3 DATA ANALYSIS For each BS site two parameters are used for the data analysis: 

Annual Accident Rate (AR):



Number of Deaths per hectometer.

The calculus of this rates have been carried out considering the number of the accident and the number of Deaths indicated on the NAR list but taking the length from the database (see the graph of dangerous section). The table shows the Rates and the values used for the calculus. Indicator reference to 2001 – 2006 BS N. 02 Accident Rate Annual accident rate values ( AR ) AR = Accident Daily Traffic lengtht of branch T (years)

Figure Mortality caused by road accidents in Europe (data source: HFA db 2003) Although some actions were taken by the Romanian authorities, the death rate in the last years is quit high (please see above Figure) and is on the first place in Europe with 12,81 rate (Table 2 and Figure). But the sever injuries as consequence of the transportation of the dangerous good increased the last 3 years with almost 40%. Moreover, the accidents rate on the national roads or highways located outside of the cities areas is double that in the cities neighbourhood areas. Most of them from these are with heavy vehicles that transport dangerous goods. Based on national economical development and the political integration in EU in 2007, the road transport will continue to grow with 8-10% per year till 2015. If the accidents rate caused by the transportation of the dangerous goods will follow the same rate, in some years the number of injuries will increase tremendous. The social costs of the traffic accidents in 2003 were estimated at over 350 million euro (about 2 % from PIB), representing the losing of human lives, the expenses for re-covering of the people with physical handicaps, as well as those for financial prejudice.

b.TRAFFIC AND MOBILITY SITUATION There are problems due to the high presence of heavy traffic and to the high speed of traffic.

c. SITUATION CONDITIONS OF THE CARRIAGGEWAY AND SHOULDERS The pavement of the road is in a fair condition but with shoulders only partially paved. On the other hand, there is some small presence of rutting and deformations due to the presence of heavy traffic.

5 SAFETY DIAGNOSIS 5.1

DESCRIPTION OF THE SITUATION

The on-site visit allowed to understand the main safety issue related with this place. There are three main subjects to be treated and resolved: 1. the junctions between DN1B with DJ68 2. the pedestrian crossings 3. the bus station The existing situation is illustrated in the next paragraph. 5.2

Junction

The DN1B intersects DJ 68 and in this junction. The scenario is also affected by the following elements: a. high presence of heavy traffic on DN1B b. inappropriate geometric characteristics for operating speeds: insufficient sight distances c. there are only painted markings and not plastic markings; this cause low visibility especially during the darker seasons of the year and makes regular road woks necessary for repainting. 5.3

Pedestrian crossings

There are not pedestrian crossings in this area.

6 MAIN PROPOSED SOLUTIONS 6.1

Junctions

Taking into consideration the limited amount of space available at this place a possible solution could be based on the improvement of the existing topology. In the annexed scheme the details about this proposal are presented. Furthermore other improvements that should be included are: a. Redesign/remark this junction b. new pavement and paved shoulders on DN 1B and on DJ68 c. integrative signals and markings before the junction (rubber noise bands, flashing signals as notice, etc…) 6.2

Pedestrian crossings Different kinds of solutions should be implemented in parallel as follows: a. improvement of the lightning system, with dedicated lights at each crossing b. integrative signals and markings before the crossings (rubber noise bands, flashing signals as notice, etc…) c. installation of on-demand traffic light systems

6.3

Other improvements Different other solutions should be implemented in the area to improve the safety conditions, as follows: a. eliminating the small irregularities that were observed on DN1B and on DJ68 b. solve the ditches problem c. improve the possibility to turn left/right on the local road without to affect the traffic from the opposite direction d. use of high reflecting and skid resistant plastic markings e. must be used only high reflecting and skid resistant plastic markings

6.4

Operations

Following are shown the safety treatment under consideration. The safety treatment are divided in two main operation categories, diffused and punctual operations. •

diffused operation are referred to the full extension of the studied section;

•

punctual operation are referred to short sections and specific points inside of the studied section
