of among various
traffic maintenances during the roadway construction period to
make the construction unit efficiently understand the relation
among various traffic maintenance costs and have a better
allocation choice under the limited cost. For the aspect of
standard, with the traffic maintenance project for the
experimental site and our actual observations, we will check the
essentials of traffic maintenance placement item by item,
complied by the Directorate General of Highways, M.O.T.C., to
understand if there is any inadequate or it is necessary for
improvement. And with the comparison between our speed limit
regulations in the construction area and those of other advanced
countries, we will study if there is any inadequate or further
improvement for the speed limit standard in roadway construction
areas provided by domestic laws & regulations. Through the
analysis of safety, cost and standard, we can provide the
construction units a better and more effective suggestion for
their traffic maintenance placements. |
