Optional features could include sensors to keep it from colliding with a person or object (such as an overheight vehicle in front), warning lights and safety curtains at the rear to keep drivers of overheight vehicles from going underneath, repeater traffic signals underneath to relay the indications of traffic signals up ahead, and animated light displays to simulate stationary objects to prevent disorientation of drivers underneath.

After the fire, a militia rescue organization, the Wiener Freiwillige Rettungsgesellschaft, was founded. It lasted until 1938 and its duties were taken over by the Viennese city council after the war. Then, fire prevention measures were enacted. Safety curtains became mandatory in order to contain stage fires and theatre props had to be impregnated to make them fire- resistant.

51 The heavy, flame-retardant house tabs can provide some degree of fire separation. In the UK, it is a requirement that a safety curtain must be fully down within the proscenium opening within 30 seconds of being released. In 1794 the Theatre Royal, Drury Lane became the first theatre to feature an iron safety curtain. Several other serious fires, notably that at the Theatre Royal, Exeter in 1887, led to the introduction of safety curtains on a wider scale.

The ruins of the fire at the Ringtheater, 8 December 1881 Given that the footprint of the theatre was small—and the theatre was intended to hold an audience of 1700—the architect was forced to build high, but with disastrous consequences. On December 8, 1881, a fire broke out shortly before a performance of Les contes d'Hoffmann,Zeitzeichen auf WDR 5 am 8. Dezember 2006 and 449 people were killed. The following year, a new law was passed, regarding the outfitting and safety provisions, including safety curtains, outwards-opening doors and fireproofing of the set.

It would have inflatable evacuation slides similar to those of an aircraft. Optional features could include sensors to keep it from colliding with a person or object (such as an overheight vehicle in front), warning lights and safety curtains at the rear to keep drivers of overheight vehicles from going underneath, repeater traffic signals underneath to relay the indications of traffic signals up ahead, and animated light displays to simulate stationary objects to prevent disorientation of drivers underneath. According to the 2010 proposal, it would cost about 500 million yuan (~ million) to build the bus with a guideway. This is claimed to be at 10% of the cost of building an equivalent subway, and is estimated to reduce traffic congestion by 20–30%.

The company was set up by an Act of Parliament (the London Hydraulic Power Company Act 1884), sponsored by railway engineer Sir James Allport, to install a network of high-pressure cast iron water mains under London. It merged the Wharves and Warehouses Steam Power and Hydraulic Pressure Company, founded in 1871 by Edward B. Ellington, and the General Hydraulic Power Company, founded in 1882. The network gradually expanded to cover an area mostly north of the Thames from Hyde Park in the west to Docklands in the east. The system was used as a cleaner and more compact alternative to steam engines, to power workshop machinery, lifts, cranes, theatre machinery (including revolving stages at the London Palladium and the London Coliseum, safety curtains at the Theatre Royal, Drury Lane, the lifting mechanism for the cinema organ at the Leicester Square theatre and the complete Palm Court orchestra platform), and the backup mechanism of Tower Bridge.
