evaluate the other vehicles positions and minimize travel times and wait times. The device would work autonomously within existing roading systems so as not to consume additional energy in the construction of new rail or roading infrastructure.

Power storage and distribution is not the design focus of the device. The fuel cell option was chosen to minimise development timeframes but the modular construction would allow for super capacitors and other new generation storage components to be inserted within the device at a later date, superceding the outdated component.

The continuous flow of these vehicles is where the system performs. Unlike human controlled vehicles these devices have regular gaps between them to allow a constant flow of vehicles to move across the path. This constant speed and regular distribution is where the energy efficiency is maximised with the pick up and drop off being the only times the vehicles stop. The ownership of the vehicles resides with communities. Private vehicles would be removed from cities entirely, transfering the embodied materials from private cars into the new devices. Distribution firms and delivery services alike would have the ability to “lease vehicles” and brand them but the physical layout would match the standard platform so as not to disrupt traffic in any way. It is also anticipated the integrated private freight and personal transit could co-exist within these vehicles.

The proposed year of installation is projected for 2020. This coincides with the current estimation of the peak production of fossil fuels. The aim of the Salvais is to eliminate the congestion problems currently faced within first-world cities that already have the infrastructure for cars in place. The team identified developing cities that may be able to build around LRT and MRT systems with fewer impacts to the environment.

The Salvais will cater for up to 16 passengers at once when standing in commuter mode, and through minor configuration changes to the seating is able to accommodate multiple user modes. The focus of the device was to allow the larger community access to a vehicle that would cater for special needs, events, freight and storage for city trips and interaction.

The different modes of use allow every device to become an emergency device. The dual wheel configuration allows for independent control over obstacles and the interior cabin with its unobstructed seating configuration allows for lying passengers to rest safely while on route to medical centers.

As sited by Midgley,1994 ; some developing cities have current inner city speeds of 8-10kph. With the potential growth of HPV’s (Human Power Vehicles) able to deliver speeds of 300% on this value, it is critical that new transport solutions work with HPV and improve the safety of the HPV rider, while providing a service for less able, aged, weather or load determinate travel requirements.

On considering relevance to a design solution it is critical to assess how the change of one system can benefit another. The Salvais in itself may not yield sustainable transportation but may lead to opportunities in other HPV’s that can.
