Mobility (2000): The Free Traffic Simulator Built on Real Urban-Planning Research
Status unclearYear: 2000 · Developer: Glamus · Publisher: Freeware · Platform: Windows 95/98 · Theme: Business
Most city-building games from this era treat their underlying economic and traffic models as a means to an end: something plausible enough to support the fun, rarely built to withstand real scrutiny. Mobility took the opposite approach. Glamus, the German developer behind it, built the game’s traffic and economic simulation with direct scientific support from Weimar’s Bauhaus University and the traffic research department of DaimlerChrysler, an automaker, not a game studio, lending its actual transport-planning research to a freeware title.
That pedigree shows up directly in how the game plays. Where SimCity abstracts traffic into a simplified overlay and Transport Tycoon focuses narrowly on the logistics of moving goods and passengers, Mobility sits between the two, layering genuine urban-planning and environmental-impact modeling underneath decisions that, in most city-builders, are purely cosmetic. Spatial planning choices ripple through professionally modeled consequences rather than a designer’s best guess at what traffic “should” do. Glamus’s own framing at the time was blunt about the ambition: the underlying technology, they claimed, was new to CD-ROM game production specifically because it let the game depict situations that actually resembled reality rather than a game’s approximation of it.
None of that would matter if the game weren’t also playable, and by most accounts it clears that bar comfortably. SVGA graphics with substantial zoom capability keep the city legible at multiple scales, and the interface, while it takes real adjustment, settles into a manageable learning curve once the connection between your decisions and their downstream traffic effects becomes visible. That delay between cause and visible effect is itself a byproduct of the realism: a genuinely modeled traffic system doesn’t respond instantly the way an arcade simulation would, and patience with that lag is part of what the game asks of its players.
The most striking claim about Mobility isn’t really about the game at all. It’s about what the game was apparently good enough to be used for. The suggestion that its level of modeling made it suitable for actual urban-planning classroom use, more so than SimCity, is a genuinely unusual bar for a free Windows game released by a small developer in 2000 to clear. Whether it was ever formally adopted that way isn’t something that can be confirmed here, but the underlying research partnership behind the claim is real and specific enough to take seriously rather than dismiss as marketing.
How to run it today
Mobility targets Windows 95/98, so a period-accurate virtual machine or compatibility-mode execution on a modern Windows install is the most reliable path to running it today; it isn’t a DOS title, so DOSBox doesn’t apply. Community reports on freeware-preservation sites suggest most core functionality survives compatibility-mode execution, though graphics-driver quirks on very old SVGA code can occasionally require a VM instead.
Compatibility: Windows 95/98 (compatibility mode or VM) · Controls: Mouse-driven, standard city-builder interface · Setup difficulty: Medium
Legal status
Glamus distributed Mobility as freeware through its own official website, but there’s no confirmed evidence that developer or site is still active today, and no official successor or re-release has surfaced. That leaves the game in the common freeware-preservation situation: originally distributed with clear permission to use it for free, but with no currently confirmed maintainer standing behind that original permission today.

Frequently asked questions
How is Mobility different from SimCity or Transport Tycoon?
It sits between the two, combining SimCity's city-building framing with Transport Tycoon's transport focus, but its economic and traffic models are built on actual research rather than simplified game logic, a distinction the developer explicitly built the game around.
What research went into Mobility's traffic models?
Glamus developed the underlying models with scientific support from Weimar's Bauhaus University and the traffic research department of DaimlerChrysler, according to the developer's own description of the project. That's an unusually academic pedigree for a freeware city-builder.
Is Mobility hard to learn?
The interface takes some getting used to, and the connection between a policy decision and its downstream traffic effect isn't always immediately visible. Once that feedback loop clicks, though, the learning curve reportedly flattens out quickly.
Who made Mobility, and is it still free?
Glamus, a German developer, released it as freeware in 2000 through their own official site. Whether that original distribution channel is still active today is a separate and less certain question.
