Abstract

Road works, caused by road widening, road improvements or maintenance, create significant problems with traffic flow and safety for all passersby - motor vehicle passengers, pedestrians and bicycle riders, as well as workers at the work site.

The large amount of work sites along with the risk of road accidents increase the importance for planning and for regulations that are connected with traffic arrangements at work sites.

Aside safety implications, work sites influence the economy and traffic deriving from heavy traffic, difficulties in pedestrian movement, limited accessibility to the adjacent buildings and especially to commerce on adjacent land-uses.

Temporary work arrangements are carried out at work sites in order to keep the road operating while maintenance or development work is being carried out.

When planning traffic arrangements at work sites, one must be mindful of the set of elements: “man-road-vehicle,” as with all traffic planning, and with various potential conflicts - between traffic flow and safety; motor vehicles and pedestrians; road users and workers, and between them and the roads’ residents and businessmen.  

From the literary survey in this research it is possible to see the disparity between different countries in the world and the way they relate to the subject of traffic arrangements on the roads. One can see that there are countries that are meticulous about all issues pertaining to traffic arrangements and implement clear and unequivocal procedures, and there are countries where the matter is subject to the decisions of local authorities and agencies for each project. 

The objectives of this research were: influence of types of motor vehicle and pedestrian traffic safety accessories for specific traffic situations, with the help of an analysis of the conflicts created by each of the safety accessory options and assessment of their costs.

In accordance with the objectives defined above, a comparative test of the options at a municipal site was conducted - a 600-meter section on Hamaginim Blvd. in Haifa in which three types of safety accessories were positioned in different time periods, for the purpose of separating between two lanes of opposing traffic on a route that is one-way under regular conditions.  

During the experiment, tests were made of the changes that apply to the behavior of motor vehicles and pedestrians and to traffic speed, with reliance on the type of safety accessory separating the two directions of traffic along the length of the boulevard.
