Körspår för lastbil - Tidsstudie och utrymmeskontroll i Auto Turn
(2014)Programmes in Helesingborg
- Abstract
- Traffic engineers around the country often use pre-programmed path plans. However, there is often an uncertainty in how much margin there is in the path plan and if they are trustworthy. The goal of this report is to determine the margin in pre-programmed path plans, using the program AutoTurn, for trucks with a length of 10 meters. This report discusses drive and rest times how both the drive and rest times depend on the drive time of different paths to reverse in to goods receptions. A time study has been performed and a path plan study as well as interviews to obtain a sufficient amount of data. The time study was conducted at two supermarkets in Sweden during February 2014.

- Traffic engineers around the country often use pre-programmed path plans. However, there is often an uncertainty in how much margin there is in the path plan and if they are trustworthy. The goal of this report is to determine the margin in pre-programmed path plans, using the program AutoTurn, for trucks with a length of 10 meters. This report discusses drive and rest times how both the drive and rest times depend on the drive time of different paths to reverse in to goods receptions. A time study has been performed and a path plan study as well as interviews to obtain a sufficient amount of data. The time study was conducted at two supermarkets in Sweden during February 2014. These supermarkets were chosen after inventorying industry plots, bigger and smaller stores, supermarkets and malls with a goods reception. One criterion was that the goods reception had to be enclosed by a fence and there should also be many deliveries every day to get a sufficient amount of data. 80 trucks where studied, and the time it took to reverse and the time the trucks spent on the area were recorded. The results of the time study were used to choose the three paths to include in the path study. The three path plans were tested in AutoTurn and were measured. Then a field study was conducted for two days in the beginning of March 2014, and three path plans were tested with a truck of the type Scania Highline and with a length of 10 meters. The results from the time study show that the majority of the trucks reverse to the goods reception in 30-39 seconds. The time of reversing varies between 20 to over 60 seconds. At the two different goods receptions, the time the trucks spent in the area varies between four minutes and up to 60 minutes. The results from the path study show that the path plans are not the same in reality as in the program. The path plans in AutoTurn is more generous with margins and takes more space than a 10 meter truck does in reality. The conclusion is that trucks with a length of 8-12 meters with unloading that contains unboxing inside the markets drive and rest times are not affected by the time of reversing can be made from the interviews and the survey. As only two goods receptions and 80 trucks were studied, it is not possible to make any general conclusion of how the reversing time affects the drivers’ drive and rest times. There are margins in AutoTurn when a truck drives forward to the right with full steering angel. The margins are between 0,73 m to 3,90 m.
