Ideal location to commute

So we are a family of 4 all having a need to commute to different places on a daily basis. One to siruseri one to anna nagar one to Perungudi . My mom has an option of choosing work location as either Sholinganallur or egmore which she hasn't done yet. Anna nagar now stands odd one out being the farthest. I'm confused in choosing a area to relocate so that every one has minimal commuting time. Since I'm new to chennai I'm unsure of what area to choose. Kindly suggest me an ideal location
