| Factor | Impact |
|---|---|
| Time of Day | Peak hours (7–10 AM, 5–8 PM) add 30–60 min; night buses often faster. |
| Day Type | Weekends/holidays = heavier leisure traffic (Lonavala/Khandala hill station rush). |
| Weather | Monsoon (Jun–Sep): fog, rain, landslides possible → delays. Winter fog (Dec–Jan) on ghat section. |
| Bus Type | Volvo/Scania AC (Shivneri, Ashwamedh) faster, fewer stops. Ordinary/Non-AC more stops, slower. |
| Route | Expressway (direct) vs. Old NH48 (via Khopoli, Lonavala — scenic but +30–60 min). |
