Abstract [en]

Sustainable transportation is a top priority challenge for many cities and urban regions. To reach that, an attractive public transport plays a key role. In this paper an analysis of how the technology of self-driving vehicles, and in particular shuttles for about 6-20 passengers, can complement and improve attractively in public transport. Self-driving shuttles provide a new component to public transport, as smaller vehicles can operate on a higher frequency to a cost of the same order of magnitude as conventional larger buses. Six types of applications of self-driving shuttles in public transport are identified: Feeder line, Truncation of high capacity line, Cross connections, Center line, On-demand feeder line, and Within-area service (line or on demand). The application types are exemplified by two potential cases in Stockholm, and implementation barriers and strategies are discussed. The classification, together with examples from on-going applications, suggests that SD shuttles can contribute to public transport already without being fully self-driving everywhere.

Abstract [en]

The paper evaluates the impact of real-time crowding information (RTCI) provision based on a pilot study at a Stockholm metro station. During a 6-day test period, RTCI for each car in the next arriving train was provided through a visual display and speakers. The impact is evaluated in three dimensions: (1) passenger attention is analyzed using video analysis; (2) passenger valuation is evaluated with traveler surveys; (3) passenger action is analyzed with in-vehicle passenger load data. It is estimated that around 25% of the passengers noticed, understood and considered the provided information useful for their travel decisions. Further, RTCI had a statistically significant positive impact on the boarding distribution between cars and, as a result, on the downstream in-vehicle crowding in the trains. RTCI reduced the share of passengers boarding the first, most crowded car by 4.3% points for trains that were crowded on arrival, and increased the share of passengers boarding the second, less crowded car by 4.1% points. The findings also suggest that many passengers may value the provided crowding information positively even though it does not change their travel decisions. The results indicate that RTCI may be a useful technology for public transport operators and agencies for increasing the utilization of available train capacity and reducing crowding.

Abstract [en]

In the Green Train research programme, the objective is to develop an attractive trainconcept in the form of a concept proposal based on economic assessments. Green Trainis to be an attractive express train for both business and leisure-time travellers. Highstandards of comfort can be motivated by passengers’ willingness to pay. One fundamentalidea is the wide carbody for services in Scandinavia to achieve lower total costsfor train traffic than a carbody with a normal, quite narrow European continentalprofile. The trains are thereby made shorter and 2 + 3 seating arrangements areoptimised for optimal comfort. Another principle is that the train must be designedto allow punctual station stops, also during periods of peak load. Boarding andalighting must take place within very tight margins, which means that doors, entrancesand luggage racks must be in well-considered locations and correctly dimensioned.

Abstract [sv]

Vilken befolkningstäthet behövs för BRT? En av förutsättningarna för att inrätta kollektivtrafik med god eller någorlunda god ekonomi är att många medborgare har samma resbehov samtidigt. Ett underlag för en BRT linje ligger på minst 5 000 dagliga resor enligt det amerikanska synsättet. I en stad eller stadsregion med en låg andel kollektivtrafik (ca 10 % i Karlstad och 5 % i Värmland) behövs mellan 33 000 till 42 000 boende och arbetsplatser för 10 minuterstrafik och 70 000 för 6 minuterstrafik samordnade i ett stråk.

I genomsnitt gör en person 1 000 enkelresor per år, eller ca 3 resor per dag. Med låg andel kollektivtrafik kommer stora befolkningstäthetskrav. En utmaning är att uppnå 5 000 dagliga resor även med 5 000 boende och arbetsplatser. Det är möjligt om det finns ett urbant nätverk där kollektivtrafiken ligger centralt och attraherar en stor del av resandet i en stadsregion. Ett nätverkstänkande behövs för kollektivtrafikanpassad samhällsplanering och stadsutveckling. Många städer utvecklades inte linjärt och ibland behövs det flera BRT linjer i ett nätverk med viktigaste målpunkter som tunga bytespunkter i täta miljöer med blandade funktioner. Undersökningen i Karlstad har visat att urbana funktioner som handel och institutioner generar nästan dubbel så många dagliga resor per person.

Vi föreslår TOD som en stegvis samhällsplaneringspolicy för anpassning till kollektivtrafiksinfrastruktur. Det handlar om att planera kollektivtrafikens stråk i nätverk med befolkning och verksamheter som trivs vid kollektivtrafik. En postmodern utmaning är att skapa multimodala urbana nätverk i en stadsregion. BRT har egenskaper likt en minitunnelbana och kan möjliggöra detta. BRT är inte målet i sig, men ett verktyg att uppnå ett urbant nätverk. Målet är ju en levande stad där det också är lätt att resa för alla. Det handlar om mjuka och hårda TOD åtgärder på läns och kommunnivå, om stadsförändring och transformering. Ordningen hus, parkering och busshållplats kan ändras. Kollektivtrafiken kan främjas i staden och prioriteras i stadsbebyggelsen.

Abstract [en]

One of the ideas selected for development in the Green Train research and development programme is active secondary suspension. Bombardier Transportation, Sweden, has with support of KTH designed and tested both active lateral suspension (ALS) and active vertical suspension (AVS) that can improve the ride comfort and make higher speeds possible on existing tracks. The two active suspension systems were evaluated with passengers to allow KTH Railway Group to capture their perceived differences in ride comfort.

Our conclusion is that active secondary suspension (ALS/AVS) improves perceived comfort and makes it easier for passengers to move about the train while it is motion while an increase in speed (from category B to category C) has an opposite effect of approximately the same magnitude. This shows that active secondary suspension can contribute to permitting higher speeds on conventional lines with imperfect track geometry.

The higher uncompensated lateral force on bends resulting from higher speeds (category C), however, makes it significantly more difficult to move about the train for travellers with reduced mobility and this needs to be taken into consideration.
