Questão jurídica principal
Whether the appeal against the roadworks-related traffic measures was admissible and within the department's competence.
Decisão extraída
The appeal was admissible; the department was competent to order and coordinate the traffic signage measures.
Fundamentação extraída
Under the traffic ordinance, the department is responsible for signaling construction sites, and an appeal to the Administrative Court is available. For affected municipal roads, the department may also coordinate necessary measures by analogy to the rule on mixed cantonal and municipal roads.
