Traffic　accidents　are　common　in　advanced　warning　areas　of　a　maintenance　work　zone.　One　of　the　reasons　for　the　accident　is　that　the　complex　driving　environment　of　the　warning　area　makes　drivers　need　to　change　lanes　and　speed　frequently.　Another　reason　is　that　driving　distractions　shift　the　driver＇s　mental　workload　and　make　the　drivers　unable　to　complete　the　driving　task　well.　The　paper　aimed　to　examine　the　impact　of　visual　and　cognitive　distractions　on　the　driver＇s　mental　workload,　eye　movements,　and　driving　behaviour　when　driving　in　advanced　warning　areas　of　the　maintenance　work　zones.　Thirty-two　participants　(mean　age　=　23.97　years)　participated　in　the　experiment　and　completed　3　advanced　warning　area　simulation　scenes.　The　road　initial　speed　limit　of　simulation　scenes　was　different:　60　km/h,　80　km/h　and　100　km/h.　The　drivers　needed　to　pass　three　scenes　under　three　types　of　distraction　tasks　(no　task,　visual　task　and　cognitive　task).　Six　indices　were　used　to　evaluate　the　effect　of　the　advanced　warning　area　and　the　distracting　secondary　tasks　on　the　driver＇s　mental　workload:　two　related　to　eye　movements,　two　related　to　driver　behavior,　and　two　related　to　the　electroencephalogram.　The　TOPSIS　analysis　was　used　to　solve　the　problem　of　multi-evaluation　indices　comparison,　sorting　and　selection.　The　results　show　that　the　driver　has　higher　vehicle　control　ability　under　the　distraction-free　task　condition　than　in　other　scenes.　Furthermore,　the　impact　of　visual　distraction　on　drivers　is　more　significant　than　that　of　cognitive　distraction,　suggesting　more　visual　attention　is　required　for　drivers　when　passing　the　complex　working　zone.　©　2023
