Abstract: Nowadays, the development of ICT has had a positive impact in the management of transportation system since they can provide useful information for citizens and local administration in real time. On the other hand, family habits related to children’s displacements to school have changed, increasing motorized displacements against active modes. In order to reverse this situation, Walk to School programs are being developed by local administrations. One of the possible actions in these programs is the walking school bus. This article presents a study about the feasibility of a technological tool for the management and coordination of walking school buses: Trazeo. It has been checked that this tool increases the parental confidence on walking routes to school promoting safe, healthy and sustainable habits among children.

Abstract: Design-Build(D&B) contracts, compared with traditional Design-Bid-Build(D-B-B) contracts, are regarded as a total accountability style of contracting, with everybody on the same team. For public projects, D&B is a kind of relatively low risk procurement option for the employer, in terms of cost and time. As the stages of design and build can be carried out in parallel by the same party, the liability of design errors has been casted on the contractor. Therefore it is found the entitlements of variations in D&B projects are less than D-B-B projects. In this paper, the D&B projects completed between January 2010 and March 2015 were explored. There were 402 D&B projects among 7,082 civil engineering contracts in this period of time. It revealed that the main factors of variations of D&B projects in the past 5 years in Taiwan may be grouped as the changes of the employers’ requirements in design phase and the change orders in construction phases. The analysis of the factors of variation in
