2. 1. Advancing Traffic Safety : An evaluation of speed limits, vehicle-bicycle interactions, and I2V systems

   Author : Ary Pezo Silvano; Haris Koutsopoulos; Haneen Farah; Karl-Lennart Bång; Alfonso Montella; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Traffic safety; urban roads; posted speed limits; road characteristics; free-flow speed; time headway; vehicle-bicycle interactions; logit model; yielding probability; cooperative systems and warning messages.; Transportvetenskap; Transport Science;

   Abstract : Since the introduction of motor vehicles, the number of fatalities and accidents has been a concern for society.The number of fatalities on roads is amongst the most common causes of mortality worldwide (WHO, 2015).Even in industrialized countries the number of fatalities remains unacceptable.

4. 2. Satisfaction with Public Transport Trips

   Author : Roberto Fernandez Abenoza; Yusak Octavius Susilo; Oded Cats; Sigal Kaplan; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; customer satisfaction; public transport; three-factor theory; accessibility; built-environment; weather; door-to-door trips; firs and last-mile; market segmentation; geographical variations; service quality; safety perceptions; temporal variations; Transportvetenskap; Transport Science;

   Abstract : Continuous urban growth, environmental issues, competition for limited space, longer commuting distances as well as the need to promote equity and equality in society are the primary reasons that make the improvement of public transport (PT) services a key policy area in many countries across the globe. Travel satisfaction measures the perceived quality of the PT service and it is an important aspect that operators and PT authorities need to consider when improving the service offered. READ MORE

5. 3. A method for analysing the traffic process in a safety perspective

   Author : Åse Svensson; Trafik och väg; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; intermediate method; Accidents; pedestrian safety; safety hierarchy; severity; traffic conflicts; interaction; road user behaviour; traffic safety; traffic process; time to accidents; safety indicators; surrogate measures;

   Abstract : The aim of this study is to extend the traffic safety assessment concept to also include normal road user behaviour, thus not only exceptional behaviours such as accidents and serious conflicts. The goal is to provide a framework for a more thorough description and analysis of safety related road user behaviour in order to better understand the traffic safety processes. READ MORE

6. 4. Clusters of urban crime and safety in transport nodes

   Author : Adriaan Cornelis Uittenbogaard; Vania Ceccato; Mats Wilhelmsson; Alex Hirschfield; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; safety; urban crime; space-time clusters; crime concentrations; GIS; environmental attributes; public transport; underground stations; transport nodes; crime prevention;

   Abstract : The objective of the thesis is to provide a better understanding of the safety conditions inurban environments, particularly related to those found in transport nodes, in this case,underground stations, and surrounding areas1. First, the study starts with an analysis of theoverall city, identifying concentrations of crime in the urban fabric and then focusing on thecriminogenic conditions at and around underground stations.

7. 5. Exploring societal impacts of self-driving public transport using four-step transport models

   Author : Erik Almlöf; Mikael Nybacka; Erik Jenelius; Mia Hesselgren; Clas Rydergren; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Self-driving vehicles; Public transport; Four-step transport model; Societal impacts; Sampers; Machine Design; Maskinkonstruktion;

   Abstract : During the last decade, self-driving technology has become increasingly visible in the news, with the vision that people would enter vehicles that drive themselves, and that people could instead rest, read the newspaper, or have a meeting. However, these visions have mainly focused on the potential for car usage, even though public transport could benefit greatly from self-driving technology. READ MORE
