Freight transport has serious environmental impacts on both local and global scales and consumes substantial amounts of energy. Paces committee states freight transport consumes approximately 10 percent of total energy consumption of the Czech Republic with growing trend. This results in EU and national level policies aiming to reduce the impacts. The web-based GIS service Haulier´s Portal enables combining services of multiple hauliers with two aims in mind: support for combined transport and decreasing the share of empty/underutilised freight trips. Two types of transport services are implemented: scheduled connections (e. g. return trip of an empty truck) and transport services with on-demand departure times (e. g. delivery services or more complex transport services). The user can search for optimum connection considering the combination of price, time and energy consumption and book the transport services. The user interface combines web forms and Google Maps map services. The server side is based on Python programming language with CherryPy web server, SQL database and QGIS for shortest path search for individual edges. The connection search is based on modified Dijkstra algorithm based not only on edge cost but also on exact departure and arrival times of scheduled connections and generating edges representing of transport services in each step of computation. The system also implements XML communication protocol for collaboration with third-party software certified by Ministry of Transport. We believe the use of Haulier´s Portal can not only help to reach the aims of reducing environmental impacts and improving energy efficiency of freight transport, but also support smaller hauliers due to increased synergy effects.
