Road transportation impact on Ghana's future energy and environment

Faah, George 24 July 2009 (has links)
This research work explored the environmental and socio-economic benefits derived, if some proportion of daily passenger trips made using private cars in Ghana could be shifted to the use of public transport. The research applied the computer software COPERT III in estimating road transport Greenhouse gas (GHG) emissions and fuel consumption in Ghana for the base year 2005 and forecast years 2010 and 2020. The research reveals that if no major change occur in policies or economic determinants in meeting road transport and energy in Ghana, then the 2005 total emissions value is expected to rise by 36% in 2010 and over double in 2020 i.e. from 4.6 to 6.25 in 2010 and to 9.77 Mt CO2e in 2020. However, if just 10% of daily passenger trips using private cars can be shifted towards the use of public transport, then the end results in reduction in emissions could earn Ghana about $USD 6.6million/year under the Kyoto Protocol CDM initiative. The research also demonstrated that with a further 10% daily passenger trip shift, the outcome could be more promising, increasing to $USD 13million/year.

Shared Autonomous Vehicles Implementation for a Disrupted Public Transport Network

Jaber, Sara, Mahdavi, Hassan, Bhouri, Neila 23 June 2023 (has links)
The paper proposes the management of bus disruption (e.g. fleet failure) and maintain a resilient transportation system through a synergy between shared autonomous vehicles and the existing public transport system based on the organizational structure and demand characteristics. The methodology is applied to the region of Rennes (France) and its surroundings.

Stauidentifikation auf Grundlage der Positionsdaten von ÖV-Fahrzeugen im Mischverkehr

Körner, Matthias 04 April 2017 (has links)
Von Fahrzeugen des Öffentlichen Verkehrs sind deren Positionen bekannt, wenn sie informationstechnisch in ein Betriebsleitsystem eingebunden sind. Über die auf dem Streckenband zwischen Meldepunkten zurückgelegte Wegstecke und die jeweils dafür benötigte Zeit kann auf die mittlere Geschwindigkeit geschlossen werden. Aus dieser wiederum kann eine Verkehrslageaussage abgeleitet werden. In wie weit diese für den Gesamtverkehrsstrom gültig, belastbar und richtlinienkonform ist, welche Randbedingungen für eine Auswertung einzuhalten sind, welche Verfahren sich zur Aufbereitung anbieten und welche Nutzungsszenarien unterstützt werden, wird aufgezeigt.
