The Truck Factor designates the minimal number of developers that have to be hit by a truck (or quit) before a project is incapacitated. It can be seen as a measurement of the concentration of information in individual team members. We calculate the Truck Factor for 133 popular GitHub applications, in six languages. Results show that most systems have a small truck factor (46% have Truck Factor...

OBJECTIVE This study presents data from a large-scale anthropometric study of U.S. truck drivers and the multivariate anthropometric models developed for the design of next-generation truck cabs. BACKGROUND Up-to-date anthropometric information of the U.S. truck driver population is needed for the design of safe and ergonomically efficient truck cabs. METHOD We collected 35 anthropometric d...

To examine the relationship of ramp design to truck accident rates, this paper presents an analysis of truck accidents in Washington State, plus a comparison to limited data from Colorado and California. We group freeway truck accidents by ramp type, accident type, and by four conflict areas of each merge or diverge ramp. We then compare these groups on the basis of truck accidents per location...

With the rapid growth of global container trade volume and trend large-scale ships. The collection distribution port efficiency capacity terminals in various countries are facing huge challenges. Due to randomness most trucks entering port, often face problem traffic congestion caused by centralized arrival load operation yard equipment. Therefore, terminal operators urgently need manage optimi...

For an LTL (Less-than Truckload) carrier, the allocation of doors at a consolidation facility to outbound trailers assigned to various destinations, and to inbound trailers in the continuous stream arriving from various origins, has a significant impact on its operations, and on the nightly man-hours needed for consolidation. In the past literature door allocations to destinations of outbound t...

Motivated by the field sta routing and scheduling problem of an Austrian infrastructure service provider, which involves the planning of subroutes, we study the truck and trailer routing problem (TTRP) [2]. In the TTRP, two types of customers are considered: customers that can be visited by a truck pulling a trailer (denoted as vehicle customers) and customers that can only be visited by a truc...
