1. 1. Tankemotståndet mot sociala skillnader som transportplaneringsfråga : En analys av planeringstänkande på Trafikverket

   Författare :Karin Winter; Jonathan Metzger; Dalia Mukhtar-Landgren; KTH; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; transportplanering; Trafikverket; diskursanalys; diskursteori; sociala skillnader; Urbana och regionala studier; Urban and Regional Studies;

   Sammanfattning : I transportplaneringssammanhang står sällan sociala skillnader i centrum för vad som diskuteras och analyseras. Förvisso har social hållbarhet under de senaste åren blivit ett viktigare svenskt planeringsbegrepp men i transportplaneringskretsar uppfattas det ofta som något nytt och främmande. LÄS MER

3. 2. Development of critical enablers for Unmanned Traffic Management

   Författare :Leonid Sedov; Valentin Polishchuk; Tobias Andersson Granberg; Yan Xu; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : As the interest in drones continues to grow in both commercial and leisure markets, governments around the world are preparing to face the new challenges arising from unmanned operations. Safe and efficient handling of this novel drone traffic warrants an Unmanned Traf-fic Management (UTM) system capable of dealing with the envisioned high traffic densities. LÄS MER

4. 3. Towards microscopic models for bicycle traffic simulation

   Författare :Guillermo Pérez Castro; Johan Olstam; Fredrik Johansson; Heather Kaths; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : As bicycling becomes an integral part of sustainable mobility, it becomes essential to enhance planning strategies that ensure bicycling as an efficient mode of transport. While traffic simulation has been extensively utilized for traffic planning of various modes of transport, this type of modeling support is largely lacking in the planning of bicycle traffic.

5. 4. Optimization of Aircraft Arrival Operations for Improved Environmental Efficiency

   Författare :Henrik Hardell; Tatiana Polishchuk; Valentin Polishchuk; Ramon Dalmau-Codina; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : The transportation sector, accounting for about one fifth of all greenhouse gas emissions, is facing a significant transformation in order to become more climate-friendly. In terms of air transportation, there are several important steps on the way to making flying sustainable both for the planet itself and for people directly or indirectly being exposed to its effects.

7. 5. Improving the Efficiency of Public Procurement : Empirical evidence using micro-level contract data

   Författare :Ivan Ridderstedt; Hans Lööf; Jan-Eric Nilsson; Kristofer Odolinski; Sofia Lundberg; KTH; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Public procurement; public sector efficiency; auction design; award mechanisms; bundling; transport infrastructure; public transport; Nationalekonomi; Economics;

   Sammanfattning : Among OECD countries, close to one-third of government expenditure is allocated using public procurement. This implies that the skill of public authorities in handling the procurement format has a significant impact on how much the public sector accomplish in relation to their goals and responsibilities.
