Important results from the project
Transport industry need to be more effective. The project have investigated vehicle combinations for implementation of BK4 and longer vehicles than 25.25 m in Sweden. Research questions: test, analysis and development of vehicle combinations, type vehicles as base for laws, regulations and standards in Sweden and internationally goals: Energy consumption lowered 7-30% Recommendations for Nordic task group for HCT-regulation 3D simulations of type vehicles Collections of roles that is needed Approval for technical testing: 4
Expected long term effects
Longer and heavier combinations show large potential for increased energy- and transport effectiveness. Vehicle combinations must be handled as one unit. Important requirements are: Start ability Pass ability, stability and drivability Braking performance Development of 3D models and monitoring of fuel consumption has been made. Tests and simulations have shown that lift able axels improve stability at high speed and manoeuvrability at low load. The Nordic rules for HCT should be coordinated in a working group.
Approach and implementation
Designed vehicle combinations and requested permission for test on public roads. Vehicle combinations have been tested in actual transports. Data has been collected through automatic and manual operations. The data are compiled to show the effect of HCT combinations which verifies the increased transport efficiency. Full scale tests has been performed on test tracks to verify simulations. Additional vehicle combinations has been simulated. A mapping of present rules in Nordic countries has been made.
