2getthere’s Group Rapid Transit vehicle passes desert climate test

2getthere’s Group Rapid Tansit (GRT) autonomous vehicle has proven in a simulated desert climate that it can maintain an indoor temperature of 23˚C even in the worst scenario (52˚C outside temperature and 3% humidity). The climate test took place in the Utrecht province and is one of many tests regarding the mega-order received from United Arab Emirates earlier this year. From 2020, five vehicles will perform fully autonomous shuttle services to and from Bluewater Island in Dubai.

8172 2getthere’s Group Rapid Tansit (GRT) autonomous vehicle has proven in a simulated desert climate that it can maintain an indoor temperature of 23˚C even in the worst scenario (52˚C outside temperature and 3% humidity). The climate test took place in the Utrecht province and is one of many tests regarding the mega-order received from United Arab Emirates earlier this year. From 2020, five vehicles will perform fully autonomous shuttle services to and from Bluewater Island in Dubai.

GRT was subject to three tests in weather conditions such as ‘hot dry’ and ‘hot humid’ with a focus on the performance of the air conditioning system (ACS) at the vehicles maximum capacity of 24 passengers.

13 ACS has been developed in collaboration with suppliers DC Airco and Netherlands Aerospace Centre (NLR) who used the simulation of heat management in relation to airflow within the vehicle in its design of the air conditioning. Its development has been partly financed through a 2024 Massachusetts Institute of Technology research grant in which DC Airco and 2getthere have both participated.

The simulated weather conditions included extremely high temperatures and sun radiation with average peaks in the sun radiation of 1,040 Watts per square metre and peaks in temperature of 52˚C around 3.30pm. In the climatic chamber, both peaks were simulated at the same time.

The GRT’s 16 standing passengers represented 120 Watts each and eight seated passengers each represented 100 Watts were simulated by placing a 3000-Watt heat source inside the vehicle. Part of the test focused on performance during transition: the speed at which indoor conditions are brought back to the most comfortable level for passengers after the doors close and the vehicle starts its journey. The most extreme test was based on the vehicle standing still with the doors open for six minutes, but in actual circumstances much shorter stops will be sufficient to allow 24 passengers to enter the vehicle and find their seats.

According to 2getthere the test marks another step towards the operational deployment of the system, scheduled for 2019/2020.

    'Keep it simple, stupid' is an oft-forgotten axiom but in terms of road user charging it is entirely appropriate. So says the ANWB's Ferry Smith. A couple of decades ago, it might have been largely true that the technology aspects of advanced road infrastructure were the main obstacles to deployment. However, 20 years or more of development have led to a situation where such 'obstacles' are often no more than a political fig-leaf. Area-wide Road User Charging (RUC) is a case in point; speak candidly to syst

In August, Andrew Cuomo, governor of New York State, described congestion charging for the city as “an idea whose time had come,” according to the Bloomberg wire service. In October, he announced a ‘Fix NYC’ advisory panel to study methods of easing congestion on the city’s streets. Although Cuomo did not specifically mention congestion charging when setting up the panel, he said it would study

This year there is speculation that the work by Siemens of Germany on long distance pure electric trucks being charged by short lengths of overhead catenary could also apply to buses. That should involve much lower cost than the other zero pollution option the fuel cell bus. Now Switzerland has joined other places around the world newly exploring t
