Abstract [en]

The purpose was to study the effect of vehicle length on meeting margins during overtaking maneuvers. A field study video-recorded overtaking maneuvers of a 30 m and a 24 m truck on a two-lane road. The difference in average meeting margins between the trucks was not statistically significant. An ocular assessment of the video material revealed a few critical situations during the overtaking maneuvers of the 30 m truck; all with meeting margins less than 3 s. Although these results should be interpreted with great caution as the number of analyzed overtaking maneuvers was limited, two previous studies describe similar findings. The conflict technique is discussed as a tool in the assessment of critical meeting margins. It is concluded that more field studies and data are needed to estimate the risks when overtaking Longer Combination Vehicles.

Abstract [en]

The purpose of this paper is to investigate if the introduction of extra-long and heavy trucks has an effect on traffic safety on Swedish roads, especially in relation to overtaking maneuvers. Traffic safety effects will be measured in terms of road user behavior concerning accelerations and time slots. First, focus group interviews with heavy truck drivers. Truck drivers that do not drive extra-long trucks believe that the introduction of extra-long trucks will create a number of traffic safety problems especially in terms of conflicts with ordinary road users. The drivers of extra-long trucks do not experience the problems that ordinary truck drivers predict. The problems they experience can be taken care of with more planning (thinking ahead). They also believe that the traffic sign on the back of the extra-long vehicle has a positive effect. The truck company, working environment and truck equipment are other important aspects mentioned by the drivers of the extra-long vehicles.

The simulator study investigates overtaking situations on a 2+1-lane highway, with extra-long trucks (30.4 m) and ordinary trucks (18.75 m). The results reveal that the distance from the rear/front of the truck to the point where only one lane exists affects car drivers’ decision to overtake, independently of truck length. If the truck is in the relatively same position, the timeslot for a safe overtaking maneuver before next one-lane section was reduced significantly for extra-long trucks compared to ordinary trucks. The conclusion is that there exist small tendencies which point in the direction of enhanced traffic safety problems with the introduction of extra-long trucks. The results should, however, be interpreted with caution as the number of data points was few and collected in specific situations and in specific conditions. It was neither considered how the introduction of longer and heavier trucks, given a constant amount of goods, reduces the number of heavy trucks on the road network.

Traffic safety effects when overtaking 30 metre trucks
Abstract [sv]

Trafikverket överväger att tillåta längre och tyngre fordon på vägarna förutsatt att de inte påverkar trafiksäkerheten negativt. Syftet med studien var att undersöka säkerhetseffekten av fordonslängd, speciellt med avseende på olycksrisken vid omkörningar. Intervjuade förare av en 30-meters timmerbil hade inte upplevt de farhågor som förare av normallånga lastbilar uttryckt i samband med trånga rondeller och korsningar, men de nämner betydelsen av stödjande åkeri, arbetsmiljö och fordonsutrustning. En simulatorstudie studerade bilförares omkörningar av ett 30- och ett 18,75-metersfordon på en 2+1-väg i situationen då två körfält går ihop till ett. Tidluckan till ett återstående körfält var i genomsnitt 0,2 s (sign.) kortare efter omkörningar av 30-metersfordonet i situationer då bakänden var i samma relativa position som för 18,75-metersfordonet vid början av omkörningen. En fältstudie analyserade videoinspelade omkörningar av en 30- och en 24-meters timmerbil på en 2+1-väg och en tvåfältig väg. Ingen signifikant skillnad i tidluckor kunde påvisas mellan omkörningar av de två fordonen för någon av vägtyperna. Det senare resultatet ska dock tolkas med försiktighet på grund av ojämnt distribuerad data som insamlats under specifika förhållanden. Slutsatserna är att det finns en liten tendens till negativ säkerhetseffekt vid omkörningar av längre fordon, och att fler fältstudier är nödvändiga.

Abstract [en]

The Swedish Road Administration considers permitting longer and heavier trucks on Swedish roads, provided that they do not affect traffic safety. The purpose of the study was to investigate the effect of truck length, particularly accident risk associated with overtaking. Interviewed drivers of 30 meter trucks had not experienced the problems predicted by drivers of ordinary trucks concerning narrow roundabouts and intersections, but mentioned the importance of a supportive truck company, working environment and truck equipment. A simulator study investigated car drivers overtaking trucks 30 m and 18.75 m long on a 2+1 road where two lanes merges to one. The headway time gap was 0.2 sec. (sign.) shorter after overtaking the 30 meter truck in situations where the back was in the same relative position as of the 18.75 meter truck. A field study analysed video-recorded overtakings of a 30 meter and a 24 meter timber truck on a 2+1 road and a two-lane road. No significant differences were found between headway time gaps when overtaking the two trucks, regardless of road type. The latter result should be interpreted with great caution because of unevenly distributed data collected during specific conditions. The conclusions are that longer trucks may have a small negative effect on overtaking situations, and that further field studies are required.

Abstract [en]

Purpose: Most school bus related injury events in Sweden take place when the child is outside the bus. In order to enhance their safety, the societal costs of four different measures applied on “bus stops” on high speed roads were investigated.

Methods: From a door-to-door perspective, a measure hierarchy, comprising the four existing measures, viz.: Rerouting using the current operating vehicle, New construction, Rerouting using a different operating vehicle, Speed reduction in the vicinity of the “bus stop” was applied.

Results: By allocating 7.7 € per child per school day, almost nine out of ten children’s transportation safety may substantially be enhanced, simply by rerouting the current operating vehicle or using alternative operating vehicles.

Conclusions: In the investigated municipality it was feasible to enhance school transportation safety for children by implementing cheap and alternative measures.

Abstract [en]

The evaluation of active safety functions like Electronic Stability Control (ESC) is of increasing importance, driven by legislation, to commercial heavy vehicle producers and to society as a whole to predict the potential benefits of the systems. Direct testing in real traffic with normal drivers of those functions are most often infeasible due to cost, repeatability and safety. This paper presents an attempt to explore the possibility of using large scale moving based driving simulators to evaluate functions like ESC. This is conducted through a simulator experiment where the subject drivers have been provoked in driving scenarios to ESC interventions. The experiment indicates the possibility of using driving simulators for evaluation purposes. This implies that studies of the benefits can be performed with higher accuracy regarding repeatability and evaluation testing of active safety functions can be made more cost efficient and without jeopardizing safety of involved driver and other road-users.

Smart Safe School Bus : a pilot study in Kristianstad
Abstract [en]

Some 400,000 children go to school by school bus in Sweden every day. The most risky situation is when the child is outside the bus entering or exiting, lack of routines being the major cause. The present study utilised off-the-shelf technology, in order to create a driver support system that raises the level of routines in school transportation and facilitates communication between the drivers and the children. Two buses, driven by seven drivers were equipped with the system during 2008, comprising data for 130 children. Moreover, two bus stops were equipped with flashing lights, triggered by radio transmitters that the children wore. The evaluations of the system showed that it does raise the level of routines and allows the drivers to survey the children in order to take action in case of an emergency. The system has frequently been used in all its parts and been considered useful. Children reported feeling more secure with the system and experienced less stress as a benefit of it. The average speed of cars has significantly been reduced by the flashing bus stops. For the cost of 0.5-2 SEK per school day and child, the system could prevent fatal injuries in school transportation, generating monetary benefits on a societal level.
